Vastroodes and Vaizards

[uw10isplaya]

Okay, Hitsuyaga says that a vastrode is stronger than any captain/if there are 10+ everyone's screwed, and that they look like humans. All the arrankarus that chill with Aizen have a human arrancar form, so does that mean there are 20+ vastrodes? And if that's so, how come they get defeated so easily in 203? And, how does a strong vizar compare to a strong arrancar i wonder? Hitsuyaga also says that an arrancar should become stronger than any menos, yet says that a menos vastrode is stronger than any captain, so what would that make the vastrode once the hollow mask is taken off? Also, wtf happened to that huge hollow that loomed over the first part of the series. Any speculations or cold hard answers are greatly appreciated.

[jonat3]

I believe the text implied that arrancars and menos are different species. Arrancars are just normal hollows turned into hybrids, while we haven't heard the class name for hybrid menos yet.

A hybrid vastoorode is theoretically more powerful than Yamamoto. If any of the arrancars were vastoorodes originally, only Urquiorra and perhaps Grimmjow have enough power to be one.

[Sandal Hat]

Hmm, since all the arrancars are small as humans then they could be vastrodes that took there mask off and the big ones(like yami, who was weaker) are the ajukas turned into hybrids. Also, everyone knows that d-roy was a failure so that is the reason he was defeated so easily.

[_Ink]

that huge hollow mentioned appears to be the hollow boss...doesn;t it?
my memory is blurred, but i also think there is a possibility it was a powerful menos and the one that is called a vastoorode which apparently these capts already know about

Yeah, but the translation said he was relying on Aizen's gifts, swhich suggests he was already weak to begin with. Even a failed hybrid vastoorode can never be as weak as D-Roy.

[Sandal Hat]

Hitsugaya said that Vastoorodes are the size of humans and there is even a little small picture that helps you out.

Edit: I was replying to devildude

If what you're saying is true, than there would be arrancar, then a hybrid weak menos, then a hybrid med. menos, then a hybrid menos vastrode. If the current arrancar are this strong, there's no way there can be that many levels above them.

According to Hitsugaya, there have existed hollows in the past that matched the menos. If Aizen found these hollows and hybridized them, they might well be equal or even more powerful than a vastoorodes. So a vastoorodes is stronger than the majority of normal arrancars, but there may be a few normal arrancars that can match one. Perhaps there's one that can even match a hybrid vastoorode.

[Polygon]

Can some Tell me the chapter where they talk about the giant hollow. I have a theory but I need that chapter and I can't find it.

[InsaneShiyn]

Sorry, I meant to type"8" not "*"
Are those the Aranchars in the beginning of the Episode?

[Shinji]

Do you mean in the Intro song? Or do you mean a specific episode?

[Zanga]

He means the beggining of the episode. They look like the arrancar, yet Aizen doesn't have the Hougyoku yet...On looks like Ulquorria(sp?) and one looks like the guy who ripped grandfisher's mask off in the manga...

[Caesar]

hmm i thought GF did it by himself!!
back to topic: who knows maybe they were and we couldnt tel at that time.

[Hollow_Man_ct]

also, arrancar don't need the Hougyoku to become ones, they can also use forbidden arts, and btw, didn't Hitsugaya say that gillians are arrancar which the Shinigami text books call "Menos Grande"? that means That Ichigo HAD fought an arrancar before ( without even shikai and he made it return to where it came from, wonder what he can do now?? ).

[Shinji]

But that was a very weak Arrancar. You can't even compare him to the Espada.

Yes, they look like the Arrancars.

[Zanga]

True, but he also beat it cause his spirit power went wacko and crazy. Otherwise X_x

[Hollow_Man_ct]

But that was a very weak Arrancar. You can't even compare him to the Espada.

yeah, I know but still, fighting an Arrancar without even shikai, that's most incredible, then fighting the Espada ( which is a level above Gillians ) Grimmjow WITH bankai and he got pwned, shows how HUGE the difference is between Gillian and Espada, so I agree with you on that last point.

btw, what would have happened if Ishida hadn't shot his arrows carrying Ichigo's reiatsu away? would he have obtained Shikai? ( Judging from the immense Reiatsu emmiting out of the sword )

[MVIK]

didnt Ishida did that so that Ichigo would not like kill himself n the rest because Ichigo cant control his reiatsu at that time n his reiatsu is flowing out non-stop like a water tap that isnt being turn off

[Hollow_Man_ct]

didnt Ishida did that so that Ichigo would not like kill himself n the rest because Ichigo cant control his reiatsu at that time n his reiatsu is flowing out non-stop like a water tap that isnt being turn off

so? what is the mistake in letting your Reiatsu flow? it would make you ( and nearby Quicnies stronger, since they get their power from the SURROUNDING reiatsu, not from their soul ) stronger.

[MVIK]

Rukia stated that because Ichigo suddenly release so much reiatsu to defeat that gilian and he cant control it from flowing out anymore, he would melt himself. Ishida even hurt himself when he was shooting arrows wit Ichigo's reiatsu. So this means that it would kill anyone that is expose to that reiatsu

[Hollow_Man_ct]

oh, thanks for making that clear.

[MVIK]

no problem.... glad i could help

[Undying]

'scuse me, a Gillian (A.K.A Menos Grande) is NOT an Arrancar. This is a type of MENOS, which are normal, NOT hybridized Hollow. Ichigo fought a low class MENOS, which is so far lower than an Espada that it's like putting Hanatarou against Yama-ji.

[Wabisuke]

vastrode are menos that resemble humans, right?

the most powerful arrancar were probably made from vastrode, which explains their appearance even before the hougokyu

[Undying]

No, they are apparently Adjucha, since Aizen says that he is yet to have found all the Vastorode (which are indeed the Menos that are most like human in appearance).

Also, the appearance for most Arrancar is human in nature, rememebr D-Roy? He looked exactly like a human, but was he even a Menos? NO!

[Wabisuke]

hmm yeah i guess just based off of their strength i should have known they weren't vastrode

but does this mean that aizen has developed a method for non menos to tear through dimensions? (i think it was ishida that said something about only menos being able to do that)

*edit* well, scratch that last bit anyway, if grimmjaw is an adjuca.. i guess that explains that

[Zanga]

The espada are the cloest thing Aizen's got to a vastroode so far.

[Wabisuke]

espada was just a word aizen made up to refer to his elite arrancar though, isn't it?

[Byakuya7]

yes Espada refers to Aizens elite arrancar. There are 3 types of hollows which include gilian, adjucas, and vastoorode. The Espada is just the classification of his greatest hybrids.

[Yago]

you were impressed by Ichigo scratching the Menos Grande without shikai? then what about his father tearing up GF...

[Zanga]

Issin pwned GF wasn't really outstanding seeing how he is captain level and all. I was hoping Ichigo would kill him but eh...

[Darkness_becomes (me)]

I'm kind of glad that Isshin got to take him down. GF DID kill his wife, after all.

[Hollow_Man_ct]

Undying, Aren't the menos grande the least form of Gillians as Hitsugaya said? I remember him saying that The arrancar were divided into : Gillian, Adjucha and Vastroode. Also, he said that Gillians are known in Shinigami text books as Menos Grande. And another thing, where does the Espada fit in the Classification of Gillian, Adjucha and Vastroode?

[Zanga]

It's probably a name Aizen gave them signifying that they were his strongestt...so far...

[Undying]

Ah.... you apparently misunderstood. You see, Gillian are the lowest class of Menos. But Menos and Arrancar aren't the same. However, the current Arrancars are, apparently, all Gillians (Menos Grande) hyberdized, with the exception of the Espada, who are either Vastorode/Adjucha hyberdized.

Menos Grande is indeed the term used to describe the Gillians, because all Gillians look the same and are all on the same level of power (which I do not think applies to teh Adjucha and Vastorodes, I think those vary).

And just to avoid further confusion...
Menos types:
1. Gillian - the most common type of Menos Hollows, and are also the weakest Menos. Refered to as "Menos Grande" in the Soul-Society text books beacuse they are all the same - theire appearance and power are all on the same level, without variation. They are dumb. They look like that oversized long-nosed-witch-thingy.

2. Adjucha - the second class of the Menos Hollows, they are by far less common, and are by far smaller than the Gillian and are far more humanoid. It is my personal opinion that they very both in strength and appearance. They look like humans but are far larger - reaching something like 10-15 feet (if we go by Yami who was 2 as tall as Ichigo), and are all smart (at least in comparison to the Gillians, who canno even speak).

3. Vastoode (Vast-Lord?) - the strongest type of the Menos Hollows. They are all humanoid in stature, are all intelligent, and are by far the fewest of the Menos. Capable of overpowering Captains, they are supposedly deep within Hueco Mundo.

Ok, a note: ALL Menos are normal Hollow, their masks are still intact, they haven't ripped it apart.

Arrancars:
The Arrancar split into two categories: Espada and non-Espada.
Non-Espada:
Numbered 11 and below (I mean 11, 12, 13, 14... etc.), they are all, as far as we saw, hyberdized Gillians (i.e. Menos Grande who ripped off their masks), they are somewhere near Captain level (a huge increase of power, a normal Gillian cannot beat a Captain, and the Captain won't even break a sweat beating it), and in intelligence (as we saw all the Arrancars wo came with Grimmjaw to earth were capable of speech and seemed to know how to think, something normal Gillians are yet to master ;)).

Espada:
These are numbered 10 nd above (10, 9, 8, 7... etc.) and are all, supposedly, above Captain level. They seem to be like Vastorodes in terms of power, so they are refered to as "Vastorode Arrancar", when we are cllassifying them by power).

I hope that helped.

[Hollow_Man_ct]

very nice, thanks for clearing that for me. ( I'm being such a pain! )

[Sandal Hat]

The initial point of this thread has been fulfilled, I will change the title to something that fits

[Undying]

very nice, thanks for clearing that for me. ( I'm being such a pain! )
You're welcome and no you aren't a pain :).

[Ichigo_the_demon_slayer]

well personally i think itd be cool if ichi became an arrancar and had those pwers to use against aizen or to use for the shinigami academy.

[Sandal Hat]

Too bad that he would have to go back in time and become a hollow first and then a shinigami to be able to become an arrancar

[Undying]

Too bad that he would have to go back in time and become a hollow first and then a shinigami to be able to become an arrancar
He'll need Urahara for that.

[Kuroshin Tenshi]

well personally i think itd be cool if ichi became an arrancar and had those pwers to use against aizen or to use for the shinigami academy.

I hope, that this is just your mistake. Ichigo cant' become an arrancar.
Because ichigo is a shinigami. So he can only become Vaizard.

[Undying]

He already is a Vaizard. He doesn't need to become one.

[Hollow_Man_ct]

also Arrancar and Vaizard are equal in power if the origins are equal in power, but you must know that Arrancars have an advantage on Vaizards, it is that they don't have an inner Hollow in the first place to deal with cause they already were Hollows, which makes the path of Vaizards the more difficult one, also the Vaizards would seem like the good guys in this contest, even though the Hollows tend to become shinigami along side their original position, they do it for the need for power and a building-size Zanpaktou ( However it didn't prove affective Vs. Isshin ^_^ ), so they will be eternally evil...

[demonbane91]

ichigo is neither an arrancar or a vaizard because he became a hollow and a shinigami at the same time during urahara's tests after ichigo's first encounter with byakuya and renji.

[davey062]

ichigo is neither an arrancar or a vaizard because he became a hollow and a shinigami at the same time during urahara's tests after ichigo's first encounter with byakuya and renji.


Ok, a vizard is a shinigami that entered the realm of the hollow
if ichigo hasn't entered the realm of the hollow, what do you call wichigo?

[Shinji]

I think you call Wichigo hollow but I don't know what you call their combination.

[Undying]

If we go by Zangetsu's clain that Ichigo already has perfectly developed Shinigami powers, then Ichigo's a Vaizard, because he had Shinigami powers and then became a Hollow.

[Ichigo_the_demon_slayer]

weel if he needs to become a hollow then why not let the inner one he has take over then go through it or if he really has to urahara could probably create a machine to travel back in time if really needed that badly.

but then that could be a filler episode ending in it all being a dream.

[Sandal Hat]

He'll need Urahara for that.

That's pretty obvious...:doindadom

Anywayz, I assume kubo wanted Ichigo to be a vaizard, even though the methods Ichigo used to become one were different. He has to do the same thing to control his hollow as the Vaizards and he has most of their characteristics

[Undying]

Well. given the new prespective the latest chapters gave us, I think that the Hollow actually wants the Shinigami it inhabits to grow stronger. Once you learn that, you use the help your Hollow offers you (by beting you to death), and grow stronger.

[Kyouka Suigetsu]

Hmm, I'm interested to know why Hichigo is doing this. Would be he weaker or stronger if he was the dominant personality? I think in order to reach his full potential it requires Ichigo's growth.

[Sandal Hat]

IMO he would be stronger if he put his hollow under his control since a Vaizard's dominant side is the Shinigami.

[Pazuzumaki]

I remember the vizards saying that if ichigo didn't learn to controll his hollow, then he would simply become a hollow and die a dogs death, or something like that, and that's what made Ichigo need to go ahead with the training. Btw, it seems to me that there is no question about ichigo being a vizard. He exhibits not a single hollow characteristic aside from those which the other vizards exhibit, or at least seem to recognise.

While it's part of the topic, are arancaru only the powerful hollows under Aizen's forces? I thought that's what it was, but then that raises a question: Arancaru is "to take off" in spanish, which obviously relates to the fact that they remove their masks, but then, does that mean that the natural vastroodes haven't taken their mask off?

[Kyouka Suigetsu]

That's assuming Ichigo is a Vaizard. We don't know this for sure yet.

[Zanga]

I'm also curious about the forbidden techniques to become a Vaizard. For some reason I doubt it is what Urahara made Ichigo go through making his 'world' nearly crumble and cuttin his sould chain thing. I really think there's more to it and that couldprove that Ichigo is truly a Vaizard.

[Undying]

Why so? If a person has completely developed Shiniagmi powers (i.e. once they awaken, he becomes a full Shinigami, as was with Ichigo), doesn't that classify him as a Shinigami? Then the Hollow appeared, thus making him into a Vaizard.

And Zanga, that was only because Ichigo needed his Shinigami power to awaken, so he made him go through that. Had Ichigo been a full fledged Shinigami, he wouldn't have had to go through his world crumbling.

does that mean that the natural vastroodes haven't taken their mask off?
I believe this answers your question:

[ShiNigamis_GoD]

I think aizen was quite trying to make a perfect vastoorode, that is why those arrancars who fought against hitsugaya, Matsumoto, Renji and Ikkaku were defeated, but remember that Ichigo Fought againts Grimmjow and didnt do much more damage after his Getsuga Tenshou so i think aizen made at least 10 Vastoorodes who exceeed captain's power

[kenshinsan]

Wikipedia explains everything perfectly.
But to make it short, there are gillians, ajuukas(didn't spell right), and vastroodes. They are all levels of menos. The gillians are the big dumb ones. The ajuukas are while smaller, are a lot more intellegent and stronger. Aizen implies that is the class that the Espada are made from. Then the vastroudes are the final class of menos. They look like humans and in their regular form are stronger than an average captain. Aizen hasn't gathered the vastroudes yet, thats why he says once they perfect the Espada(ajuukas turned into arrancars) and gathered the vastroudes they would take over.
So their can be. Non Arrancar Menos, Non Menos Arrrancar, and Menos Arrancar. With each class having their own strength.

Gillians Menos Arrancar(Shaw Long/Regular numbered 11 down arrancar) equal to vice-captain/weaker captains.

Ajuukas Menos Arrancar(Grim Jaw/Espada) equal to captains.

Vastroudes equal to the Extremely strong captain in regular form. Vastroude arrancar havent been made yet.(Such as the General of the 13 divisions.) Once again wikipedia explains it perfectly.

[Undying]

kenshinsan, I already explained it before...

Strange that everybody ignores me...

[kenshinsan]

Aizen hasn't made any arrancars from vastroudes though. From how he refers the Espada were made from Adjucha. When he said they need to find all the Vastroudes he refers that there are no Vastroude Arrancar. Grimjaw seems to be a Adjucha Arrancar. So you can't call the Espada Vastroude Arrancar.

Aizen Quote:After All they were only gillians. This wont affect our plans in any way. Once weve assembled the Vastroudes, and perfected the Espada...All those who stand in our way....will cease to exist.

By saying this you can conclude that since the only arrancars that died against the captains were gillians and they have yet to assemble the Vastroudes. The Espada were made from the Adjucha

[Undying]

There is nothing to suggest that there are no hybrid Vastorodes. It is perfectly assymabale that at least few of the Espada (at least, those numbered 3-0) are made from Vastorodes.

Aizen says that they must assemle the Vastorodes. But that can mean that they need to assemble those they have, or assemble those they do not have.

[kenshinsan]

Yeah youre right. You can't conclude that no vastroudes were made into Arrancars. That means that Aizen is hella strong to control all of them. If Aizen ever obtained hollow powers he would be unbeatable.

[Hollow_Man_ct]

He will and no he will be beatable, Ichigo must defeat him in order to end the Aizen arc, he can't just escape again, would be too lame..

[Undying]

No, he'll be unbeatable untill Ichigo beats him... typical Shounen Manga story.

[Shinji]

I really doubt he's unbeatable in spite of his powers because Ichigo will defeat him in the end!

[Ulquiorra]

ok so is ulquiorra made out of Vastoorodes because his helmet/mask looks like the shape of Vastoorodes:eek13:

[demonbane91]

i haven't read the manga but i think he may be a vastoorode arrancar.

[Kyouka Suigetsu]

Mask fragment shape has nothing to do with the true form of arrancar. Just take a look at Il Forte and you'll understand what I'm saying. Going from power level, I think it's possible that Ulquiorra is a vastoorode. I'm inclined to believe that he's a powerful Adjucha.

[Hollow_Man_ct]

WAS ( not is ) a powerful adjucha or WAS a vastoorode, but judging from his size, I'd say adjucha, but from power, definetly vastoorode, so we won't be sure till we see some more fights after Ichigo finishes his training...

[Undying]

Size after hybridezation means nothing, the Arrancars that came with Grimmjaw were all Gillians hyberdized (Menos Grande), and they looked like humans (though they seemed larger than normal humans, almost like Adjucha).

[Calenatarion]

Where can I find this information on vastroodes, vaizards etc?

[Zanga]

I'd say adjucha, but from power, definetly vastoorode,

He's strong for sure, but saying he's a level of a vastroode not really getting to me. During his arrival on earth with yami(i think it was that >_>) after Ichigo swifty cut yami's arm off, didn't Ilquiorra say something about Ichigo is a shinigami of his power once he gets serious, but is mere garbage when is helpless? Something around those lines.

[Reikkun]

ok so is ulquiorra made out of Vastoorodes because his helmet/mask looks like the shape of Vastoorodes:eek13:
IMO i think Ulq is and vastoorode, that beacause the his mask loks like the shadow of the vastoorode shown when Hitsu was explaning things to ichigo. but like it have been said theres no other clue about it.

[Hollow_Man_ct]

didn't Ilquiorra say something about Ichigo is a shinigami of his power once he gets serious, but is mere garbage when is helpless? Something around those lines.

nice point Zanga but remember that nobody said that Ichigo is not stronger than the Espada, he may as well be stronger than Grimmjow at his height as well, cause Ichigo was FAR from being serious or fighting for a cause when he faced Grimm + he had troubles with HIchigo, so Ichigo > Ulquiorra > Grimmjow, IMO.

[grimm_fans]

That's true since grimjaw got his arm cut off by tousen which means he is very weak

[ppm]

Aizen could be defeated in various ways

As he said, any1 who saw his zanpaktou released will be hypnotised

So u either kill him b4 he release his sword or

otherwise unable to see him released his sword

1st: Tousen
2nd: People that are not there to see his released zanpaktou

As for 1st situation, Maybe Tousen is just a traitor waiting for a chance to stop all killing at once including killing aizen and when the time is ripe he would do it

And the 2nd situation would be, Ganging on him, At different times and when he released his sword only the 1 whos seen it will be under his hypnotism but those that didnt see it engaes him now then would be affected by his hypnotism

[Ulquiorra]

can tousen even get hypnotised ? since hes blind , he can sense stuff

[Zanga]

Hypnotism doesn't always be done with sight. There is emotional hypnotsim. Hinamori thinking Hitsugaya was the murderer of Aizen was one of them. She was hypnotized by Aizen's kindess and what not.

Tousen could be brought into believing Aizen can make a better world with the power he will gain, which could say he will gain the power of a god.

[Ulquiorra]

so ur saying aizen has no weakness ?

[Zanga]

No I'm trying to say that Aizen doesn't always need his zanpaktou to hypnotize, and Tousen might be blind, but is still very able of being hypnotized.

[Kabane]

well through his zanpakuto anyways, aizen states that you are only under hypnosis when you see his zanpakuto being released. Naturally, since most if not all zanpakutos compliment a shinigami's personality, Aizen is a manipulater himself, thus he tricked Tousen, so to speak, that his way is for the better.

[ppm]

In the manga, Aizen already said the only 1 possible way not to get hypnotised is tousen because he is blind and seeing his zanpaktou released is the key to his hypnotism and he added he has already made tousen his underling from he start.(go and read the conversation between aizen and unohana again)

But another point is Tousen may be still vulnerable to Aizen because Aizen's bankai is not known yet

[Hollow_Man_ct]

Tousen is untouchable by Aizen's Hypnosis, Tousen thinks by Aizen's clever and convincing talk that his path is the least with blood shed, so Aizen didn't Hyponotize Tousen emotionally or such, he convinced him by mere talk.

[Zanga]

During that mere talk Aizen could've triggered the memories of Tousen's deceased friend and the belief that this world does not have enough justice hittting him emotionally.

[Ulquiorra]

Tousen is untouchable by Aizen's Hypnosis, Tousen thinks by Aizen's clever and convincing talk that his path is the least with blood shed, so Aizen didn't Hyponotize Tousen emotionally or such, he convinced him by mere talk.

ya thats wut im thinking.

Aizen : i will give u justice

Tousen : yes i love justice~

hand justice over to tousen *

Aizen : work with me and i will give u more justice

Tousen : yes aizen-sama <3
