Ryuujin Jakka (Flowing Blade Like Flame--thanks to [info]lacewood for this)
Owner: Yamamoto Genryuusai Shigekuni, Captain of the 1st Division and Captain-General of the Shinigami
Command Phrases: "Banshou issai kaijin to nase!" ("Reduce all creation to ash!")
Abilities: Ryuujin Jakka is just plain unfair. In its activated form, its blade is engulfed in an aura of fire. Anything the blade passes over or touches is reduced to ashes--it's just that goddamn hot. When Yamamoto first fires the thing up, the mere act of waving it around a few times soon has the surrounding area completely consumed by flames.(Props to Myname for this as it isn't my work but what I put will b lol changed one word though the English dubbed version says Reduce is y I put it.)
Bankai: Zanka no Tachi
Bankai Abilities: Zanka no Tachi's abilities are limited by the points of a compass. The 4 different attacks it can do are as follows
Zanka no Tachi, East. Kyokujitsujin(Name not translated yet any translation would b helpful.): Pours the power of Captain Yamas flames on the edge of his blade.
Zanka no Tachi, West. Zanjitsu Gokui (Translated: Prison uniform of the remaining Sun): makes an impenetrable defense of powerful flames that will destroy any sword that touches it even the Quency arrows are of no use to this power.
Zanka no Tachi, South. Kaka Juuman' Okushi Daisoujun (Translation: Great Army of 10,000,000,000,000 Buried by the Flames): Creates a vast army of undead that were killed by the head captain to annihilate his foes.
Zanka no Tachi, North. Tenchi Kaijin (Translated: Heaven and Earth are burned to ashes.): Unknown
Zabimaru
Owner: Renji Abarai
Shiki command: Growl, Zabimaru
Bankai: 1st form Hihio Zabimaru (Translated: Baboon King Snake Tale)
True form Soo Zabimaru (Translated: Twin King Snake Tale)
Bankai look: With Hihio Zabimaru it is just one complete piece makeing the sword bigger and the sword become a snake with the sword becomeing snakelike and moveing the way Renji makes his arm move on his left shoulder is the skull of a monkey and the top portion of his body has a red fur around his shoulders.
On the other hand with Soo Zabimaru his form is totally different with one of his arms he uses Hihio and the other has a monkey skull and blade which is called Orochio. Basically Hihio becomes an extension of his left hand sort of like a guard while Orochio is the blade on his other hand and the power is increased by I would guess 10x its original power
Sode no Shirayuki
Owner: Rukia Kuchki
Shikai comand: Dance, Sode no Shirayuki
Bankai: Hakka no Togame
Bankai Abilities: Able to freeze anything to below Zero temps. Only bad side effect of this Bankai is Rukia has to warm her body up slowly or else she could end up killing herself useing it.
Give me a buzz if I forgot anything as those r the ones I wanted to put out their as no one ever figured out that Renji's real bankai as it seems no one reads the comics anymore lol as well as for Head Captain Genryusi Yamamoto Bankai hope u guys enjoy and also give the props to the comic as it helped me a bit to get the translations of some of old man Yamas Bankai you can read it at this web adress :
