I so love browsing Zangetsu 747's post on creating your Zanpakuto. However, as we all charge blindly into posting the powers of our original self-thought Weapons of Mass Pwnage for the masses to see and drool over and thus ad their own ideas, we all forget one thing:
Zanpakutos all have a spirit dwelling inside them, and that they have feelings, thoughts and desires of their own.
Which is why Yumichika and Rangiku can't achieve Bankai just yet due to the hindrance of their zanpakuto spirits (one is vain and the other is lazy - im not talkin about the shinigami themselves), and that Zangetsu hurled Ogichi at Ichigo in between the fight with Zaraki Kenpachi to test his resolve and trust in his Zanpakuto. Did I forget mentioning that Kenpachi can't achieve Shikai, much less Bankai, since his Zanpakuto spirit hates his guts?
And thus I decide to post up this 'create your zanpakuto's spirit' post. I know it isn't going to be as popular as 'create your zanpakuto' since you can hardly use your spirit in a real combat, but you gotta respect and trust them absolutely if they will even grant you the capability to go BAAAANKAAIIII!!!
And heres my Zanpakuto spirit of my Black Spider (found in Zangetsu747's post pages 8 with edits in 9 and 10)!
Appearance: Very big, about 8 feet tall. Completely black-skinned, well muscled cross between a man and a spider, where he has the body structure of a man, but waist-down his body is compromised of two long spindly legs and two much more human-looking legs that end in a single spike-like foot where the tip touches the floor, and his arm joints have another pair of monstrous arms protruding out of them along with more human-like arms. Spirit is capable of folding spider-y appendages inwards to hide them along with shifting some bones in front legs to gain a completely human stature.
Spirit has a cloak of pure, solidified darkness that covers most of his features, but sometimes one can roughly guess his appearance through the cloak. Spirit is faceless, and there is a noticeable pattern of white-lines all over his body that form a web-pattern that shines through his cloak at all times. Capable of speech despite facelessness, where his voice seemingly vibrates all over the dark forest that is my original character-his master's world.
Personality: Very courteous and enjoys conversations with master, but when talking, sentences tend to have an icy, poison-laced accent behind them. When speaking to character in the inner world, the spirit prefers to talk to him hidden in the trees or behind the character. Always reminds the character not to be comlacent with his power, and to always seek new heights of martial prowess.
Character must talk to this shadowy being to discuss new weapon forms for the zanpakuto shikai's shape-shifting ability, for trying to suddenly form a new weapon without prior planning out of the shikai's blade segments in a sudden frequently ends in failure, but once the new weapon form's shape is agreed upon the character can form it instantly without fail in future battles.
