Leader
Even though he is the youngest – younger even than Jakotsu – they all accept Bankotsu as their leader. He is not as smart as Renkotsu, or as strong as Kyokotsu, and he doesn't have the machinery tricks of Ginkotsu or the Mukotsu's poisons.
All he has on his side is strength, courage, and Banryu.
Every once in awhile, he'll look at his comrades, and he'll wonder why they constantly follow him, why they obey his orders without question. Renkotsu would make a better leader, they think – he is the most intelligent, the most cunning, and he is always the one who fine-tunes their plans.
But they look to him, and he nearly constantly wonders why. Granted, Renkotsu's ruthless, and if it came to his own hide or that of his comrades, he'd choose his own every time. Kyokotsu couldn't think his way out of a box, even one with a door and an exit sign, despite his size and strength. Mukotsu's is too flighty, too concerned with finding a woman who wouldn't care that he's so damn ugly. Ginkotsu…is a special case; not that he's stupid, although he is, although Bankotsu thinks if he had that much metal in his head he probably wouldn't be too smart anymore, either. Suikotsu has the weak-sister doctor in his head, constantly haranguing him about the people he kills. And Jakotsu…the very thought makes Bankotsu shudder. Jakotsu is a girl, really, and who would follow a girl? He is more concerned about his appearance than any real show of strength or solidarity.
It is Bankotsu they trust not to abandon them, Bankotsu they trust to keep them alive, and Bankotsu they trust to lead them.
As he looks around at his comrades, shortly after their resurrection, he realizes it's because he's the only sane one there.
End
A/N – Bankotsu's kinda cool, isn't he? And he really is the only sane one out of that bunch.
