Kenpachi is supposed to be a powerhouse; a blood-thirsty demon. He's even listed as a Special War Power specifically for his fighting skill. Yet in this arc alone, he's been put into a comatose state four times now (three of which occurred in less than a hundred chapters). No one will think of him the same way again.

Perhaps "ruined forever" was hyperbole. I meant his character development and whatnot felt like a wasted opportunity. Regaining his true power, gaining his true Shikai, he should've been unstoppable. At least that's what was insinuated. He should've been able to take on Gerard without Bankai, and only take his eye-patch off as a last resort. But he magically acquired Bankai, wrecked Gerard and eventually cleaved him in two, and Gerard is still alive.

Seriously, what was the point of killing off Unohana for an increase in Kenpachi's power, and even giving him Bankai if it didn't freaking amount to anything?
