Kenpachi Zaraki

Kenpachi Zaraki is widely considered the best fighter in Soul Society. He attained his position as Captain of Squad 11 by passing the third method of qualifying for as Captain - kill the previous Captain in fair, 1-on-1 combat in front of their division.

After this, Kenpachi has devoted his time and energy to finding and fighting stronger opponents and increasing his own power. However, he also limits his own power in battle, only increasing it when he feels like his opponent is strong enough.
