Yachiru Kusajishi

Spoiler Alert - if you don't wanna be Bleach spoiled about Yachiru, I recommend you read this page very carefully. Also, Yachiru is dangerous.

Yachiru Kusajishi is the lieutenant and adoptive daughter of Kenpachi Zaraki, who is a War Potential, according to the evil Quincy. She is also the president of the SWA. The Bleach Wiki says more stuff abou that if you want more details being provided.

About
Yachiru is a pink-haired girl who likes to call people by the nicknames she creates in like 2 seconds (or even les; she's fast!), including the Captain. She is stronger than all of the other lieutenants with her pink reiatsu, that matches her hair. According to and old man created by another kid's imagination, Yachiru has wild features, like a monkey. She thinks that bones can be used as hairpins and used to be unaware of blood and swords when she was a crawling baby. Yachiru's name comes from another Shinigami.

Powers
Yachiru punches everything that appears around if she thinks that it's an enemy. Be careful around her! And her zanpakuto might activate without your notice! And you might be cut. She also has the power to drag you into wrong directions inside a maze. Or in Soul Society. Her sense of direction is terrible! But i'm listing this as an ability. She is also a nickname specialist. And some of you guys might find her adorable. She is strong, fast, sturdy and is an "infiltration expert", whatever that is. She is also able to identify Ryoka judging them by their Reiatsu. Speaking of Reiatsu, Yachiru is overflooding with that.

Nicknames
Perhaps one of Yachiru's best characteristics is name improvisation. If she were a Quincy, her epithet would be N for "The Nickname", certainly. Here's a list of nicknames she invents.
