Why is jax charachter (a bunny) is related to him?

You see we got pomni=jester: kinda like the punching bag of everyone, zooble=toy with removable parts: having struggle with indentidy, ragatha=ragdoll: Probably let people step over her and treat her badly but she tries to treat them good, gangle=mask theaters: Masking her saddnes with the happy mask and kinger=king: Cause he is a mf king. But jax a bunny?? I dont really know how it connects to him.
