Kon

A 'Mod Soul' that escaped destruction: when Ichigo leaves his body to fight, Kon takes his place in it. The rest of the time he lives inside a stuffed lion.

Mod Souls were created to reanimate corpses in battle, then banned: Kon was meant to be destroyed and ends up in Urahara's dispenser by mistake. With his enhanced legs and boisterous personality, he is Ichigo's comic sidekick and Yuzu's favourite victim, dressed up like a doll.
