Emerl

Emerl is the adoptive son of Sonic and Sally and Metallix's Keyblade successor.
==Appearance==
Emerl is a humanoid, mostly mustard-yellow, robot. He possesses five-fingered olive-brown hands and feet in the shape of shoes with orange soles. His upper arms, abdomen and thighs are olive-brown, and he has spherical orange joints as shoulders and pelvis-legs joints. He also has relatively thick armor around his forearms and lower legs (each one possessing orange cuffs), thick kneecaps, and some kind of jetpack on his back. On his chest, he has three beige circles. Lastly, he possesses a spherical head with a beige mouth plate, blue eyes, orange caps for ears, and a curved orange horn with a concealed blue eye on it on his forehead which opens when Emerl transforms into Ultima Emerl.
Various forms give some changes: his form when fighting Xemnas in Wonderland has olive-brown wings; in Agrabah, Emerl gained four arms. His monstruous form that he takes when he absorbs Xemnas' Kingdom Hearts resembles Ansem's World of Chaos.
