[🌀]【Exeller】[🩸]

He looks just like Sonic (because he owns him!)
blue humanoid hedgehog
red sneakers with a white ribbon in the middle of each one
Black eyes with red irises and black pupils (sometimes they bleed)
light-colored muzzle, along with the inside of his ears and the center of his chest and stomach

AND HE'S A MAN 🫵

Exeller used to be an arcane hedgehog, belonging to the third class and befriending Alice, a first-class rabbit. Thanks to his spirit of destiny, Exeller would discover that he actually belonged to the Zero class and that his memory was erased so that he couldn't use his power.

Exeller, after discovering his hidden powers, killed his destiny spirit and began to enjoy making others suffer, which led him to kill the King, Alice's father. However, Exeller was killed, and his spirit traveled to Mobius, where it took control of Sonic's body.

Alice is her old friend
(but according to the lore, and apparently they share the same soul, she could be his "sister" for that reason)

Sonic is basically a ghost now, barely able to control his body because of Exeller, and even arguing with him quite a bit due to the events.
