Fatal’s new form (it’ll be soon, but I’ll let you meet Christine and Corrupt (the 2 other heads))

Corrupt is the most dangerous of the trio, being deadly with any slight inconvenience, he's the red circle with the ghost.

Christine is the Blue, Yellow and pink shine, being sort of like Toriel, but more kinder and more known to giving people second chances.

Fatal is the original one, the red shine. He's just like himself except way taller.

(This is based on u/Dearfuse's OC Cyan being gigantic, but all 3 can take control at any moment)
