Like is a Sage (For context, sages refer to people who made the universes.)
He grew to dislike his brothers due to the fact how they do not see non-sages as people, but mere puppets for their show, along with Fred(Oldest)'s attitude to them and JBear(Middle)'s pure chaos.
As of which they are part of the 3 alignments, Fred being lawful, JBear being chaos and himself being neutral.
He decided to abandon them, since after all they have each other to bring balance so he decides to live among others, since it was no fun being stuck with his brothers.
He kept his powers a secret such as his ability to create rifts which all of his brothers can do and his natural ability to both use masks for power and manipulate emotions, he still refuses to use this on people unless it fits his motive.
His "mortal" backstory depends obviously, but from what he's known as, he has his own arcade area in which he makes his own arcade machine games so they're unique to his only.
He is neither good nor evil. Same with his secret motives, they can be argued as good or bad, but in the end he seeks balance so if he needs to become evil, he will do so. If he needs to be good, he'll also do so.
So to break it down:
His backstory was created in mind as a character, not a fursona so I really don't see myself in his shoes other than when he's with mortals. He was just heavily inspired by some of my past.
He his the middle of the universe, not good and not evil, but will switch if needed.
He actually cares about the people enough to be willing to live among them, but not too much to want to convince his brothers otherwise.
His powers technically allow him to create a universe on his own, or even to destroy it, etc but he does not abuse such power.
