your headcanons of him is also appreciated 
i am going to assume this was about jeser and so i will answer using him.
-He was taken in very early on. Very much to his demise. hes been a hater since day one.
-was originally a jester for the court. also to his demise but he had a little fun with it, but like the little freak he is, wanted more power.
-this is where his name comes from. he originally didnt really have a name but was given a name similar to ‘jester’ aka jeser. he hates his clown days tho. quite shamful for him. but doesnt mind the name.
-he gained the title “prince of many faces” later on. When he was higher in ranks. only gained the title prince bc the people under the kings rule knew he would be a heir. not by the kings will, but just that if the scarlet king were to perish like jeser planned, he would take over by force. The “of many faces” coming from his ability to shapeshift. but also in a metaphorical sense since he is a trickster and will manipulate.
-he would OFTEN use his ability to shapeshift to trick others or stir up stuff. he is the drama queen of the abyss. gets too bored if drama isnt happening.
-he doesn’t really like to meddle in human life, or with earth at all. Only bc he cant destroy it or do what he wants with it. He just messes with whats given to him. But he does know a bit about human culture through the scarlet king and molochs limited knowledge.
-him and moloch besties. 4lyfers. was devastated when he died. the only death he was ever devastated about. lets say worlds and people were NOT spared.
-never really got to know who killed him, but if he did trust he would be after them. SK never told him either cause he didnt want to lose another “ally” and also, just didnt care to tell.
-Bonus Alagadda thing: he has been to alagadda with the king, but does not really care about it. He also cant do anything with that world either due to the treaty of flesh and thorns, so it just isnt important to him.
basically if he cannot do what he wants with someone or something, he just does not care about it, unless it is someone who will get in his way of staying at the top, then trust he will weasel his way to put them down.
