Sun Wukong

The Monkey King is a physically unattractive primate, possessing golden fur and wearing golden armor adorned with red and turquoise fabrics; he has a peach-colored mark on his face in the shape of an inverted heart, and another one in the shape of a little heart on his chest

The Monkey King has many enemies, although some were and/or became friends over time
their main social circle ends up being:
MK, Aka: de Monkie Kid
Mei: the reincarnation of the white horse dragon
Piggsy: the reincarnation of Zhu Bajie
Sandy: the reincarnation of Bonzo Sha
Tang: the reincarnation of the monk Tang Sanzang

He has acquaintances who are somewhere in the middle.
The six-eared Macaque: His former companion in adventure, whom he murdered thousands of years ago, was brought back to life once more by the work of a powerful demon, but they managed to make peace, in a way.
the Demon Bull King family: formed by the union of the Demon Bull King and his wife Princess Iron Fan, who had a son named Redson, The relationship with them is complicated, thanks to the fact that they are a family of villains and Wukong had to seal Demon Bull King under a mountain for centuries, ultimately for personal gain of course, They reached some kind of peace

He is the Monkey King from the story: Journey to the West
His personality can be described as that of a man in his 50s who knows he has lived too long and regrets everything he has done in his life but refuses to accept that guilt, taking refuge in childish and almost stupid attitudes in the hope that the mistakes will not be repeated and that the past will not catch up with him soon thanks to his immortal existence

He tends to be impulsive and childish, despite being the teacher of the local hero, the monkey boy; He is usually seen wandering and loitering around his island, Flower-Fruit Mountain, Since he is no longer the possessor of the golden staff of his legend, his life has been reduced to existing infinitely without anything more, completely isolating himself from the outside world, his only interactions revolve around giving lessons to his student or accompanying him on adventures when needed; beyond that, he does nothing else but exist, probably in pain
