Main

 * Kai - the hyperactive yet both cocky and determined son of the Monster King who after being only seen as a weak link by his father, heads on a quest to become strong enough to beat him, slowly gaining more and more strength to prove himself to his father, being rather connected to fire itself, using it for most of his attacks.
 * Silver - a cynical and focused monster slayer who wants to prove himself as the best, reluctantly being convinced by Kai to join him due to Kai needing partners to help him train. He wields a blade and is extremely agile.
 * Cora - a rather bubbly snake-like monster girl who wants to train herself to be the best, encountering Kai and becoming a more friendly rival to him, wanting to train herself to be hopefully as strong as him.
 * Shard - a small flying furry monster who despite refusing to fight, is a skilled medic, having been the Monster King's medic as he decides to join Kai so he doesn't get too hurt in his quest.
 * Grog - a wise yet strong ogre who was heralded as one of the best warriors as Kai found him and convinced him to be his trainer, joining him due to believing that training through adversity is the best way to grow stronger.

Supporting

 * Amon - the cold and ruthless king of the monsters and Kai's father who only sees worth in those who are strong, having neglected his son and is primarily focused on ruling the monsters, however it is revealed he somewhat cares for his son.
 * Jacques - a lobster monster who is the head chef of Amon as he is surprisingly good at cooking food, his meals being considered to be among the best food out there, although he can be insane at times.
 * TBD
 * Kuma - a wrestling bear monster who had temporally gone mad, going on a rampage as he ends up being defeated by Kai, being convinced to calm down and continue his wrestling career.

Antagonists

 * Ikari - a psychopathic monster who used to be one of Amon's trusted generals as he was exiled for his cruel treatment towards humans, now wanting to overthrow Amon with an army of loyalist monsters, being able to grow stronger the more hatred he feels.
 * Gold - Silver's emotionally abusive father who absolutely despises monsters and helped mold Silver into a monster hunter as he begins going way too far, hunting after monsters that have done nothing long and soon cybernetically enhancing himself as he now wants to kill both Kai and Silver, who he sees as a traitor.
 * Nikolai - a calm yet terrifying vampire who is a significantly stronger fighter during the night as he wants to create an eternal night so nobody would be able to stop him and his takeover of all monsters.
 * Callisto - a bloodthirsty spirit of vengeance and hatred who leads her two sisters on a quest to slay all humans after learning of the destruction and terror they cause to monster kind, soon clashing with Kai due to his love of humans.
 * Eyris - Callisto's childish and playful sister who really enjoys playing with her victims and often throws a fit when things don't go her way.
 * Alazora - Callisto's cynical and gloomy sister who finds humans to be weak and pathetic and believes that she is way better than them.
