The main protagonist and the second known monster/human hybrid.
Chet (human): This was the personality that had been using the body completely until it changed. Chet originally appeared human and he mainly had features from his mom, Monique. The only thing that really stood out about Chet was his SOUL. It was upside-down like a monster SOUL, but it at the same time, it had a trait of DETERMINATION (which was also uncommon). Despite this, Chet would grow normally until he reached the age of 18. At that point, his body underwent changes as he slowly but surely started to look more like his estranged dad, Remulos. When the transformation was finished, Chet freaked out and demanded answers from his mom who told him that he was half monster and that his dad was a monster. This deeply shocked Chet and he asked why his dad had left. Unlike the other times, Monique gave him answer. It was because the elders of the monster lands had forced Monique to leave w/ Chet for they feared that history would repeat itself and what happened to the previous hybrid would happen again. Chet asked what happened to the last one, but his mom didn't know. Chet eventually moved out of the house and struck out on his own. He became a freelancer, tackling different odd jobs for money. His most consistent clients ended up being Pudding's parents, Charlie and Martha as well as a robot mechanic w/ a TV for a head named Patricia. Another frequent job was capturing the tiger soldier girl, Cindy, and stopping her from causing to much damage (this does spark a sort of frenemy rivalry between the two). Chet would also later find Mort and was forced to be his Master. Chet (frustratingly) tries to help Mort became more of an individual. Progress w/ that is very limited and slow but it's working nonetheless. This Chet is sarcastic, lazy, a decent guy, and is usually pretty calm and level-headed.
Chet (monster): The other personality that Chet has inside him. This personality mostly stayed quiet during Chet's childhood. During his teenage years, this personality started to try appearing to human Chet in their thoughts but human Chet mainly just blocked him out and chocked it up to him hearing things. When Chet transformed however, the monster Chet then was basically like "F**k it" and he sometimes forcefully switches control away from human Chet. This Chet is the opposite of the first one. He can be pretty aggressive, energetic, a real prankster, and has a soft spot for soft sweets (particularly sherbert ice cream). He loves f**king w/ human Chet by switching out at the worst times and basically saying something that human Chet didn't want to say. He's also kind of hateful towards his human half for trying to repress him and ignoring him when they were teens.
These two do come to an understanding and they do work something out (they even learn how to work together in battle and switch on the fly).
Their weapons are: SOUL daggers and their claws as well as pretty good strength and speed. They can also use blue SOUL magic to manipulate their opponent's SOUL.
Pet: Kurt the Mochii Monster. He likes both Chets, but he actually prefers the monster one.
Megalovanias:
