Monster

backstory
he was born from a gigantic fire in demon land (yeah i named it demon land i am creative) and then 1,236 years later he was accidentally summoned by jared during a potion-making class and now hes just..... on earth

he originally wanted to go to earth anyway because a couple months before jared unintentionally summoned him, his sister decided to leave demon land and since hes stubborn as hell (pun intended) he didn't go,,,,, but then he wanted to go so now he is there

fire
he has fire magic (ranged magic, creation type) he has a weaker form of it than his sister, though, and can't do stuff like coat his entire body with it cause yea. also since he is a fire mage, fire doesn't hurt him

wings
according to all known laws of aviation, there is no way monster should be able to fly. his wings are too small to get his fat little body off the ground. monster, of course, flies anyway because he is a menace to society.

teeth + claws
he has unusually long claws which are retractable and he also has retractable (top) fangs. almost everyone has animalistic teeth and claws because almost every character is a furry or has at least some animal-like characteristic

personality
he's honestly just....... really destructive chaos gremlin????? also he's loud (he can do the mic spam effect with his voice) and hes very stubborn. he also tends to have possessive/manipulative tendencies
