Monster Kingdomball

Monster Kingdomball or Undergroundball is a countryball from the game undertale. He was formed after a war between the humans and the monsters in which he was sealed into the underground by a magic spell because of humans. He stayed there in the underground ever since. He can be friendly to humans sometimes but other times he would try to capture and maybe even kill humans for their souls in order to free himself from the barrier.

History
Long ago there were two races, humans and monsters, then they had a war and the monsters got sealed into the underground by humans with a magic spell creating the barrier. Since then Monster Kingdomball was born, at first he liked humans so when the first human fell, he took care of him but the human died because he didn't realize that buttercups were poisonous to humans. So Asriel who's the king's son absorbed the soul of the first human and went to the human world. But the humans didn't like monsters so they killed Asriel. Afterwards Monster Kingdomball hated humans ever since and decided to kill all humans and use their souls to break the barrier finally although he was kind of stupid as he literally waited for 7 other humans to fall instead of just getting 1 soul and crossing the barrier to kill 6 others. After 6 humans fell and killed them, he got reset multiple times by this stupid flower who's actually Asriel before another human fell and now the human is the one resetting him over and over.

Personality
Monster Kingdomball is very chill and usually likes to hang out with others, although he sometimes has an existential crisis due to being resetted multiple times. He has a little bit of time awareness and can sometimes be aware if someone was messing with the timelines. Monster Kingdomball can sometimes be hostile to any countryball that's majority human and will try to capture them sometimes. Nevertheless once a countryball gets to know him he's very friendly and likes to do fun things with other countryballs and makes puns from here and there.
