"Beware the knight in vantablack armor."
The leader of the Unknown World trio. Tobias used to be a normal guy, but what happened was that one day, he was walking when he noticed someone getting harassed by demons. He stepped in and got the poor fellow out of there, but as punishment for spoiling their fun, the demons took Tobias and used their dark magic to turn him into a suit of armor. After this, having had their fun, the demons cast him onto the streets. From this moment on, however, he swore vengeance against all demons for ruining him and for terrorizing others.
Tobias mainly uses a bloodred double-sided axe to attack people and, despite what he is, he's surprisingly nimble and quick on his feet. As for his teammates, he didn't plan on having a team in the first place, but he unintentionally created one when Asterick refused to stop following him like a lost puppy and when Kharan refused to stop pestering and following as well. The trio mainly goes around like the 3 musketeers; righting wrongs and slaying demons (and getting caught up in hijinks along the way).
Fun Fact: Being turned into armor isn't the only reason Tobias hates demons. Another reason for it is because he's empty. He constantly feels empty and he needs someone to fill him, but he doesn't want to push the issue because once someone goes in they can't get out.
P.S. Yes, I did get quite a bit of inspiration from Fullmetal Alchemist w/ this one. Also, the crest on Tobias' head is a reference to Golurk from Pokemon, the coloring was somewhat inspired by Black Knight from Shovel Knight, and the arms and face hole are somewhat based off of the arms and face of Micah by  burntbeebs.
P.S.S. This is definitely one design that I'm really happy w/ btw.
