Dragonslayer

A secondary villain from a niche, cheap, 90s JRPG who got summoned into the world by otaku trying to summon the princess heroine from series.

He has an unpredictable personality and strong mood swings, he distrusts almost everyone but is eager to gain power and influence in any kind of group he's in, so he sometimes tries to have a non-hostile relationship with his fellow villains.

Any armor detail can be simplified, and his eyepatch and scars can be on either side of his face.
