OTHAR
Othar is the Hero, of course. He is brave and dashing, and ready to take on any villain, any time.
As the Hero, it's natural for him to have sidekicks, and he does. They do have a disturbing tendency to die in villainous traps or just leave after a while, but he knows another sidekick will always come along.
He is a hero with a mission, just like the Heterodyne Boys. He is on a mission to liberate the world from the tyranny of Evil Sparks.
Heroes don't commit "murder" or "genocide". Heroes Save the Day… by any means necessary.
