Thus Metal Mettle was designed from the beginning with his powers in mind. Add the fact that he was fun to play, and he became my "main". He is the only character of mine who ran enough incarnate content to achieve the coveted "50 (+3)" rank.
I had already created several characters whose names were homonyms. (Heck, later I even created "Diddle Diddle", after the nursery rhyme! Yes, I'm sort of a nerd.) Metal Mettle wasn't my first robot, but he's the best looking.
