wow, your oc is a magnetic-mecha thats not easy a thing to find in the internet. i recall only some marvel comic and japanese turn based adventure game featuring such personages. im gonna follow you to see what become of your oc. you catched my curiosity.
(no way in heaven that i can pin-point you the corect marvel book im refering to, but the game i talked about is called 'enchanted arm' i think its a 360 only game though. it wasnt very popular and have a unnessesary complicated story)
