Hmm.... that last thing you said bout the 'main guy' gave me an idea. He could just be that 'nameless boss' that everyone just refers to as 'boss', and no one knows his name for some reason, and never thought to actually ask. I just noticed, neither of your characters, and none of mine asked... so, that seems to work best. xD

As for the scientist... IDK. Could be anything really. Hmm... we need to think of a good country for him to be from. Probably some country where he'd be even shorter than Japenese dudes. Oh, Indonesia? xD. He'd be puny and angry! xD
