Why am I not surprised that I put these two first as the character when the silimarities are bloody endless.

The colour red is very apporiate and very easy to use as a colour way for the background. The characters have a strange liking for red on their attire. Especially when Rev Runner unclothed is blue (and the early designs for Loonatics Unleashed made his costume blue; but really red suits him better).

They're both really sound the same; well in the English versions they're do. If Rev's slightly slow down his speech it sounds a lot like Raphael. I really don't know much about VA's; so I betcha they're probably the same VA anyway.

Rev and Raphael both get slightly irritated easily at small things. They're can chatter, both have some really good lines. Plus other things. ^_^ Too many.
