Minus Retro, aka Metro encountered Boyfriend when BF somehow appeared in the sports field where Metro was, Metro is also quite bad when it comes to saying some words and can easily get mad if corrected, he even thinks English is stupid. If Metro becomes really mad then expect him to throw a football at your crotch, if that does happen then going to the hospital wouldn't be a nice trip. He also tends to have a short-fuse like his normal counterpart, Retro.
