Rainbow Charizard

Something so rare it needs to be considered at a higher price..
For example a down syndrome chinaman or a black guy with a tiny dick.

Wing Chung Ho was a rainbow charizard, his X and his Y didn't quite add up.

Rainbow Six Siege

Pain, pure uninterrupted pain. Ending it all is a significantly more enjoyable, viable, and possible experience than an enjoyable game of R6
