the ultimate meme destroyer. Or UMD for short is a celestial-multiversal being. He is about the size of a solar system. Or a big building...he can use deadly sound waves to kill his opponents and those soundwaves are the rickroll song. He has defeated both super sanic, god weegee and has fought the entire meme team. And he only died to GabeN's half life 3 attack. The UMD is a force to be reckoned with, and even survived the morshua nuke, he exist to serve balance to the universe.....
