Luigi was a member of The Super Smash Brotherhood and was the brother of his leader Mario, as well as his right-hand. He was discovered with his teammates by Darth Squidward. Their organization was to be all Male but Samus blew it. Eventually Darth Vader and his stormtroopers killed all the members except Pikachu. Luigi was gunned down by the stormies, the last to die before Mario himself.
After his death, a strange Luigi-like spectre named "Weegee" began haunting the HoloNet, mesmerizing people with his blank stare. In an attempt to both counter Weegee's destructive powers and bring back the original Luigi, SpongeBob Squarepants created a bastard clone known only as "Mama Luigi", who still survives to this day. In the real world.
