The Elmo Gang was formed by Elmo after the events of Grand Theft Sesame Street when Elmo was struck by lightning and turned evil. Him and his fellow Muppets (half moron, half puppet) joined together to rule the world Sesame Street! Elmo's gang was originally headed by its namesake, with Grover and Big Bird being the only losers in it. Big Bird was kicked out three seconds in (his own fault). Grover remained longer, but was killed by Elmo. Slowly, more muppets joined the gang.
