SuperLuigiGlitchy4 is the long lost brother of SMG4 and SMG2. He is somewhat evil and was a friend of SMG3. He worked with SMG3 for years and tried to overthrow Mario, SMG4, and SMG2 but failed and was killed as a result. SLG4 makes appearances in the Longplays too despite his apparent death however this may be the color code used for just a random person, it's unconfirmed as of now.
