Glitch Mario- The Glitch version of Shadow Mario, however, he was not Bowser Jr. as Jr. somehow managed to create this entity in an unknown way. Shadow Mario entered in from The Mushroom Kingdom through the Grid, and was soon unexpectedly infected by the T.A.B.U.U Virus, and was transformed into Glitch Mario. *SPOILER* Glitch Mario had an early encounter with the User Program Mario, and initiated a battle. However, in the end it was a tie and each went their own way. Glitch Mario is currently moving through the system, painting M marks with viral pain wherever he sees fit, and is waiting to once again encounter his User Program twin.
