??? is an evil guy and a pro-hacker. He is friends with SMG3 and helps him destroy Mario and SMG4. He is SMG4's oldest foe. It was thought that the true identity of ??? was SMG3 himself but this was proven false, he is a friend of Drill Finger as well. He has a twin brother called the Bomber who tried bombing the Mushroom City and a twin cousin called the Crazy Toilet Dude who is obsessed with his Toilet and thinks it's a living thing.
