Max Minner unmasked

Max unmasked.

To destroy each other's businesses, they dressed as Humungonauts, going on a rampage on the property's the other supported, with Max as the Green Humungonaut.

When it came to a dock that Mystery Incorporated set a trap for, the Green Humungounaut ended up fighting the Red Humungonaut until they both easily got caught in Fred Jones, Jr.'s trap. When Sheriff Bronson Stone and Mayor Fred Jones, Sr. arrived with the cops, Velma unmasked the Humungounauts as Max and Jax Minner. After their backstory, Max and Jax stated that they would've got away with it to "if it weren't for my meddling brother." This caused the brothers to fight again as two police officers tried to break it up.
