Several Sklugg appeared in Breach's pocket dimension, where she liked to watch them fight. After they were defeated by Rex, Breach decided that she no longer wanted the E.V.O.s and teleported them out of her dollhouse. Later on, a large group of Sklugg surrounded Valley Market and were fought off by Rex. They also appeared as soldiers working for Van Kleiss during his attack on the Keep and Providence Headquarters.
- They appear as enemies in the Generator Rex: Agent of Providence game.
- The orange variant is also explained to be a stronger variant called Sklugg Elite.
