Frax is a high-ranking officer in the Toad Empire who serves as an assistant to the Toad Air Marshall. He is the nearly-identical companion of Frix. But all the confusion changes after Well-Done's mutagen turned him into the sword-wielding mutant named "Slice". After Dave defeats them the first time, Dave chose to let them go since Dave felt that he doesn't care about killing anyone. Later, Dave faces Slice after Air Stryker and Fighterbot. Slice later when he assists Rollbot, only to be defeated when Dave tosses him on a landmine. He and Dice fit the category of Decimator's army.
