Unlike the other villains, he considers Ron Stoppable a worthy opponent rather than a clownish sidekick. He considers Ron (and Rufus) as the only others, besides himself, exposed to Mystical Monkey Power. Although Ron considers Monkey Fist his arch-foe, in "Gorilla Fist" Fiske refutes him as at best an arch-bungler. Ron once comments that he is the only one of their regular foes who regularly remembers his name, which he appreciates. He also is the most confrontational of the villains, showing a willingness to battle them directly as opposed to the death traps Drakken and others employ.
