As it’s St. Patrick’s Day, I have this Celtic themed fanon fight.
Clover (Payday 2)
Holly Short (Artemis Fowl).
(I’m guessing Holly will win because of her superior technology and magic, but the Payday Gang have done so much crazy stuff that you can’t count Clover out.) They’re thematic contrasts as well, with Clover as a notorious criminal and Holly a policewoman.
