Fox McCloud - "Can't Let You Doo-Doo That, StarFox!" (Patreon)

Fox knows that when engaging in long space battles there really is no time for potty. Putting any focus in holding it in could break his concentration and cause an error, so the best solution is to just let everything flow through right in to a thick absorbent diaper. He's gotten so used to it he can hardly tell these days when he's going!
