3. Leap-Frog

Leap-Frog is a thoroughly absurd supervillain who uses a frog costume to primarily antagonise Daredevil, for the suit contains electrical coils on two flippers which allow whoever is wearing it to fly up to 60 feet into the air. The original Leap-Frog, Vincent Patilio, was a toy inventor who had become frustrated by his lack of success, and decided to become Leap-Frog, though his criminal activities most often resulted in failure, being vanquished by Daredevil and even sent to jail by Iron Man. Though a later comic arc saw him turn to the good side and help Spider-Man out, he's a bonkers villain who also happens to be pretty useless. Sure, he can jump really high, but the guy just seemed to become a villain on a whim, and his heart wasn't in it. Plus, a frog suit - really?
