Bull-eye, aka Leapo the clown, is often described as Green Arrow's answer to The Joker by far the best villain to have been introduced to the big screen from DC. It's time for Arrow to try a Leapo faith (I couldn't help myself). Before Merlyn, who we've already seen play a huge part in Arrow, Bulls-eye was Green Arrows arch-enemy. He's a great firearms man and is able to work past Arrow's weaponry. Obviously, this presents a huge challenge to Oliver as he has to resort to techniques he's not used to. We love to see our heroes overcome the hardest challenges and I'm not sure there's a bigger one than Bulls-eye. The show could easily introduce the character in the same fashion that they have done with numerous other comic book villains, including Brother Blood, The Clock King and Deadshot. A similar approach to introduce Leapo would be fantastic and he'd fit in with the show perfectly. Bulls-eye could easily become one of the big villains in season three and would present Oliver Queen with a huge test throughout the season. In the comics, Bulls-eye is also behind the training of many more Green Arrow villains, and this means that it could be turned into a fantastic long term story.
