I like him, I love the way you draw him as well! Honestly, I don't understand why he's often depicted as a "loser criminal" when he was portrayed as legit threat when first introduced. His intelligence could be even matched with Batman, which is why the other criminals were willing to hire his services. I don't get why the writers decided he should be taken as a joke afterwards, his colorful costume isn't an excuse because we got villains like Joker and so on. I wish he was given a proper spotlight, but oh well.
Great job!
