He says he's a super genius, but in reality, he always end up flat due to his methods of capturing his prey.
Numerous times he has tried to capture the Roadrunner and Bugs Bunny, but to no avail. He also insists on using technology and ACME products, no matter how many times they backfire on him. Despite these shortcomings, he never gives up and will continue chasing his prey to the end of time. He also has a charming upper-class British accent as well.
