Will Smith Fish is one of the main antagonists of Bee Shrek Test in the House. He's a talking fish with the facial appearance, behavior, and basics of Will Smith, but lacks the charm, charisma, and general coolness that the actor has. He was originally an ally of the Big Four, but now plots against them and has formed and joined various organizations to accomplish said goal.
Will Smith Fish is under the delusion that he's cool, hip and popular. He isn't. He's terrifying, hated, and his mother never hugged him. In the Seventh Season episode, The Geniuses and the Fish, it is revealed that he has a much deeper character. He was so miserable due to being hated and discriminated against because he wanted to bee cool that he commited suicide by angering Little King John, but as punishment, he was brought back to life against his will.
