Weegario was made when Wario got the Weegee virus. Wario escaped the Weegee virus, but he split into two. Wario was still Wario, but his Weegeefied version was manifested into a separate organism. People called him an imposter of Walleegee, so he decided to work for The Anti-Weegee Alliance to express his anger. He was offered to join the Wario Family but he declined the offer. Weegario killed Daialleo out of complete anger over Daialleo firing him from his restaurant.
