Wallace invents the Mind-Meld-O-Matic, a device that's meant to make the rabbits he captures not want to eat vegetables anymore. After an accident where his brain melds with a rabbit's, he becomes a were-rabbit. After his failed experiment, Wallace turns into a giant were rabbit on the night of the full moon. Despite his huge size, the Were-Rabbit possesses enormous strength as he is able to lift up heavy trees, uproot vegetables, rip open greenhouses and leap off buildings. He is incredibly fast, being capable of outrunning even a road vehicle during a ground pursuit. It also enables him to easily burrow underground and escape threats. He also has an acute sense of smell and excellent hearing as he can easily detect food and sound from a distance.
