Most of the ideas from the comic book were used for the cartoon, with several major differences: The parallel universe the story takes place in is named the "Aniverse", Willy DuWitt can travel freely between Earth and the Aniverse instead of being stranded there, Bruce is transported into another dimension instead of killed, the Toad Empire are willingly following KOMPLEX instead of brainwashed, Deadeye has a Southern accent instead of a Scottish accent, the nigh-omnipotent mouse is nowhere to be seen, and Jenny reveals her psionic powers to Willy DuWitt. The cartoon explored more of the aniverse and followed a loose unifying arc, with Bucky's home planet of Warren being captured by the toads in the season premiere and rescued in the finale.
Characters
Bucky and his crew are members of the S.P.A.C.E. organization, which stands for Sentient Protoplasm Against Colonial Encroachment.
Bucky O'Hare –- a green hare, captains a S.P.A.C.E. frigate named The Righteous Indignation. Voiced by Jason Michas. His crew consists of:
Jenny –– first mate and pilot, a cat from the planet Aldebaran with mysterious magical and psionic powers common to the females of her species. They include telepathy, astral projection, energy blasts, and healing. Because of the sacred precepts of Alderbaran, she keeps these powers secret from the other members of the crew, with the exception of Willy, for whom she has overt romantic affections. Voiced by Margot Pinvidic.
Bruce –– Bruiser's brother, a Betelgeusian Berserker Baboon who served as the Righteous Indignation's engineer. He vanished into another dimension when the ship's photon accelerator malfunctioned during battle. Voiced by Dale Wilson.
Willy DuWitt –– engineer, a pre-teen human from San Francisco who enters the Aniverse via a portal between the ship's photon accelerator and his own accelerator at home. He replaced Bruce, the former engineer, who was killed. Later, Willy became stranded in the Aniverse when his parents turned off the photon accelerator back in his room. Bucky and his crew decide to keep Willy a secret from the S.P.A.C.E organization and the Toads. Voiced by Shane Meier.
Dead-Eye Duck –– gunner, a four-armed former space pirate duck from Kanopis III. He is missing an eye, and is impatient and violent, preferring to let his four laser pistols do the talking for him. Unlike the comics where he has a Scottish accent, he has a Southern accent. Voiced by Scott McNeil.
AFC Blinky –– an advanced AFC. Has only one eye. Uses the phrase "Calamity and Woe!" to identify problem situations for Bucky and his crew-mates. Voiced by Sam Vincent.
The members of the Toad Empire introduced are as follows:
KOMPLEX –– the undisputed ruler of the Toad Empire. This computer program was designed to run the consumerist toad culture but instead took it over and militarized it. Its name, in toad language, is an anagram for 'Feed me'. Voiced by Long John Baldry.
Toad Air Marshall –– one of KOMPLEX's foremost commanders, with a uniform adorned with medals and a face covered in warts. Voiced by Jay Brazeau.
Toad Borg –– a large, purple cyborg second-in-command under KOMPLEX. Voiced by Richard Newman.
Storm Toads –– the mindless toad soldiers who serve as the primary attack force for the Empire.
