Bucky O'Hare and the Toad Wars! (TV series 1991-1992)

In an alternative dimension called the Aniverse where the denizens are humanoid animals, the free worlds are threatened by the toads who are under the control of the insane computer, Komplex. The sole defence is the forces of S.P.A.C.E., which unfortunately, consists of a single ship called The Righteous Indignation under the command of Captain Bucky O'Hare. During one engagement, the ship's Photon Accelerator seriously malfunctioned, resulting in the disappearance of the engineer and the opening of a dimensional portal to the room of a human boy called Willy Dewitt, who is an engineering genius as well. Now, that boy has a part time job as part of Bucky O'Hare's crew as the war against the toads continues. - IMDb
