Anime Bass was born of the remnants of PharaohMan's data, which were extracted from the Navi by Wily, who wanted his Ultimate Program. Bass had no memories of his previous life as PharaohMan until he abducted MegaMan and read his memories, learning his origins and awakening his "true self". Bass attempted to consume the data of Gospel (Grave in the English anime), for the two shared the same origin, to become whole, only to be consumed himself. When MegaMan destroyed Gospel and restored all the NetNavis devoured by the beast, Bass took residence in Shuryou Gospel's (Kid Grave in the English anime) android body. He left, vowing revenge against the world.

He reappeared as the creator of the robot Allegro in Axess, and tried to absorb MegaMan and ProtoMan's Ultimate Programs at the beginning of Stream. He was easily defeated by Slur and imprisoned in the UnderNet, losing his means of travel through the human world in the process. In RockMan.EXE: Program of Light and Dark, a film exclusive to Japan, Bass is captured by Dr. Regal and is brainwashed to obtain the Tadashi Hikari Program, and fights MegaMan and Colonel. Bass, upon returning to normal, wanted to make Regal pay for the "disgusting act" of a human using him as a pawn, even if meant siding with MegaMan. The duo were no match for Nebula Grey, so MegaMan opted to have Bass absorb his Ultimate Program.

The resulting BassCross eliminated Nebula Grey, but Regal summoned a black hole in a last ditch effort to destroy the Navis along with himself. Bass flung MegaMan out of harm's way as he himself got sucked in, ultimately absorbing Nebula Grey's power, which proved vital in his rematch with Slur. The tables had turned, and he deleted her, impaling her through the chest on his arm and suffocating her. He vanished, and his current whereabouts are unknown.
