Kyubitmon is the Champion form of Renineamon, a Renamon whose data collided with an advanced combat A.I. program when it was generated, wiping the Digimon's innate knowledge of the Digital World in exchange for a learning program that enables it to perform attacks of other Digimon, even if the Digimon is a completely different class or level. However, such unmitigated power has caused Renineamon to become an outcast in her own land.

Kyubitmon is similar to Kyubimon, only with a bigger technological influence, with the neck ornament replaced with a computerized grappling system. Kyubitmon also has a visor over its eyes as part of its ability copying power, which is enhanced in this state, though the attacks gained in this form cannot be used by Renineamon. Kyubit also grows a bit overwhelmed by the program, and has trouble fighting off its combat programming which risks overriding her common sense.
