Boltmon

Boltmon is an Android Digimon whose name and design are derived from the fictional Frankenstein's monster, with "Bolt" as a reference to that name. It is a prototype Digimon constructed at the same time as Andromon. Unlike the mechanically-based Andromon, the organically-based Boltmon possessed emotions, as well as power that surpassed Andromon's, but because it was difficult to control and ran wild, it was consigned to oblivion in the darkness. Due to their egos, the scientists who created this unfortunate Digimon denied its own existence, so it began wandering within the darkness of its sorrow.

Digimon Adventure 02: The Road to Armor Evolution
A Boltmon appears in Ueno Park in the Real World during Valentine's Day and is encountered by Pukumon in the guise of a human. He talks Boltmon into causing chaos and captures Hikari "Kari" Kamiya, Mimi Tachikawa and Sora Takenouchi. The problem is that he just wants a heart. After Pucchiemon settles the problem with him and Davis Motomiya's identity crisis, Pukumon appears and uses the Control Spire to prevent normal Digivolution. After Pukumon is chased away, Boltmon takes his leave. Overall, Boltmon's issues are based on the Tin Woodman from the The Wizard of Oz.

A Boltmon was among the Mega Level Digimon that appeared to help the Digimon Sovereigns fight the D-Reaper. It is possible it may have digivolved from Clockmon or the Chuchidarumon (who may have merged into one when they digivolved, as the Infermon did).

Some Boltmon were seen working for Daemon. A Boltmon was with Neo Saiba during the invasion upon Lord HolyAngemon's castle where he killed two Knightmon with an axe longer than usual. He then fought against Leo, but he underestimated the Ultimate Digimon and was cut in half by Leo's sword. Another one was killed by Callismon, one of Neo's experiments.
