Demonicon

The Demonicons are (presumably) a Decepticon subgroup from the IDW portion of the Generation 1 continuity family.

The Demonicons are likely a group of Decepticons that get possessed by evil spirits.

Fiction

IDW Generation 1 continuity

At some point during the Great War, the Demonicons were exorcised by Optimus Prime. Drift would later refer to it as one of the few instances in which Optimus delivered the phrase "'til all are one". You, Me, and Other Revelations

Notes

• While not explicitly identified as such, the Demonicons were most likely Decepticons due to their use of the "-con" suffix.
