Duocon

Duocons are a subspecies of multi-component Cybertronians from the planet Cybertron.

Biology
While also being a subgroup of Decepticons, Duocons consider themselves a species unto themselves.

Anatomy
Duocons share a similar biology to other Cybertronians, except they transform from individual robots into two separate vehicles and vice versa. According to Vector Prime, they also possess mitotic sparks.

Powers and abilities
Duocons share many of the same abilities as other Cybertronians, namely multi-component Transformers.

History
The Duocons were created by Decepticon scientist Shockwave when he experimented to create a Transformer with more than one alternate mode. While he eventually succeeded with the Triple Changers, an early step in the process resulted in the Duocons. They were considered a failure due to their consciousness being split between two vehicles.
