Bi-Beast

The Bi-Beast is presented in Marvel Comics as a constructed intelligence: a two-headed android created by an avian subspecies of the Inhumans. Left behind in the ruined city of its makers after their extinction, the Bi-Beast continues to operate as a caretaker and executor of perceived duties, reactivating when living beings enter its domain or when retrieval of a stored unit brings it back into contact with contemporary technology and societies.

Sources consistently describe the Bi-Beast as a two-headed android. Beyond its two-headed mechanical form, the provided summaries give no consistent additional physical particulars such as precise size, coloration, or materials; descriptions emphasize its constructed (android) nature and dual heads as its defining morphology.

Narrative sources describe the Bi-Beast as a highly advanced android that rivals the Hulk in physical prowess and that possesses an extensive knowledge of Avian warfare, culture, and science. It acts to preserve or execute the will of its creators—capturing individuals associated with them, instructing humans to repair or operate city machinery, and judging other species (at one point attempting to commandeer a Helicarrier to attack cities due to belief that humanity caused its creators' extinction). It can activate a self-destruct mechanism (used in at least one account) and narrative events record that a second unit, ejected in a cylinder, awakens possessing the memories of the first. The Bi-Beast has been captured and studied by the Stranger and later appears (or duplicates appear) participating in villain teams.
