Bi-Beast

The Bi-Beast was originally a huge android with two heads (one atop the other - the top skull is given knowledge of warfare while the bottom skull was given a knowledge of culture) created many years ago by an Avian race that were in turn a sub-species of the Inhumans. For reasons unknown, the Avian race dies out, and the Bi-Beast is left to its own devices in the Avian city.[1]Years later, the creature sees the Harpy with Bruce Banner, and is reminded of its former Avian masters. The Bi-Beast captures them both and instructs Banner to fix the now-decaying machines in the city. Banner instead chooses to cure the Harpy, who reverts back to her original form of Betty Ross soon after. The Bi-Beast becomes aware of Banner's deception and fights Banner's alter-ego the Hulk, but is distracted when an A.I.M. strike force led by M.O.D.O.K. storms the city. Rather than allow its home to be captured, the Bi-Beast activates a self-destruct mechanism and perishes in the explosion. [1][2][3]The Bi-Beast appears as a illusion created by the Shaper of Worlds.[4]

His image is used in one of the illusions created by Mentallo.[5]
