The Bi-Beast is a fictional character appearing in American comic books published by Marvel Comics.

The Bi-Beast first appeared in The Incredible Hulk #169 (Nov. 1973) and was created by Herb Trimpe and Steve Englehart, who described it as "just another idea for something powerful/impressive enough to fight the Hulk."

The Bi-Beast is an 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, that species died out, and the Bi-Beast is left to its own devices in their city. 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 to the 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 MODOK storms the city. Rather than allow its home to be captured, the Bi-Beast activates a self-destruct mechanism and perishes in the explosion.

Unknown to all, a cylinder containing a second Bi-Beast is ejected from the city at the moment of the explosion. It comes to rest on the ocean floor, and is later retrieved and taken to the S.H.I.E.L.D. helicarrier. The second Bi-Beast awakens soon after, and imbued with the memories of the first, decides to take control of the helicarrier and launch its missiles at major metropolitan cities, believing the human race to be responsible for the extinction of its creators. General Thunderbolt Ross becomes aware of the danger and forcibly inserts Bruce Banner into the helicarrier, where he changes into the Hulk and battles the Bi-Beast once more. The two fall mid-battle through an opening activated by S.H.I.E.L.D., and plunge many miles to the ocean. The Bi-Beast disappears and is assumed to have drowned.
