The Bi-Beast is a huge android with tremendous physical strength. He has two heads, placed atop of each other, each with a distinct voice and personality.

Bi-Beast is first seen when the Avengers learn that Loki and the Celebrity Five are working on a way to bring the demon Dormammu to Earth from the Dark Dimension with the help of a device called the Dark Gate. They track down the Dark Gate to an abandoned warehouse, but Tim Gilliam and Joel Murphy are waiting for them there and unleash Bi-Beast and Iron Monger to keep the Avengers from entering.

Captain America, Wasp and Hulk fight off the two villains so Akira and Hikaru Akatsuki can enter the warehouse safely. Hulk takes on Bi-Beast, who easily matches him in strength. When Wasp attempts to help Hulk, she is captured by Bi-Beast, but released when Hulk resumes the fight. Eventually, Hulk is able to outmaneuver Bi-Beast and throws him into the air, causing him to crash land onto the floor.[1] He quickly recovers from this however and resumes the fight. For a moment it appears the two villains will defeat the Avengers, especially when the heroes time limit begins to run out. However, the Avengers' partners use their evolved Biocodes to give their heroes some more time, and also D-smash their second heroes Iron Fist, Power Man and Black Panther as back-up. The 6 heroes are too much for Iron Monger and Bi-Beast to handle. Both villains are subsequently defeated and D-secured off screen.[2]


Presumably those of Earth-616 Bi-Beast
