Upper Head: Depository of all avian warfare history and combat knowledge. This head is naturally the more agressive of the two.

Lower Head: Depository of all avian cultural history and knowledge. This head is the more genial of the two, and most likely to fall in love with green women.

For some unexplained reason, a knowledge-transfer with the Man-Beast caused the Bi-Beast to shrink to almost a third of its original hieght, but in later appearances, it seems to have grown some. This could be a power the Bi-Beast has yet to control, or it could be a byproduct of the machine used in the transfer.

The Bi-Beast is extremely durrable. Bullets have no affect on it, and it can easily take some of the Hulk's strongest punches without pausing a sentance. He has taken similar blows from Thor and Power Princess (Marvel's Wonder Woman), and fallen from as much as 8 miles in the air without suffering damage.

Although seldom used, the Bi-Beast can blast an unknown form of energy from the palms of his hands. One blast could rip an alligator to shreds or send Thor reeling.

(this is the brief version of Incredible Hulk Vol. 1 #169, 215, 216, Thor Vol. 1, 315, 314)
