Actually here's what the Wikipedia article says:

"The Bi-Beast becomes aware of Banner's deception and fights Banner's alter-ego the Hulk, but is distracted when an AIM 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.[2]

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.[3]"
