BB (BW)
BB is a Predacon from the Beast Wars II era of the Generation 1 continuity who was later upgraded into Max B.
BB is a hulking brute with limited mental capacity and very limited vocabulary. The only word in his dictionary is "Roger", as a matter of fact. He is perpetually loyal to Predacon Air Commander Starscream and goes along with all of his treachorous schemes.
BB can combine with Starscream in jet-mode to create the "Formation Scream" which enhances their aerial attack power. At one point, he was upgraded by Angolmois energy into Max B.
Fiction
Beast Wars II and Neo cartoon
Starscream was the brains of the Predacon air warriors and BB was the brawn (while Dirge and Thrust were the oafs). BB aided Starscream in numerous plots to overthrow Galvatron and take leadership of the Predacons, even going so far as to dunk Megastorm into a pit of Angolmois energy (this, however, only upgraded Megastorm into Gigastorm).
They continued this for quite some time until, eventually, Gigastorm had enough. While battling the Maximals, Starscream and BB fell into a trap Gigastorm had set for the Maximals (an area riddled with bombs). Gigastorm held off at first, but after the Predacons were defeated, Starscream began to beg for mercy and even offered to switch sides. This disgusted Gigastorm, who then activated the explosives. The explosion dropped Starscream and BB into a pit of Angolmois energy which upgraded them into Hellscream (a cybernetic shark) and Max B (a cybernetic wolf).
As Max B, he still continued to follow his partner Hellscream and fight against the Maximals up until the final battle on the battleship Nemesis. At the climax of that battle, Galvatron detonated the battleship, sending all the remaining Predacons (including Max B) floating helplessly through outer space.
Later, after the defeat of Unicron, all the exiled Predacons were invited back to Cybertron to help rebuild their desolated planet.
