Starscream is a Transformer in the Beast Wars Universe. He is one of the Predacons stationed on the planet Gaea. His vehicle mode is a Fighter Jet. He is ALWAYS scheming to overthrow Galvatron as leader of the Predacons, just like his Decepticon namesake, Starscream. He can combine with his partner BB to form "Formation Scream". He was later upgraded into Hellscream whose beast mode is a transmetal 2 Great White Shark. Hellscream likes this new beast mode. He is also a narcissistic butthole, who cares too much about ruining his paint job.
In the marvel cinematic universe Starscream and BB there were battling Captain Marvel and Captain Marvel shot her energy blast which possibly kill them but when they absorbed the energy and he became the transmetal 2 great white shark becoming Hellscream and he like his new form.
