Swoop

Like Grimlock, Swoop was a member of the brutal Lightning Strike Coalition- that is, until he was taken captive by Shockwave and forcibly changed into a Dinobot. And, like Grimlock, he is a powerful warrior, and though the other Autobots undoubtedly think of him as dim, he's at least enthusiastic about fighting Decepticons. But unlike Grimlock, Swoop enjoys his new form, revelling in the power and speed of his new pterosaur alternate mode.

Fall of Cybertron comic
Sent by Grimlock to investigate the Decepticons' seemingly neverending supply of energon, Swoop found and infiltrated an enemy base where he overheard Shockwave discussing with Starscream that he was not only responsible for the energon situation, but had also uncovered an army of Insecticon warriors for the Decepticons to use. He was discovered before long and set upon by the Insecticon swarm, which proved too much for him. Secrets Before he went down, Swoop sent an emergency message to Grimlock telling him about his discovery. He was strung up to a harness to serve as bait for the rest of the Lightning Strike Coalition, who were themselves attacked by Insecticons when they came to save him.

Rage of the Dinobots comic
Swoop and the Dinobots aided in helping Impactor's convoy of ships to escape Cybertron's atmosphere. Swoop covered Snarl's back by dealing with the Decepticon ground troops led by Blast Off. When Ultra Magnus ordered the Dinobots to get to their own craft, another squadron of Decepticons drew Swoop into a solo attempt to take them out. Magnus ordered Swoop away and fought the Decepticons off, but his ship was shot down. While some of the other Dinobots were considering leaving Magnus behind, Grimlock refused to do so and commenced a rescue mission. Ser-Ket, however, listened to their conversation.

A Predacon beat the Dinobots to Magnus' ship, and Swoop was taken out. After Grimlock transformed into dinosaur mode to save his comrade, he lost control of himself and turned on his own men. The Predacon flew off with an unconscious Swoop.

Swoop had awakened in prison-base of The Forged. His first sight was of Ser-Ket, who called him "Brother." Upon realizing where he was, Swoop accused her of being a Decepticon. Ser-Ket scoffed at this, saying factions were meaningless now that Megatron and Optimus Prime were gone. Swoop asked of the fate of Ultra Magnus. Ser-Ket said not to worry, he'd be reunited after the Master arrived. Staging a rescue, the Dinobots failed to find Swoop among the prisoners. Reasoning that he too was moving to the roof to escape, they did likewise. Encountering Ser-Ket, Grimlock demanded that she hand over Swoop, but she revealed that he had been re-forged. Hailing his new master Shockwave, Swoop attacked!
