Cyclonus is a Decepticon.
While the Decepticons were training on the streets of Iacon, they received a message issuing a challenge from Cyclonus. Cyclonus met a small group of Decepticons atop a building, announcing he was going to "bring them back to reality". They proceeded to battle until Cyclonus was soundly defeated and agreed to join the Decepticon cause.
He was subsequently part of the mission in which the Decepticons kidnapped Swoop for their Dark Energon experiments. As the Autobots tried to retrieve their friend, Cyclonus confronted them. Standing behind a force field, he unleashed his "minions" — some swarms and a few turrets — to attack the Autobots. When those fell and his forcefield was disabled, Cyclonus was reduced to a cowardly wreck, promising to open the door to the laboratory if they didn't hurt him. Once the Autobots had retrieved Swoop, Cyclonus revealed he'd rigged the lab to blow and sped off in his jet mode, activating more force fields to keep the Autobots from following him.
