remaining two pieces, only for the Autobots to seize possession of the sword. A mysterious mercenary named Scavenger arrives on Earth and sides with the Decepticons, urging them to locate the components of the Skyboom Shield, another Mini-Con weapon that can counter the power of the Star Saber. At the same time, an Autobot drifter named Sideways enters the fray, but soon reveals his true allegiance to the Decepticons after he betrays Hot Shot, allowing the Star Saber to fall into the Decepticons' hands. Concurrently Scavenger reveals himself to be an undercover Autobot, and rejoins his fellows, soon followed by Blurr, the latest arrival from Cybertron. When the Decepticons complete the Skyboom Shield, a mighty battle ensues that ends with the Autobots gaining possession of the shield. The two weapons unleash a powerful energy flare, drawing the Decepticons, Thrust, a master tactician, and Tidal Wave, a large and powerful warrior, to Earth. Meanwhile, Sideways surreptitiously stirs up trouble in the Decepticon camp by playing on their contradictions. While luring the Autobots' human allies into cyberspace in an attempt to capture their Mini-Cons, Sideways reveals that he serves a mysterious higher power. Thrust arrives and puts his tactical prowess into play, only for his schemes to be foiled by the arrival of the Autobot, Jetfire, whose power to combine with Optimus defeats Thrust's schemes. Eventually, Sideways' deception is discovered and Megatron proceeds to destroy him with the Star Saber, only for Sideways to escape by reforming his body. Tidal Wave arrives on Earth, and the Autobots prove vastly outmatched. Rad, Carlos, and Alexis are alerted to the existence of the Requiem Blaster, the third Mini-Con weapon by Sideways, and locate Skyblast, one of its components. Skyblast sings an eerie harmony that summons the other two Mini-Cons from their stasis, and they form the Blaster, allowing Optimus to defeat Tidal Wave. Both sides soon gain new members in Sideswipe, an eager new Autobot, and Wheeljack, a former Autobot who has joined the Decepticons, believing that Hot Shot betrayed him on Cybertron. Thrust formulates a new scheme that allows the Decepticons to steal the Requiem Blaster, which involves mortally wounding Smokescreen in the process, causing Red Alert to re-format him into the more powerful form of Hoist. Starscream is his patsy, leading the already-alienated Decepticon to turn on Megatron and side with the Autobots. Starscream forms a friendship with the kids, particularly Alexis,
