While Prime is having to deal with the Dinobots leaving the Autobots, taking with them a human crafted mechanoid named Centurion, Emirate Xaaron has to deal with a miffed Impactor. He wants to be sure Ultra Magnus is ready in time for Operation: Volcano, which Xaaron assures him the Magnus will be. Optimus, Ratchet, and Prowl mysteriously disappear before the shocked optics of their fellow Bots, and elsewhere three Cons appear.. from the future, they are Galvatron, Cyclonus, and Scourge. Cyclonus and Scourge make nuisances of themselves attacking human settlements as the Bots spy on the present day Cons to see if they were involved in the disappearance of their friends. The future Cons meet with the present day Cons, Galvatron wants to borrow the Constructicons and are forced to "convince" Megatron into letting them have them. Meanwhile, Ultra Magnus is ready to go to Earth. The Constructicons build Galvatron a large gun that will kill Unicron when he happens upon Cybertron in 2005. Ultra Magnus arrives to present day Earth and helps out the present day Bots that were spying on the Cons. Magnus returns the injured Bots to base and learns of what happened with the Cons and with their missing comrades. Galvatron gives them a buzz to show off his new toy, the VVH, that he's using on Jazz. The Bots go to rescue their friend and are soundly defeated. Ironhide realizes that their only chance to find Megatron and Soundwave. On Cybertron, the Wreckers are practicing for the upcoming Operation: Volcano. Meanwhile, at the Ark Starscream awakens and he can't believe what he's seeing! Megatron at the Ark, commanding the Bots as to how to attack Galvatron. Ultra Magnus tries to find out what happened to Prime and the others. The Bots go after Scourge as Galvatron reveals to Jazz that he is a future version of Megatron. Impactor is attacked by Triple Changers, which later turn out to be Autobots who are testing the Wrecker leaders abilities. Galvatron explains to Jazz about the weapon that the Constructicons built. Future Bots come to our time, Hot Rod, Kup, Blurr and a hitchhiking Wreck-Gar.. Shockwave, Skywarp and Frenzy disappear just and Prime and the others did. Starscream joins forces with Galvatron as the future Bots meet up with Magnus. An exchange of prisoners (Jazz for Scourge) occurs but does not turn out well when Jazz goes berserk (thanks to Galvatron remote control). Magnus is briefed by the future Bots and goes to find them future Cons. Galvatron and Magnus have it out, Galvatron wins. He drags Magnus back to the site of his weapon and discovers his lieutenants unconscious (thanks to the future Bots) and said Bots detonate bombs. Starscream (actually a repainted twin of his) claims he has done this and Galvatron destroys him. Then he realizes that this cannot be the universe he wanted, but a parallel one and uses his time jump device to go back to the future. The future Bots put the real Starscream in cold storage and return to the future as well. Ultra Magnus realizes that he has spent too much time on Earth for Operation: Volcano has begun without him and returns to the Cybertron of his time. The Wreckers go on without him, awaiting for the Cons to strike at a trap set up by the Bots and using Xaaron as the bait. Impactor takes a death dealing blow for Xaaron during the Con attack and dies. Springer is named the new Wreckers leader. On Earth, the Bots and Cons that had disappeared have returned.
