Having recently escaped from his entombment in Mount Verona, Galvatron approaches the Decepticons' island base, causing Shockwave to fear for his position as leader. Against Soundwave’s recommendation he unleashes the Seacons who have recently arrived on Earth to fortify the base. They attack Galvatron much to the future Decepticon’s amusement. Galvatron then leaves Shockwave to deal with his angry troops. His plan had always been to undermine Shockwave’s leadership so that the Decepticons would ultimately welcome him when he later takes control.
