This Must Come as a Shock Following the Viltrumites' attack, Mark spends two months helping Thraxa rebuild before returning to Earth with his brother. At the GDA, Donald confronts Cecil about his body. Cecil reveals he successfully recovered Donald's brain and placed it in a robotic endoskeleton. The Guardians discover a Martian ship bound for Earth, prompting Shapesmith to reveal his identity and the impending Sequid invasion. After Eve recommits to heroism with Rex's encouragement, Cecil recruits her and Mark to join most of the Guardians in thwarting the invasion, but they are overwhelmed. Concurrently, remaining Guardians members Rex, Dupli-Kate, and Shrinking Rae confront the Lizard League after they capture a military base to ransom its nuclear missiles. Though Rex kills most of them, Komodo Dragon kills Kate and devours Rae and one of Rex's hands before dying. King Lizard subsequently holds the injured Rex at gunpoint. Meanwhile, Allen recovers from his injuries despite Thaedus' actions and has become as strong as a Viltrumite. Thaedus reveals he is a rebel Viltrumite and tasks Allen with recruiting Mark to aid the Coalition against the Viltrum Empire.
