Exosquad - Season 2 - Eps 12: The Greatest Fear
Able Squad arrives on Venus with the mission of locating and estimating every Neo base and troop concentration on the planet, as a prelude to invasion. While investigating a secret research facility Torres and Bronski are discovered, and in the battle to retrieve them Marsala is captured. He is taken inside, and sees that the facility is for research related to AutoMutation Syndrome (apparently a Neo sapien version of cancer). To prevent Marsala from divulging ExoFleet plans for an invasion Marsh sets out to destroy the facility with Marsala inside. Nara is unwilling to let Marsala be killed, and she goes to rescue him. She manages to succeed before Marsh finishes demolishing the complex, and on their way out she and Marsala unwittingly capture an experimental subject that merged with the Neo mega Lysander.

Synopsis
Sometime in the 22nd century, humans have fully terraformed and colonized Venus and Mars. The Neosapiens, an artificially engineered race created to be slaves for the Terrans, have turned against their masters and formed the Neosapien Order/Empire/Commonwealth. Under the rule of the calculating Governor General Phaeton, the Neosapiens have launched an invasion of Earth and Venus. The ExoFleet, the Homeworlds' space navy (in particular, Able Squad, a group of Exo-Frame pilots led by Lieutenant J.T. Marsh), fight against the invasion in an interplanetary war to protect the Terrans.
