He at first was reluctant to have Voltron reactivated, believing diplomacy could be used to make peace with Lotor, but over time he comes to accept Voltron as a necessary ally. He is also the only one who fully trusts Zarkon, which is also his greatest weakness, as he was unknowingly reprogrammed by Zarkon to distrust the Voltron Force more and more, going as far as to have them decommissioned five times, and even put them on trial against the Alliance one time. When Lotor held the Troika Moons hostage in exchange for the destruction of the Voltron Lions, it was Amalgamus who gave the order to destroy them. This, along with Zarkon's position within the Alliance, left Galaxy Garrison open for an easy assault by Lotor at them end of the first season. By this time, Amalgamus had learned of Zarkon's true allegiance, but was helpless to stop Zarkon from turning him into a video game, and then later a cowardly blabbermouth later in the series. Toward the end of the series, he was retaken by the Voltron Force and restored to his original Voltron-allied programming, and exposed Zarkon's true plans to the Alliance.
