Almost Killed
Cortex, along with the other villainous scientists of the war, resolves to gather his forces and take over the world. However, his plans are interrupted when Dark Samus breaks into his fortress. In a panic, Cortex summons Crunch to deal with the threat. Cortex makes his escape, though not before witnessing Crunch's death at Dark Samus's hands.
War By Proxy
It is revealed that Cortex has near total control of the global political underworld, as he is the creator of Boss Cass and various other villains stirring up local trouble. Cass serves as a liaison to Cortex, who focuses on the larger goals of the war. Cortex originally has the minor agent, Swampy, build a munitions factory to supply his forces, but the crocodile is killed when Baron Dante attacks. Cortex later has Arpeggio build a Clockwerk armor prototype, but both birds, mechanical and organic, are destroyed. Cass reports the successive stories to Cortex, who is reasonably enraged by the failures. He orders Cass to have the Fiendish Five wipe out the Boss Brigade of Erol, one of Ganondorf's top men. Though the Five succeed in taking out most of the Boss Brigade, Erol manages to finish off them all.
