Achilles and Ulysses

Achilles and Ulysses were two reploids featured in certain Blood of the Chozo writings that survived into a series recap in Nintendo Power. Both reploids piloted a ship carrying a mile-high Chozo Statue, which they landed on Oztaki, to the delight of Dr. Vincent.

Etymology
In Greek mythology, Achilles was a demigod, with every aspect of him considered invincible except for his heel. Ulysses is derived from the Latin name for the Greek hero Odysseus, famous for the ten eventful years he took to return to his home of Nostoi after his successful capture of the city of Troy.
