Ethan Zachary

In the Marvel Generation 1 comic, Ethan Zachary was a human computer programmer who oversaw a game of Multi-World between Optimus Prime and the Protectobots and Megatron and the Combaticons over control of the hydrothermocline in Marvel US issue #24. He eventually saved Prime's entire memory and personality onto a floppy disk (no, really) in the wake of Prime's subsequent death. Zachary later resurfaced in Marvel US issue #40, in which he gave the disk to Goldbug, Slapdash, Joyride and Getaway so that they could have a new Powermaster body built for Prime.
