Persei Eight

Persei Eight is probably a planet of some kind. The Omacronians come from there.

Fiction

Wings of Honor

At some point, Magnum's Elite Guard team fought against some Omacronians. Kup was reminded of the event during a later battle of Cybertron. It's unclear whether the battle he was recalling actually took place on Persei Eight. Battle Lines, Part 3

Notes

• The Omacronians and their planet are likely a reference to the planet Omicron Persei 8 from Futurama.
