We know that the Light already has the Warworld, a bunch of meta humans, and an army of Kryptonians. But they wouldn’t just use them to conquer the galaxy, (or at least I don’t think that’s what they would do). Instead, Vandal would create a group of very influential aliens from across the galaxy, and convince them to start working for them, doing some favors in exchange. They’d do this by having formal reunions with them or straight up starfishing them with Starro Tech. Of course, they wouldn’t allow any of them to join the Light, since it’s a group that focuses primarily on humans, (especially after the whole Granny Goodness fiasco). Instead, they’d use them to gather information about different planets and start preparing them for conquer.

This group could be:

  • Mongul.

  • Despero.

  • Ma’alefa’ak, (White Martian).

  • General Zod, (Kryptonian).

  • Siniestro, (Yellow Lantern).

  • Atrocitus, (Red Lantern).

  • Blackfire, (Tamarean).

  • Imperiex.
