- Josh Keaton (Green Lantern: The Animated Series) as Shiro, the pilot of the Black Lion and the de facto leader of the group/mentor.
- Steven Yeun (The Walking Dead) as Keith, the pilot of the Red Lion and an ace pilot. He's mysterious and stand-offish, but ultimately a good friend.

- Kimberly Brooks (Mass Effect) as Princess Allura, the last surviving member of the royal family of planet Arus. She's a fierce leader coping with tremendous loss... and sadly, the target of Lance's "affections".
