Update: I have 3 new OCs, all male
Here are some mini-bios on the guys:

Xenji-Vortian, Naomi's kind, tender-hearted lover (eventaully-he crushes on her, then makes a move ). Superior technological skills. Once a servant on the Massive, he was imprisoned for continually sneaking into the technology departments to build things that would assist in any future escape attempts

Rey-Irken, Leina's smeethood best friend. Brave, dutiful, loyal. Prison guard in training, hence the symbol on his forehead. Secretly against the Irken Armada, just like Leina, but he finds nothing wrong with that. Leads Leina, Naomi and Xenji's prison break. Dunno if he and Lin (Leina) will end up together...

Jett-Irken, man of very few words. Very stealthy, very agile when fighting. Has a scar on his left eye, seems to always be in a bad mood.

Might as well have mini-bios and notes on the other characters too:

Titan- SIR unit, older brother figure to Sterling. Intelligent and a peace maker.

Sterling-SIR unit, sees Titan as an older brother of sorts. Has childlike cuteness and personality, but he is open minded; very agile.

Leina, aka Lin-Irken, smeethood best friend is Rey. Prisoner interrogator in prison where Rey now works. Believes that all alien races should get along and stands proud in her beliefs, but fears that her thoughts make her a defective. Befriends Naomi during her interrogation; befriends Xenji when she is herself imprisoned for treason.

Naomi-Vortian, intergalactic peace advocate who tries to aid those in need of medicines, food, and otehr such needs. Befriends Leina in prison. Kind and gentle, an all around beautiful person. Excellent Planner and organizer.

The one on the bottom right is not really an OC-it's me
