'''Lt. Colleen O'Reilly''' was ''Avery F. Butler''<nowiki>'</nowiki>s right hand man...err...woman, and the communications and tech specialist of the Charlie-Five Squadron. One of the best officers of the entire Exofleet, O'Reilly had a personal [[vendetta]] against ''Phaeton'' and his regime, since the day when nearly all her friends from the ''Exofleet Academy'' were killed in the first Neosapiens assault on Earth (it also was the day of her and their [[graduation]]). Over the time, she developed a tender relationship with ''J.T. Marsh'' but following ''Butler''<nowiki>'</nowiki>s incapacitation she was forced to assume the command over the squadron and to put all relationships aside for a while. During the war, O'Reilly used an ''#LS-042 E-frame''.
