Lira is an Eridani genetically-modified to appear Human. She was one of the two who inflitrated Alpha Flight's space station as crewmembers in order to sabotage their negotiations with the Eridani delegation, unwilling to let the slave class of Eridani be exploited even further to fulfill the additional needs of the vessel. She used the alias of "Ensign Jane Garcia."
Lira programmed a spaceship to fly to the asteroid belt between Mars and Jupiter and explode the 16 Sars asteroid in order to endanger the A.F.S.S. with its debris. Using Lt. Wendy Kawasaki's authorization, Lira also altered sensor records, in order to match the ship's energy signature with the Eridani's to pin the crime on them, which convinced the station's commander, Captain Marvel, to arrest them.
As Ensign Garcia, Lira was appointed acting counsel of the Eridani delegation when they demanded to be heard. The discovery that the sensor records were altered allowed Lira to pin the crime on Lt. Kawasaki; however, Captain Marvel cleared her.
When second-in-command, Abigail Brand, was investigating the sabotage, Lira knocked her out from behind in her office, and then used her computer to transmit a virus to Earth, affecting S.H.I.E.L.D. and the Ultimates stationed at the Triskelion.
As Alpha Flight was dealing with the threat of a Satori assault, Lira planted a bomb in the shield generators of the Alpha Flight Space Station. The second infiltrator, going by the alias of Lt. Bradner, died when when he blew up another section of the A.F.S.S., though the presence of a secret communicator allowed Brand to realize he was not alone.
Together with Lt. Kawasaki, Brand explored the base to uncover the second saboteur, and found Ensign Garcia trying to delete files to cover her tracks. When she was arrested, her true nature was discovered.
