Ali Liu participated in Operation Menelaus as head navigator aboard Griffin. He was often trusted by Elliott Parks with standing in for him on the bridge when matters requiring the captain's attention took him away.

After returning from the ill-fated Operation Menelaus, Liu transferred from Griffin to another vessel for six months while the carrier underwent extensive repairs.

Liu returned to Griffin was navigator as soon as it was cleared for duty and acting as helmsman when the carrier was taken to Mythos. He was later placed in charge of the ship when Elliott Parks made his way to New Malaga, in search of the White Knights and the ATAFs.
