Seen in King of Braves GaoGaiGar FINAL, LinerGao II is the replacement for LinerGao. Utterly unlike its predecessor in almost every way, this rendition of LinerGao takes the form of a blue-green rocket ship. During Final Fusion, it detaches six side boosters and unfolds like a clamshell to interface. Forms the shoulders and upper arms of both GaoFighGar and GaoGaiGo.

Either half of LinerGao II can be detached from GaoFighGar and used as a means of escape in the event of an emergency, as seen in Episode 6 of FINAL.
