Lasse Aeon

Lasse Aion is the Ptolemaois's gunner and the GN Arms' pilot.

When the GN-Xs began to attack the Trinitys, Sumeragi Lee Noriega had Lasse and Ian Vashti go to bring in one of the GN Arms. Lasse arrived just in time to save the Gundam from being destroyed by a GN-X squad. After attached the GN Arms to a combat container, Lasse and Setsuna F. Seiei departed for Earth to assist the Trinitys. Fighting against Ali Al Saachez, Lasse observed that his fighting patterns are strange.

Lasse was presumably killed when his cockpit was engulfed in explosions and smoke during the fight against Alejandro Corner. Afterwards, Setsuna tried to reach him.
