Gai is the leader of the Serpent Tail mercinaries. Hes a coordinator and doesnt side with either Earth Alliance or ZAFT. He only does jobs to scout bomb or steal mobile suit technology. After meeting Lowe Gai befriends him after stealing Lowes Blue Frame Astray. Like Lowe he believes that mobile suits have a hidden strength only the pilot can feel. But he could care less if the war ended or not as long as hes being paid to do the right thing.
