(note: this is an amalgamation of Lancer from Robotech and Yellow Belmont from Genesis Climber MOSPEADA)
Born in the tumultuous following the First Robotech War, Lancer grew up with a love of the theater, mainly the Japanese art of Musume, and music.
Even though he grew up to be a talented singer, Lancer served his time in the Military in either the REF (RPG) or the Armies of the Southern Cross (doesn't say in the animation).
After being shot down and wounded while fighting the Invid, a woman named Carla takes care of him until he recovers. During their time together, the people of Carla's hometown cooperate with the Invid to hunt down resistance fighters and ex-military soldiers. To protect Lancer, Carla disguises him as a woman.
The disguise works, and a new identity is born.
After falling in love with Carla, Lancer decides to leave her, so she will remain safe while he fights the Invid alone.
Using his musical talents and the disguise given to him by Carla, he adopted the identity of a female pop star, Yellow Dancer, to protect his own identity, and allow him to fight against the Invid.
This is how he meets Scott Bernard, Rand, Annie, Lunk, and Rook.
When Rook and Scott come to Yellow Dancer's aid in a bar room brawl, he helps them save Lunk's friend, and joins them in their fight with the Invid.
It is during this time that he is able to let go of his feeling of Carla, and he meets his next great love, Sera, The Invid Princess.
It is with his help, inspiration, quick mind and wit, and combat skills that Sera, Marlene/Ariel, and the rest are able to convince the Regis to leave the Earth.
