Rocky era um dragão que vivia calmamente na região sul do planeta Gan-mah, até o dia que aconteceu uma rebelião contra o governador Krad, que havia investido todos os recursos de seu planeta em uma nave intergaláctica, construída para irem ao planeta Terra, acharem a lendária XGem.

Junto de Alfred, Rocky invade a nave, mas são descobertos quando já estão no espaço, perto da Terra. Após serem perseguidos por vários inimigos, eles se vêem encurralados e deixam a nave, caindo em um lago da Terra.

Depois eles encontram um depósito abandonado e se abrigam lá, quando escutam o grito de alguém. Rocky vê um garoto ameaçando uma garota em um beco e o assusta.

Rocky oferece ajuda a garota Renata que quer agradecer de algum jeito, quando Alfred pede um lugar para eles passarem a noite. E depois desse dia várias aventuras aconteceram com Rocky, Renata e Alfred na cidade de São Janery. Ele não gosta de chuvas por que lhe traz lembranças ruins.
