Burke was once Jett's partner on the planet Cerberus. However, he hated being under Jett's shadow and betrayed her by framing her for killing the king of their planet.
After Jett became a wanted criminal, Burke helps her escape by commandeering a space shuttle. However, their shuttle is shot down, sent through a backlash wormhole, and crash lands on Maple World. Burke then steals Jett's Core and attacks her after she regains consciousness, revealing the reasons of betrayal. Jett reveals that Burke can't utilize the Core because it is a heredity item only for Jett's family; Burke doesn't care, for he wants to be at least equal or more powerful than Jett. His repeated attacks cause her to pass out, where she is discovered and recruited by the Pirates who agree to help her track Burke.
Burke later strikes a bargain with Baroq, trying to unlock the Core's powers using an item that the Black Wings have. However, Baroq eventually betrays Burke and attempts to use the Core to awaken the Black Mage. Burke sacrifices himself for Jett and reveals the true location of where he hid the Core so the Black Wings can't get it.
