Jay Endicott is a very ethical person who works as a bail bondsman. He is also the second (and best known) Crossfire, and in that capacity is a frequent ally of the DNAgents, having forged a particularly close bond with Rainbow, his love interest.
His initial connection to the Crossfire identity comes from having been hired by Lucius Krell to release the original Crossfire, Jeff Baker, from prison. As events unfolded, Jay found Baker's Crossfire flying suit and other equipment and decided to use them, initially to find out who had killed the first Crossfire.
As his alter ego Jay was able to follow his secret agenda to work for justice in a world turning more corrupt everyday. Rainbow and the other DNAgents often helped Crossfire with Rainbow helping him in several assignments. His cast includes a collection of colorful oddballs whom Jay aids and bails at times when necessary. These characters stick faithfully by Jay and are occasionally helpful during his missions.
