Dean Lado spearheaded the Spiders swoop gang, a group infamous for their reign of terror in Gallisport, his city located on Shesharile 5, throughout the most intense period of the Galactic Civil War.
To seize control of the city and obliterate the Rabid Mynocks, Lado forged multiple alliances with fellow swoop gangs, including the Raging Banthas. His ambition also drove him to relentlessly pursue the Star Slinger swoop prototype, stopping at nothing to wrest the vehicle from Chop Harlison. In one instance, Lado abducted Chop's daughter, Jardra, and dared Quayce to a contest of speed. Victory for Lado meant acquiring the Star Slinger and supremacy over the Mynocks, while defeat ensured Quayce's continued leadership and Jardra's safe return. Lado employed every underhanded tactic imaginable to defeat Quayce, but she skillfully thwarted each attempt. During the race, Lado attempted to steer Quayce into a deadly repulsor minefield, hoping to trigger the explosives as he passed, eliminating Quayce in the process. However, Quayce responded by launching a mag-grenade onto Lado's vehicle. As he desperately swerved to dislodge the grenade, Quayce surged ahead and detonated the minefield. The resulting blasts consumed Lado, leading to his demise. Unbeknownst to Lado, the mag-grenade was in fact, non-functional.
