Desmond Iridian the 3RD was a wealthy young engineer. He founded Iridian Technology Industries and continued running it until he was 94 and was struck with a fatal sickness. The disease crippled him for months, and he later died. Desmond Iridian's son who now goes by Hat-Top was frightful of the emotional exploitation of his dad's passing and removed himself from any ties of his father.

It was later revealed that Desmond had a history of hunting Sam which caused Hat-Top to pick up his viewpoints.
