Deron is Cactus's son. He took up his father's forgery business after Cactus's death and is based in Washington, D.C.
- Deron is said by Bourne to be able to forge almost anything, but his specialty is Vermeer paintings.
- When not working on a new forgery, Deron enjoys playing with new technology. One of his ideas was a rubber-coated plastic semiautomatic handgun firing Kevlar-coated rubber bullets. Deron told Jason that it "could put down a bull elephant if hit in the right spot."
