007 Dr. Digit

Dr. Digit is a P.I. (private investigator) who became a G.I. (US military soldier).

His G1 figure was specifically called Dr. Digit P.I.  This figure has a huge afro with a pick in it.  He is a spoof of a spoof of a private investigator, specifically the main character from the 2002 movie Undercover Brother (starring Eddie Griffin). This movie is a satire of blacksploitation films of the 1970s. 

His G2/G3 figure still has the afro, the pick, and the sunglasses.  He now also has a fancy 1970s styled suit and platform shoes.

Later in G3, he got a second sculpt.  He went from a P.I. to a G.I.  He now wears military attire and a combat helmet (with an afro pick stuck in it).  G.I. means "government issue."  G.I. was initially stamped on military equipment but came to be a nickname for any soldier in the US military.

Dr Digit (G.I.) was also issued in G4 as part of the Trick Dudes series. He does a trick called the "360 Shov-It."  Crash and Jack also do this trick.

There are five additional Trick Dudes.  Duke, Turbo, and Matt do the "Kick Flip," while Robo Supreme and Metal Man do the "Front Flip."
