Wu Cheng is a young Chinese pilot and member of the Blackhawk Squadron.

When the team adopted "secret identities" in the late '60s, Chop-Chop combined his martial arts skills with titanium gloves to become Dr. Hands.[1]

In the '70s, the nick-name Chop-Chop, which some considered offensive, was changed to Chopper. Chopper was the chief test pilot for the Cunningham Aircraft company.[2]


  • Although this character was originally introduced during DC's Earth-One era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
  • In Blackhawk #203, Chop-Chop is given an origin as a resistance fighter named White Dragon (real name Liu Huang). This tale was later retconned away when Mark Evanier's reboot gave him the name Wu Cheng.[3]
