Ace Duck is a pilot who was forced into an intergalactic wrestling match.
Ace Duck finally appears in the IDW comics series in his incarnation as a combat pilot, where he meets the Ninja Turtles in an adventure in Dimension X on the planet Palmadise. In this version, Ace was originally a member of a special unit that fought side by side with the Neutrinos against their Utrom invaders. After he and his crew were shot down, his comrades were executed mercilessly by Krang despite their surrender; Ace escaped to Palmadise a planet controlled by criminal cartels, where he continued to fight against oppression and tyranny, and thus provoking the displeasure of the criminal bosses. When the turtles appear on Palmadise to pick him up for Krang's trial, Ace only joins them after a few doubts of confidence.
Tristan Huw Jones indicated that a brief gag involving Ace as a Nazi-fighter on a TV show was to appear during Infestation 2, but this was cut from the final print version.
