1987 animated series
Captain Hoffman is the leader of the Anti-Turtle Squad, a task force developed by the New York City government after the Punk Frogs robbed a bank, which they believed was instead perpetrated by the Turtles, because of their similarities.
In his first confrontation with the Turtles they were busy with the struggle against the Frogs. Hoffman found them with a tracking device that was tuned to the bio-rhythms of the Turtles. With an ice tank, he froze the Frogs, but Raphael was then able to disable the tank and the Turtles escaped with the Frogs. Later, a trick by the Frogs and Turtles led the Shredder to Stonewall Prison in search of Nyotrinaline which Shredder needed for the production of mutagen. Through his tracking device Hoffman could once again locate the Turtles and landed in a helicopter with some of his men on the roof of the prison. But by the special exploding arrows of the Punk Frog, Rasputin, the entrance to the whereabouts of the Turtles and the Punk Frogs was buried, so that they could escape again. Hoffman reflected that the Mayor wouldn't like this, and since he never appeared again, presumably suffered repercussions.
