Teenage Mutant Ninja Turtles #19 (1999)

Donatello is being questioned by the government authorities that believe the Turtle is an alien (due to his armor and the modified Triceraton aircar). The Feds try to call the Savage Dragon in to identify Don, but the fin-headed cop has gone missing - so some other super heroes from Chicago have come to check out the Turtle via a two-way mirror, but none of them recognize Donny. The man questioning Donatello tells him that he cannot leave until they find someone who can speak on his behalf. When informed of this news, Donatello gets upset and yells at the government agent. Don's actions alarm the heroes who have come to indentify him and they break through the mirror prepared for battle - fortunately, Horridus arrives and she recognizes the ninja before any more violence breaks out.
