Super Looney Tunes - Bugs Brigade International.

 The Super Looney Tunes were released with McDonalds happy meals back in 1992, amalgamating the Warner Bros cartoon characters with DC superheroes. The set of four was made up by Bugs Bunny as Super Bugs, Daffy Duck as Bat Duck, Porky Pig in drag as Wonder Pig and The Tasmanian Devil as Taz-Flash. 

The gimmick of the toys was that you could switch them from the regular characters of Bugs, Daffy, Porky and Taz to their superhero identities with snap on outfits. 

The Looney Tunes comic at the time featured strips about the Super Looney Tunes naming them the Bugs Brigade International.
