Tiff of the Titans

"Tiff of the Titans" is the 34th episode of Darkwing Duck.

Synopsis
Fenton Crackshell, alias the crime-fighting Gizmoduck, heads to St. Canard in pursuit of Steelbeak. The F.O.W.L. agent soon finds out and frames Darkwing so Gizmoduck will think he's evil. The two fight it out, while Steelbeak tries to steal a new, top-secret weapon.

Trivia

 * Chronologically, this episode marks Gizmoduck's first appearance on Darkwing Duck. However, due to the anachronic airing order, it ended up airing as Gizmoduck's second appearance on the show (the first being "Just Us Justice Ducks").
