When an encounter with Megavolt's tron splitter splits Darkwing's good and evil sides, Gosalyn and Launchpad must race to put them back together before Darkwing's evil half tears St. Canard apart.
This episode contains examples of the following tropes:
- Big Ol' Eyebrows: Negaduck spots these, as a way the viewer could tell him from Posiduck was his thick black angry eyebrows.
- Black Eyes of Crazy: Negaduck's sclera turn black.
- Casting a Shadow: Negaduck, kinda. His negative energy manifests itself as evil-looking lightning and energy balls.
- Combat Pragmatist: While facing off against Megavolt in the Old Haunt, rather than fight him, Negaduck dosses him with a pitcher of water.
- Enemy Mine: Megavolt helps to bring Darkwing back to normal and stop Negaduck from destroying everything. The truce ends when Darkwing is put back together, after which Megavolt tries out his tron splitter's zoom lens on him.
- For the Evulz/Eviler Than Thou:Negaduck (post-galvanization): Crime!? Who cares about crime?! I'm into wanton, mindless destruction!
- Friend to All Living Things: Post-galvanization Posiduck is able to fix everything he gets near, inverting Negaduck's Walking Wasteland.
- Light Is Not Good: Post-galvanization Negaduck's costume is a lot lighter than Darkwing's dark costume and produced light blue energy.
- Literal Split Personality: Darkwing is split into good and evil sides, which are later enhanced into super-good and super-evil sides.
- Pragmatic Villainy: When Megavolt willingly helps the others stop Negaduck, Gosalyn asks him why. Megavolt explains that if Negaduck destroys St. Canard, there would be nothing left for him to rob.
- Super Mode: What happens when Darkwing's bad and good sides are exposed to galvanization, significantly boosted their abilities to the point of making them Reality Warpers.
