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:
- Badass Boast: "I am the most fiendish terror that flaps in the darkest night! I am the skunk that pollutes your air! I am NEGADUCK!"
- Bad Guy Bar: Where Bad Darkwing finds Megavolt.
- Beyond the Impossible: While at a screening of The Cute Little Lost Bunnies Movie, Bad Darkwing somehow manages to get the attention of the characters in the movie by yelling at the screen. He then jumps into the film, scares the bunnies out into the real world, then emerges from the film in a tank.
- Big Ball of Violence: A mob gangs up on Posiduck. Gosalyn and Launchpad attempt to join the cloud, but are thrown out.
- 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 douses 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.
- Evil Sounds Deep: After galvinization, Negaduck's voice is much deeper sounding and given a filter effect to make him sound more warped.
- Evil Versus Oblivion: Megavolt's reason for joining Posiduck:Megavolt: If [galvanized Negaduck] destroys Saint Canard, there will be nothing left to steal!
- For the Evulz/Eviler than Thou:Negaduck (post-galvanization): Crime!? Who cares about crime?! I'm into wanton, mindless destruction!
- Freeze-Frame Bonus: Chip 'n Dale are seen on the TV before Gosalyn turns it off.
- Friend to All Living Things: Post-galvanization Posiduck is able to fix everything he gets near, inverting Negaduck's Walking Wasteland.
- Good Is Impotent: In a downplayed example, Posiduck is too much of a pacifist to be any use in a fight, even though he remains competent in other aspects (such as saving people from death traps). At the end of the episode, galvanization does give him superpowers that allow him to oppose the galvanized Negaduck, thus averting the trope.
- I Have No Son!: Played for laughs. Since the split was the result of his device, Megavolt initially regards Bad Darkwing as his son. After the newly christened Negaduck casts him off and vows to wreak massive upon the city, Megavolt shouts, "Ingrate! You're no son of mine!"
- 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.
- Oh, Crap!: The Cute Little Lost Bunnies' reaction to Bad Darkwing pulling out a gun.
- Megavolt's reaction to accidentally galvanizing Bad Darkwing/Negaduck is to silently cower in terror.
- Person of Mass Construction / Person of Mass Destruction: Post-galvanization Posiduck and Negaduck, respectively.
- 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.
- Too Dumb to Live: Megavolt tries to escape Darkwing by jumping out the window, only to immediately scramble back in. He somehow forgot they were on the 90th floor.
