The Negaverse Tank or Nega-Tank ran blindly across the streets of the Darkwing Duck City while frantically checking if anyone was chasing him.

"Drake Mallard's House is my only hope, where does Darkwing Duck live again?" The Negaverse Tank asked himself panickingly glancing at the Street Names trying to remember where he was going.

The Negaverse Gosalyn Brainwashed the Friendly Four into helping her take control of the Negaduck Empire for herself.

Negaduck Brainwashed Gosalyn into being the Nice Clean Freak that the Negaverse dismissed as harmless until she infiltrated the Friendly Four and turned Darkwing Duck against Negaduck's Forces.

The Negaverse Gosalyn that Negaduck adopted was just as rambunctious as her Counterpart adopted by Darkwing Duck himself until Negaduck brainwashed her into his Obedient Housekeeper.

The Negaverse Gosalyn had the Negaverse Morgana McCawber help her Brainwash the Friendly Four into Capturing Negaduck's Followers.

The Negaverse Muddlefoots and the Negaverse Launchpad McQuack went into hiding from the Brainwashed Friendly Four as the Negaverse Tank left for Darkwing Duck's help defeating the Negaverse Gosalyn.

Launchpad McQuack, Riku and Kairi found the Negaverse Tank passed out inside their Backyard the next day.

"The Negaverse Gosalyn has gone completely power hungry without Negaduck around to keep her under control... Gosalyn was Negaduck's Brainwashed Time Bomb, nobody saw Gosalyn's Behavior Transformation from Kindhearted Child into the Twisted Crime Lord coming until it was too late to stop her plans from happening." The Negaverse Tank explained in defeat.
