Major Synapse

Major Synapse was a canine military officer in charge of FOWL's so-called psychic division. Originally, he was the commander of FOWL's military until an incident in which he marched several troops (possibly FOWL Eggmen) to their deaths in an erupting volcano in an attempt to secure it for an unknown reason. Synapse hated his new position, because he wanted to command disciplined, competent troops, but the only members in the psychic division, a couple of hippies, were the exact opposite. With an unnamed tracking device, Synapse and the hippies tracked psychic vibrations which lead them to SHUSH's secret laboratory in the Alps.

There, Synapse stole Dr. Sarah Bellum's invention, the Norma Ray. The Norma Ray was designed to help give an individual who was zapped by it psychic powers, but they can't think while being zapped or the head will explode. Synapse used the Norma Ray to give the hippies psychic powers. The male hippie called himself "Hotshot". He had the power to burn or freeze anything in his path. The female hippie had the power of telekinesis and called herself "Flygirl". With their new superpowers and Launchpad's inability to control his new psychic powers, Synapse and his "troops" defeated and captured Darkwing Duck.

Back in their hideout, Synapse had Darkwing encased in a giant ice cube. He planned to kill him by flattening him with a giant anvil held up by Flygirl. However, instead of having the deed done, Synapse ransomed the Hero's death to FOWL High Command, with a variety of inane demands, like a personal parking space for his tank.

His arrogance led to a delay, which resulted in Darkwing getting rescued by Gosalyn and Launchpad. Hotshot and Flygirl wound up being flattened by the anvil instead. Synapse used the Norma Ray on himself so he can think of a way to defeat Darkwing. Launchpad warned him not to think before he used it. Synapse overdid it and became a being of pure thought, a disembodied head with a huge brain.

In this form, he was unstoppable. But then Darkwing used the Norma Ray on him while he, Gosalyn, and Launchpad asked him rapid fire questions, causing him to think during the blasting process, causing him to explode, killing him.

He was one of two villains to actually die onscreen. The second to die was Splatter Phoenix.
