Electrode

As one of the fastest Pokemon in the entire game, Electrode can roll into the battlefield and unleash swift hell with a handful of useful supportive and offensive options. It's no wonder that its silly grin can also be used as a lightning-fast Taunt to the foe's face, while its ability to call down the rain swiftly and effectively is a niche that only it can claim in the UU tier. Electrode's ability to summon down God's wrath in the form of Thunder makes it all the more terrifying. Combine Thunder with Hidden Power Ice and you've got a neat little Pokemon with great coverage. What makes Electrode even better is its access to Explosion, as unlike Uxie, Ambipom, and Omastar, it is able to immediately take down a dangerous threat while giving a safe switch-in for its Swift Swim buddies.

Unfortunately, the fun stops there. Electrode's mediocre stats across the board (excluding Speed) don't do it justice - it is fragile and, most of the time, doesn't hit hard enough. The fact that rain teams are dropping in usage, due to how easy it is to play around them via Pokemon such as Venusaur, Milotic, and Rotom, ruin Electrode's fame. Electrode's severely limited movepool outside of the ones already mentioned is the last nail in the coffin, sealing Electrode's fate as an almost-forgotten NU Pokemon. Still, once Electrode gets the ball rolling, there's really no stopping it.
