Linoone

In the depths of the RU tier lies an often overlooked Pokemon, one that trainers typically wouldn't hesitate to release after the first gym. This Pokemon is none other than Linoone, and while it may seem cute and harmless, it's anything but. After one turn of setup with its rare boosting move, Belly Drum, Linoone can easily tear most teams to pieces. What's more, due to STAB Extreme Speed, it's less vulnerable to being revenge killed than other Belly Drummers after a boost. Linoone is not unstoppable, however; there are plenty of Pokemon that can put its rampage to a stop. Linoone also needs some help to begin its sweep in the first place, as it is incredibly frail. If you can provide Linoone with the support it needs to unleash its potential, however, it won't hesitate to drive your opponent up a tree, in fear that is.
