Samurott is so cool. IDK why people say it ruined oshawott. Look at it. Magnificent 4-legged beast who can stand on 2 at will, massive horn, ability to wield swords.
It's kind of like Dragonite, everyone expected this badass two-legged sea otter and we're thrown off by Samurott. To be fair though, Samurott is at least more closely related to the theme of the other two.
