Feebas evolves into Milotic, but why? Can someone explain?
As its name suggests, Feebas is probably based on a bass, possibly the largemouth bass. It also resembles the marine hatchetfish. Its ugly appearance makes it appear to be also based from the concept of ugliness, appearing to don a wash of ugly makeup. It also seems to be based on the classic fairy tale, The Ugly Duckling, where a small and feeble "ugly duckling", treated as an outcast by other animals, blossoms into a beautiful swan.
