Milotic, the Tender Pokémon. Milotic is able to soften human anger and hatred by emitting soothing frequencies from its body.
– Ash’s Pokedex
Milotic is considered to be one of the most beautiful Pokemon. Despite being based on Venus de Milo (at least name-wise) and looking rather feminine, Milotic has a 50% change of being male.
Its evolution condition is unique; it evolves by level-up when Feebas’s Beauty condition is high. I’ve never really bothered with contests or Beauty conditions though. In Gen V, since there’s no contests anymore, it evolves by traded while holding a Prism Scale, which is much easier I think.
Milotic is almost like the mascot for contests, since it’s introduced at the same time as contests were. Furthermore, in the anime, Wallace, the top contest coordinator, has a Milotic that’s always with him.
Stat-wise, it has good Sp Defense and HP, which makes it a good special wall. It also has good Sp Attack and decent Speed. It lacks a bit in Defense, but its ability Marvel Scale raises its Defense by 50% if it has a status ailment.
