Its round face and smooth coat—softer than the most high-class velvet—have made this a very popular Pokémon in Alola.
– Pokémon Sun Pokédex
Alolan Persian is Dark type instead of Normal type. I personally really dislike its design; mostly, how round its face is… it looks like it doesn’t belong on its body. Though according to its Pokedex entries, the roundness of its face is what makes it a popular pet, despite its brutal behavior, and that “Its round face is a symbol of wealth. Persian that have bigger, plumper faces are considered more beautiful.”
One of its abilities is Fur Coat, which was previously exclusive to Furfrou. It doubles its Defense stat, which makes its 60 defense actually useable.
Stat-wise, it has good Speed, and average other stats. Compared to Kanto Persian, it has 10 less Attack for 10 more Sp Attack, making its Sp Attack higher than its Attack, which is a bit awkward since most of its level-up moves are physical (Dark has a lot more physical options than special options). Though it can learn Nasty Plot, and Dark Pulse.
