JUSTIFICATIONS:

Meowstic: "The eyeball patterns on the interior of its ears emit psychic energy. It keeps the patterns tightly covered because that power is too immense"

so literally Mob

Mimikyu: "A lonely Pokémon, it conceals its terrifying appearance beneath an old rag so it can get closer to people and other Pokémon."

cute and shy and just wants friends

Arcanine: "Its proud and regal appearance has captured the hearts of people since long ago"

Reigen the perfect doggo

Lucario: "Not only does it perceive auras, but it has also gained the power to control them. It employs them in battle."

everything Mob wishes he could be (i.e. able to read people) but also what he can do (manipulate auras)

Alola Ninetales: "Possessing a calm demeanor, this Pokémon was revered as a deity incarnate before it was identified as a regional variant of Ninetales."

Mob is worshipped as Psycho Helmet but he's just a kid

and Mewtwo just generally being angry and hateful and scorned

because Mob has reached out to those who are vicious, dangerous, lonely... and befriended all of them (Teru, Serizawa, boss Suzuki)

(and Dimple kinda lmao)
