The Evil Trio is a trio of legendary Pokémon introduced in Pokémon Sun & Moon Versions. It consists of Wizmos, Beastmos, and Skulmos. It is led by Deimos. All four were said to have been destroyed by Mysteacle after attempting to seize his power over the Atora region.
Evil Trio is a collective fan term used to refer to the Legendary trio of Wizmos, Skulmos, and Beastmos. Other fan terms include Mos trio and Demons.
Like the Swords of Justice, the demons share share the same suffix -mos, and their types seem to be based on a more darker side of Pokémon lore. Like them, however, these three have a trio master in Deimos.
Also shared among the members of this trio is their primary type, Dark. Unlike most legendary trios, the demons do not have Pressure as their Ability, though they do share the Ability Dark Soul.
Legend spoke of Deimos searching the world for an army to defeat Arceus with, but was only able to find the three demons. As a result, it took them in and raised them in order to become the darkest of Pokémon with no pure heart. In order to prevent them from wreaking havoc on the world, humans defeated them in riot and sealed them away for good.
Trivia
- The Evil Trio is strikingly similar to the Ulfuria region's Darkness Trio; both trios have Dark as their primary type and Fighting, Psychic and Ghost as their secondary types.
