Passimian

Passimian is a good Fighting-type in RU because it can act as a pivot, cleaner, and wallbreaker while also having good bulk to act as an offensive switch-in to the Bug-, Rock-, and Dark-types of RU such as Golisopod, Tyrantrum, and Drapion, as well as taking hits from Mega Blastoise and Virizion. It has a solid Speed tier that allows it to be faster than other Fighting-type wallbreakers like Bewear, Machamp, and Virizion with a Choice Scarf. Passimian is also the only viable Fighting-type with U-turn, making it a successful pivot and giving it a unique place among the sea of Fighting-types in RU. Defiant allows it to pressure Defog users such as Mandibuzz and Mantine as well as Sticky Web users such as Araquanid and Galvantula by boosting its Attack, so it can keep its team's entry hazards in battle. However, Passimian can't hit everything it wants in one moveset for super effective damage and its reliance on Choice items mean that Pokemon such as Slowbro, Golisopod, and Gardevoir can easily pivot against it if it goes for its Fighting-type STAB attack, making it somewhat easy to take advantage of.
