Chi Yu

Chi-Yu poses itself as one of the most menacing special attackers in DOU, with its high Special Attack, near unresisted STAB combination, and Beads of Ruin allowing it to hit the majority of the metagame extremely hard. Beads of Ruin also not only indirectly makes Chi-Yu hit harder but also empowers its special attacking teammates, with Iron Bundle and Gholdengo in particular being excellent partners due to their ability to either overwhelm shared checks like Ting-Lu or outright beat some of Chi-Yu's checks, such as Garchomp for the former and Glimmora for the latter. Furthermore, Chi-Yu has very good Speed, allowing it to naturally outspeed a considerable portion of the metagame. However, Chi-Yu is not without glaring weaknesses, as its HP and Defense are absurdly low, which leaves it vulnerable to common priority moves such as Palafin's Jet Punch and Dragonite's Extreme Speed. In addition, despite Dark / Fire being a good type combination offensively, it leaves Chi-Yu vulnerable defensively, as its weaknesses to Ground-, Rock- and Water-type moves in addition to Stealth Rock compromise its ability to switch in and fire off more attacks. Finally, Pokemon such as Glimmora, Ting-Lu, and Garchomp have the ability to potentially switch into Chi-Yu and threaten it out, with Ting-Lu's Tablets of Ruin being a particular annoyance due to it offsetting Beads of Ruin. However, it is important to note that Chi-Yu's strength is still to the magnitude that it can 2HKO all the aforementioned Pokemon under the right circumstances.
