Close Combat hits opposing Steel-types such as Aggron and Ferroseed, OHKOing the former and 2HKOing the latter. Seed Bomb hits the Water-types that resist Perrserker's STAB Iron Head, OHKOing Quagsire and 2HKOing Jellicent. U-turn allows Perrserker to scout switch-ins and safely bring in a teammate. Double-Edge OHKOes Charizard and Centiskorch on the switch if running Tough Claws, two Pokemon that otherwise switch into Perrserker with ease. Tough Claws is the preferred ability on this set, as it powers up all of Perrserker's moves bar Seed Bomb. Steely Spirit can still be used, as it allows Perrserker to 2HKO Sandaconda and Palossand with a slightly stronger Iron Head. This set serves the dual roles of wallbreaker and offensive pivot. Against more defensive teams, Perrserker can use its massive power to smash defensive Pokemon like Regirock and Gigalith, as well as switching into predicted Stealth Rock and Toxic. Against offensive teams, it's best used to check physically frail Pokemon like Galarian Articuno and Ribombee, and it can use the forced switches to safely bring in a teammate with U-turn or fire off a strong attack. Fast Pokemon like Archeops and Choice Specs Ribombee are good teammates to threaten the more offensive teams Perrserker struggles with, while Perrserker can threaten the bulkier teams they struggle with. They all also appreciate the free switches Perrserker can give them with U-turn.
Swords Dance lets Perrserker break through most of PU's defensive Pokemon. Seed Bomb hits the Water-types that resist Iron Head, 2HKOing Quagsire and, after Swords Dance, OHKOing Lanturn and 2HKOing Jellicent. Substitute allows Perrserker to set up on weak walls like Ferroseed and Tangela, as well as dodging Weezing and Jellicent's Will-O-Wisp. Steely Spirit boosts Iron Head's power to massive levels, allowing it to 2HKO Weezing and Tangela at +2. Fire-types like Charizard and Centiskorch are highly problematic for this set, so Rock-types like Regirock and Gigalith are great teammates for checking them. Both can also set Stealth Rock for Perrserker. Charizard can scorch the Steel-types that wall this set like Ferroseed and defensive Togedemaru, and it appreciates Perrserker smashing the aforementioned Rock-types, as well as KOing Lanturn and Jellicent. Spikes setters like Garbodor and Qwilfish can help give Perrserker an easier time wallbreaking—one layer of Spikes guarantees an OHKO on Regirock with a +2 Iron Head. Both can also switch into the Fighting-types Perrserker is weak to, such as Hitmonlee. Fast cleaners like Archeops and Ribombee can take advantage of the holes Perrserker can punch in teams.
