Moves
Close Combat obliterates Normal-, Rock-, Steel-, Dark-, and Ice-types, as well as dealing huge amounts of damage to neutral targets. For example, it OHKOes Assault Vest Lanturn, Hitmonchan, Magmortar, Lilligant and Ludicolo from full HP. U-turn is one of Primeape's biggest niches over other Fighting-types, allowing it to maintain momentum while also hitting Psychic-types such as Musharna, Mesprit, Malamar, and Claydol super effectively. Stone Edge lets Primeape hit Flying-types such as Scyther, Rotom-S, and Xatu extremely hard if they switch in. Earthquake primarily hits Garbodor, which is otherwise very problematic, as it can wear down Primeape with Rocky Helmet. Earthquake also KOes Skuntank without triggering Aftermath. Alternatively, Ice Punch gives Primeape a way to hit Vileplume, Gourgeist-XL, and Torterra hard while providing coverage against Flying-types at the cost of being unable to OHKO Scyther. Gunk Shot is an option to 2HKO defensive Mega Audino and OHKO mixed defenses Clefairy.
Set Details
Primeape sports a standard offensive spread with maximum Attack and Speed investment to hit as hard and be as fast as possible. Jolly is the preferred nature, as an Adamant nature doesn't help it score any extra notable OHKOs and leaves it vulnerable to base 90 Speed threats such as Lilligant and Mr. Mime. With a Jolly nature, Primeape outspeeds positive-natured base 90 Speed Pokemon and below, such as Lilligant, Vivillon, Kangaskhan, Mr. Mime, and Zangoose, and Speed ties with base 95 Speed Pokemon, including Jynx, Haunter, and offensive Xatu. With a Choice Band, Primeape's Attack stat rises to extremely threatening levels, giving it significant wallbreaking power. Defiant allows Primeape to pivot into and punish Defoggers such as Pelipper and Mantine with a +2 Stone Edge. Alternatively, Vital Spirit lets Primeape absorb Sleep Powder from Lilligant and Vivillon and Spore or Dark Void from Smeargle.
Usage Tips
Primeape thrives in VoltTurn cores, which enable it to switch out of its counters and come into battle unscathed, as it does not have the bulk to switch into even neutral hits. After coming in, Primeape should be played as a wallbreaker that can punch holes in the opponent's team and make way for a teammate to sweep. Close Combat is Primeape's most spammable move, but if the opponent has a Fighting-type switch-in such as Vileplume or Gourgeist, it's best to simply use U-turn to gain momentum. Sometimes clicking the appropriate coverage move, such as Stone Edge on a predicted Scyther switch-in, can gain a huge amount of momentum, but it is important to weigh the risk versus the reward, as Primeape does not have the bulk to stomach hits if a prediction is wrong. Finally, Primeape's presence alone can be enough to deter the use of Defog due to the threat of Defiant, but if it seems likely that the opponent will use it, pivot Primeape in and punish them for doing so.
Team Options
Primeape fits best on VoltTurn offense; Volt Switch and U-turn users such as Rotom, Lanturn, Scyther, Xatu, and Manectric are all spectacular partners that can keep up momentum and help wear down one another's checks. Spikes-stacking support from Garbodor and Ferroseed pairs extremely well with Primeape, as Primeape can wear down its checks through pivoting with U-turn more effectively and, as a bonus, act as a Defog deterrent to keep hazards up. Pursuit trappers such as Skuntank and Liepard are amazing partners, trapping the bothersome Psychic- and Ghost-types that prevent Primeape from spamming Close Combat. Furthermore, speedy late-game sweepers such as Floatzel, Swellow, Archeops, and Choice Scarf Jynx work well in conjunction with Primeape's wallbreaking capabilities and can take on faster threats such as Charizard, Tauros, Pyroar, and Scyther in return. Additionally, Fire-types such as Magmortar and Pyroar can pivot into Will-O-Wisp from Weezing and Mismagius and appreciate Primeape's ability to break down their checks such as Assault Vest Hariyama, Regirock, Rhydon, and Lanturn.
