Moves

Psychic is Beheeyem's most reliable STAB move and hits physically defensive Pokemon such as Golem and Pyukumuku, whereas Psyshock functions as a slightly weaker option that allows it to threaten specially defensive Pokemon like Komala, Lickilicky, and Kecleon. Shadow Ball gives it a strong, super effective coverage move to hit Bronzor with and provides coverage for other Psychic-types such as opposing Beheeyem. Hidden Power Fighting gives Beheeyem an option to hit Pawniard and Probopass as well as some other Steel-types. It also provides super effective coverage for Dark-types and gives Beheeyem perfect neutral coverage when used with Shadow Ball. Another coverage option is Signal Beam, which gives Beheeyem a good chance to OHKO Silvally-Dark after Stealth Rock damage. Finally, Trick allows Beheeyem to cripple opposing walls and can make Beheeyem less reliant on predicting switches.

Set Details

Beheeyem's low Speed tier allows it to make frequent use of Analytic to power up its attacks. Its EVs are also invested into HP rather than Speed, as Beheeyem is unlikely to outspeed many threats even with investment, whereas HP allows it to take most attacks. 208 HP EVs minimize the damage Beheeyem takes from Stealth Rock, and 48 Speed EVs allow Beheeyem to outspeed Mareanie and uninvested Golem. This is important because Beheeyem excels at punishing a switch to Mareanie, and outspeeding Mareanie means Beheeyem can avoid Knock Off and OHKO with Psychic, or Psyshock if Stealth Rock is up.

Usage Tips

Beheeyem's primary objective should be to open holes in the opposing team that its teammates can take advantage of. It is very effective to bring Beheeyem in from a pivot or double switch, as this can bring it in at full health. If the opponent has no strong defensive checks, the most common scenario after doing this is that the opponent will choose a Pokemon to sacrifice and attempt to revenge kill—this means Beheeyem requires partners that are able to take on offensive Pokemon that threaten it to continue dealing damage. Beheeyem also has enough bulk to be brought in on a resisted move from an offensive Pokemon or a coverage move without a STAB bonus; examples of this include Mr. Mime's Psychic and Floatzel's Ice Beam. However, this is risky and can lead to Beheyeem becoming very worn down.

If the opponent is likely to switch to a defensive check that resists Psychic, like Bronzor or another Beheeyem, a prediction can be made to opt for use of Shadow Ball instead. This will 2HKO specially defensive Bronzor if it is brought in, which prevents it from setting up Stealth Rock or crippling Beheeyem with Toxic, as Beheeyem outspeeds it. Similarly, if the opponent has a Dark-type Pokemon like Silvally-Dark, a prediction can be made to use Hidden Power Fighting or Signal Beam. Trick should be used either to free up Beheeyem's predictions or simply to get rid of Choice Specs in the hope of crippling a foe if Beheeyem is no longer needed for wallbreaking. This is especially good for the entry hazard setters Shuckle and physically defensive Golem, as Beheeyem outspeeds them. After this, Beheeyem's final option is to make a trade. Beheeyem is unlikely to get KOed by any move that is not super effective with a STAB bonus but has a good chance of being able to KO the opposing Pokemon. Due to its low Speed, once it is placed on low health, it will likely lose most of its value but could still be used to KO even slower Pokemon like a boosted Curse Muk.

Team Options

Beheeyem appreciates Pokemon that can grant it safe entry; this is usually through pivoting, but Beheeyem also synergizes well with Pokemon that lure in defensive Pokemon so it can come in. An example of this is Silvally-Fighting, as it deals with Knock Off extremely well and can pivot with U-turn. Other Silvally formes like Silvally-Water and Silvally-Dragon are also strong choices, as they can also lure in defensive Pokemon and pivot. Beheeyem also appreciates trappers like Alolan Golem and Probopass because of their ability to remove Steel-type Pokemon, allowing Beheeyem to use its STAB Psychic more easily and more often. Probopass in particular is a good partner because it can bring Beheeyem in safely through a slow Volt Switch, and Beheeyem can check Fighting-types that threaten Probopass, such as Silvally-Fighting, in return. A good partner for Beheeyem is also Monferno, which is walled by Mareanie but can use U-turn to allow Beheeyem a particularly easy entry onto the field and also help Beheeyem deal with Bronzor and other Steel-types when Beheeyem has been locked into Psychic. Late-game cleaners synergize well with Beheeyem, as it can break through walls which may otherwise threaten them, which can allow them to win later on. Examples of this include Combusken, Swanna, and Electivire, all of which can make up for Beheeyem's lack of Speed and appreciate Beheeyem's ability to threaten Mareanie and Gourgeist-XL respectively.

Beheeyem appreciates entry hazard setters like Golem, as they can contribute damage and give Beheeyem a higher chance to OHKO a foe, such as Silvally-Dark with Signal Beam. Hazard removers also pair well with Beheeyem, as they can allow Beheeyem to avoid the damage it has to take when it switches in, thus possibly allowing it to withstand another hit and use another attack. Komala, Silvally-Fighting, and other Silvally formes are great for this. Beheeyem is strong on balance teams because it can often require a teammate to absorb damage when it needs to switch out on a revenge killer. This means it can synergize well with Pokemon like Altaria, Golem, and Gourgeist-XL.

Moves

Nasty Plot makes Beheeyem extremely powerful and threatening while still allowing it to use coverage and recover its health. Beheeyem can also opt to use Calm Mind, which allows Beheeyem to maximize its bulk and boost its Special Attack, making it too bulky for specially offensive Pokemon such as Floatzel and Electivire to safely handle while still having the offensive presence to deal with defensive Pokemon. Psychic is Beheeyem's preferred STAB move and handles physically defensive Pokemon better, whereas Psyshock handles specially defensive Pokemon such as Komala better. Using Psyshock and Psychium Z gives Beheeyem the opportunity to eliminate a physically bulky threat by targeting its Special Defense. Signal Beam is used as Beheeyem's coverage move to allow it to deal with Dark-types while maintaining a neutral hit on Bronzor and Pawniard. Optionally, Shadow Ball can be used instead of Signal Beam if the team is very weak to Bronzor. This still provides super effective coverage against Psychic-types but gives up coverage against Dark-types. Recover allows Beheeyem to use its bulk investment to stay on the field dealing damage. It also allows Beheeyem to set up against some offensive Pokemon and prevents it from getting chipped too much by bulky sweepers like Muk.

Set Details

Beheeyem runs Colbur Berry to stop it from being forced out by Dark-types, notably Pawniard and Silvally-Dark. Beheeyem can also run Psychium Z, which stops it from being crippled by Trick and Switcheroo and gives it the ability to use a devastating STAB attack or set up a Calm Mind through Taunt. As Psychium Z cannot be removed by Knock Off, it also gives Beheeyem a better matchup against Pawniard. Beheeyem prefers to run Defense EVs for a better matchup against most prominent threats. For example, it allows Beheeyem to always avoid the OHKO from Komala's Return and Pinsir's unboosted X-Scissor, and it softens damage from physical Floatzel and Golem, avoiding a 2HKO from variants that don't run Choice Band.

Usage Tips

Beheeyem can make use of its bulk and decent Special Attack to win matchups against some physically offensive Pokemon, and it takes advantage of balance, as it punishes the opponent for switching to a defensive Pokemon by setting up. This combination can make it very threatening for balance teams. The ideal time to use Nasty Plot or Calm Mind is when you predict the opponent will switch out their Pokemon in order to preserve it; even if Beheeyem lacks the power to OHKO the foe without any boosts, it is possible to bluff the Choice Specs set in order to force the switch necessary to set up. Beheeyem can take advantage of its high physical bulk and set up against some offensive Pokemon that do not run Toxic, and using Recover expands the number of Pokemon that Beheeyem can check because of its bulk and gives it more chances to set up. Beheeyem can also set up in order to act as a wallbreaker. However, it should be wary of Toxic while doing this. Unlike most sweepers, Beheeyem's role is not to punish a mistake and clean the rest of the opponent's team—it is too slow for this to be possible. Rather, Nasty Plot and Calm Mind allow Beheeyem to make some strong trades and get a lot of value, as it is usually able to take out a few Pokemon after a strong setup.

Team Options

Because Beheeyem is limited in the amount of coverage it can use on this set, it appreciates Pokemon that are able to handle its common checks. It also appreciates trappers like Alolan Golem and Probopass, which can remove Pawniard, and Silvally-Dark, which can remove Bronzor. It appreciates pivoting, particularly from Parting Shot, because this gives Beheeyem a good opportunity to set up while the enemy is weakened. Silvally-Fighting in particular synergizes well with Beheeyem, providing good offensive synergy, giving the team the ability to deal with Dark-types and Steel-types, and giving momentum via Parting Shot or U-turn. Komala is also a great partner for Beheeyem because it can absorb status and Ghost-type attacks. It can also provide momentum using U-turn, which gives Beheeyem an easy entry and opportunities to set up. In return, Beheeyem does a good job of dealing with Fighting-types, which threaten Komala. This ability to check Fighting- and Psychic-types also means Beheeyem synergizes well with other Pokemon like Golem and Combusken.

Moves

Trick Room is used to allow Beheeyem and possibly its teammates to gain a Speed advantage. This can allow Beheeyem to sweep the opposing team or set up the field for another Pokemon to come in that threatens the opponent's team. Psychic and Psyshock are Beheeyem's STAB moves—Psyshock can be used for better matchups against specially defensive Pokemon and Psychic for physically defensive Pokemon. Beheeyem runs Shadow Ball because it provides a way to hit Bronzor and threatens other Psychic-types. Hidden Power Fighting is useful for getting an OHKO on Pawniard as well as on Probopass after a tiny bit of chip damage. While using this, Beheeyem maintains perfect neutral coverage with Shadow Ball and keeps super effective coverage for Dark-types. Signal Beam is also a good coverage move, as it is super effective against Dark-types and Psychic-types; it deals more damage to Pokemon like Silvally-Dark compared to Hidden Power Fighting and does a better job of threatening Grass-types like Exeggutor.

Set Details

Life Orb maximizes Beheeyem's damage output while allowing it to freely use coverage and switch moves, whereas Colbur Berry gives Beheeyem a stronger matchup against Dark-types and can allow Beheeyem to take on Dark-types such as Pawniard and Silvally-Dark with appropriate coverage. The third option, Psychium Z, gives Beheeyem a one-time powerful STAB attack to break through bulky Pokemon. When coupled with Psyshock, Beheeyem is able to target both specially and physically defensive Pokemon. It also allows Beheeyem to use Trick Room through Taunt and prevents Beheeyem from being locked into Trick Room by Trick or Switcheroo. Beheeyem runs 0 Speed IVs to ensure it will outspeed the foe under Trick Room. Beheeyem can choose to run 8 IVs in Speed, allowing it to outspeed Bronzor and threaten to 2HKO under Trick Room with Life Orb Shadow Ball due to Analytic. Under Trick Room, Analytic may not activate, but the situations where Beheeyem prefers to attack still make Analytic the better ability to use. Synchronize is unreliable and does not help Beheeyem to fill its role as a wallbreaker.

Usage Tips

On a full Trick Room team, Beheeyem should be used to simultaneously set up Trick Room and take advantage of it—its bulk should allow it to take at least one hit to set up Trick Room for itself and its team. On balance or hyper offense, Trick Room can be used to allow Beheeyem to become a sweeper that synergizes with other slow Pokemon on the team. On these teams, Trick Room should be used cautiously, as it could give the opponent an advantage. Beheeyem functions best as a Trick Room sweeper if most of its checks are removed; its coverage allows it to deal with a lot of Pokemon that resist Psychic, but switching between coverage moves can waste Trick Room turns. Beheeyem can potentially countersweep the opposing team if it has enough turns to do so and no strong checks are present, and it can also be used solely to allow another Pokemon to sweep through Trick Room if the situation demands it.

Team Options

On a standard Trick Room team, Beheeyem appreciates partners that can set up Trick Room for itself and other attackers on the team. Carbink and Dusknoir are two solid options for setting Trick Room reliably so Beheeyem can utilize it in order to deal a vast amount of damage. Trick Room attackers that pair well with Beheeyem include Wishiwashi and Marowak, which are common options on a full Trick Room team, and Golem and Granbull, which work well outside of these full Trick Room teams. Granbull in particular synergizes well with Beheeyem, as Trick Room can enhance its ability to wallbreak and open holes in the enemy team. It also has a good matchup against Dark-types and Intimidate to take a hit if Beheeyem is forced out. Outside of full Trick Room, Beheeyem also appreciates the utility provided by entry hazard setters such as Golem and Crustle as well as pivots like Komala that help it find opportunities to set up Trick Room. Beheeyem works best with Pokemon that take care of the very few checks it has. For example, if Beheeyem is not running Hidden Power Fighting, Pokemon such as Silvally-Fighting and Golem can be useful in a matchup against Probopass and Pawniard.
