Under Trick Room, Beheeyem's terrible Speed becomes its best asset — it 'outspeeds' nearly everything when turns are reversed. And it hits hard enough to make that matter. Only weak to Bug, Ghost, and Dark. Been around since Gen 5.
Beheeyem's all-in on Sp. Atk at the expense of Speed. The special lean is obvious from the bars. Yields 2 Sp. Atk EVs and follows a medium-fast 1M XP curve.
With its psychic powers, it rewrites its opponents’ memories. You, too, may have already had your memories rewritten.
It has strong psychic powers. Using its fingers that flash three different colors, it controls its opponents and rewrites their memories.
Beheeyem Weakness
VulnerableType-wise, Beheeyem takes extra damage from Bug, Ghost, and Dark. With 75 HP and balanced defenses, Beheeyem can afford to eat a neutral hit or two.
Beheeyem is the evolved form of Elgyem. Breeding produces Elgyem eggs, and they're average hatch time. Evolving from Elgyem gave Beheeyem the biggest boost in Sp.Atk (+40), bringing the total to 485 stats.
How to Evolve
Breed with Beheeyem to get Elgyem eggs easily from the Humanshape egg group. Notable egg moves include Ally Switch, Astonish, Barrier and 7 more.
This build takes hits and hits back. Leftovers provides passive recovery each turn, Telepathy supports the gameplan, and max HP and Sp. Atk EVs mean Beheeyem doesn't crumble to chip damage. Plus the remaining moves backing it up.

Breeding's the move. Ally Switch and Astonish give Beheeyem options it can't learn any other way, and coverage across 8 types already covers a decent range on top of Synchronoise and Dream Eater. The egg moves push it further.

Step 2Beheeyem ✓
Beheeyem has a 485 base stat total and ranks as C-Tier — a situational pick that fills a niche. It works best as a wallbreaker. Base 125 Sp. Atk is where it shines.
Beheeyem's biggest threats include Scyther (Bug), Chandelure (Ghost), and Weavile (Dark), all carrying super-effective STAB moves. At base 40 Speed, Beheeyem won't outrun any of these threats so switching to a resist is usually the safer play.
Elgyem evolves into Beheeyem at level 42. Beheeyem is the fully evolved form. At 485 BST, it's got solid stats to work with.
Telepathy is the go-to ability for Beheeyem. It protects against friendly Pokémon's damaging moves. Its hidden ability Analytic can work in specific setups. Synchronize is the other option — pick based on what your team needs.
Beheeyem fills the wallbreaker role. It's a special attacker with base 125 Sp. Atk. Base 40 Speed is low. Priority moves or Trick Room are the way to go. And it's enough bulk to take a hit or two.
Beheeyem appears in 7 games, including Black & White, Black 2 & White 2, and X & Y.
Introduced in Black & White, Beheeyem has appeared in 7 games across 5 generations. Later debuts mean fewer total appearances, but it's been a consistent presence since its introduction.
