Haunter

GhostPoison
Available for SV PLZA SWSH BDSP PLA LGPE
Order Haunter — free

Haunter is a Ghost/Poison-type Pokémon (National Dex #93) with a middling stat total of 405. You can have one built for Scarlet & Violet, Legends: Z-A, Sword & Shield, BDSP, Legends: Arceus and Let's Go, and every copy is generated through the same PKHeX legality engine Pokémon HOME uses on deposit.

Its best stat is Sp. Atk at 115, which makes it a slow but heavy-hitting attacker. Special Attack outweighs Attack by a clear margin, so Modest or Timid with a special move set is the natural build. When you order one here you pick the nature, EV spread, IVs and Tera type yourself, so you can build the exact spread the set calls for rather than breeding for it.

Defensively, Haunter takes super-effective damage from Ground, Psychic, Ghost, Dark. It is completely immune to Normal, Fighting. It resists Grass, Poison, Bug, Fairy. Its ability options are Levitate.

Haunter evolves into Gengar. You can order any stage directly rather than raising it — useful when you want the final evolution at a specific level, or the pre-evolution with an egg move it can only learn early.

In-game, Haunter has 175 recorded encounter locations across Scarlet & Violet (57), Legends: Z-A (31), Sword & Shield (16), BDSP (51), Legends: Arceus (8), Let's Go (12) — listed in full below with levels, catchable marks and legal Poké Balls. Note that at least one encounter is shiny-locked in Legends: Z-A, Sword & Shield, BDSP, meaning it cannot be found shiny there no matter how long you hunt. A shiny Haunter ordered here is built with a legal PID and Encryption Constant, so it passes the same checks a hunted one does.
