- This Pokémon is immune to Ground-type moves.
Level 100 Statistics (see level 5, 50, 100)
Despite being largely outclassed by Mismagius, access to toys that Mismagius lacks makes Haunter a solid addition to any UU team. Hypnosis and Explosion are important moves in Haunter's repertoire that Mismagius would love to learn, but what sets Haunter apart from Mismagius is his higher Special Attack stat and good secondary STAB in the form of Sludge Bomb. However, one must not forget Haunter's downsides. His defenses makes Sharpedo look bulky, and his Speed is good but often not good enough. Do not play Haunter like a down-sized Mismagius and he will be happy.
This set aims to make full use of Haunter's advantages over Mismagius. With a Life Orb attached, Haunter's Shadow Ball hits almost as hard as +1 Mismagius, making him very difficult to wall without resorting to Registeel. This set is relatively simple to use. Come in on a Pokemon that Haunter can force out and set up a Substitute. From there, proceed to smack the opponent with STAB attacks coming from a base 115 Special Attack. Sludge Bomb is a huge selling point for this set, since it allows Haunter to hit Normal-types that are immune to Shadow Ball, such as Miltank and Clefable, very hard. However, if one wishes to take a chance, Hypnosis is always a reasonable option to incapacitate a counter.
The last move is the most variable. Hidden Power Ground is preferred since it allows Haunter to hit Drapion and Skuntank (two of Haunter's biggest counters) for super effective damage. It can also hit Registeel on the switch for more damage than any of its other moves. Thunderbolt is generally a good move, since it has good coverage alongside Shadow Ball and Sludge Bomb, while having the added bonus of being able to 2HKO Milotic and Blastoise. It also allows Haunter to revenge kill Moltres should the need arise. Finally, Explosion can be used to allow Haunter to go out with a bang and potentially remove a counter, thus allowing a teammate to sweep.

This set aims for Haunter to sustain a longer sweep by using Pain Split. While Mismagius mostly does this better, Haunter still has some notable advantages over his Ghost-type relative. Haunter's higher base Special Attack makes him much harder to wall. Haunter's lower HP stat also allows him to heal more from Pain Split than Mismagius does. The idea of this set is Substitute on an opponent that cannot hurt Haunter. After this, proceed to bombard with your opponent with powerful attacks. When Haunter's health becomes low, use Pain Split and steal HP from the opponent. Shadow Ball is Haunter's bread-and-butter STAB move, and hits anything that does not resist it for a lot of damage. Hidden Power Ground is the preferred option for Haunter's coverage move, since it hits more of his counters like Drapion and Registeel for super effective damage. On the topic of Registeel, it has a much harder time defeating Pain Split Haunter, since Haunter can Substitute down to low health and Pain Split Registeel down to the Hidden Power Ground 2HKO range. Thunderbolt offers greater neutral coverage than Hidden Power Ground and is a better attack to KO Milotic and other bulky Water-types.

Haunter has plenty of special attacks in his arsenal. Energy Ball can be used to hit Lanturn. Icy Wind is an interesting option, as it allows Haunter to hit some faster switch-ins and lower their speed, allowing for a KO on the next turn. Different Hidden Power types such as Fire and Fighting can be used, but are generally not as effective as Hidden Power Ground. Haunter also has access to various support moves like Taunt, Will-O-Wisp, and Curse, but is much too frail to put them to good use.
Haunter can also make decent use of Choice Specs or Choice Scarf, being able to cripple many of its switch-ins with Trick, but is generally too frail and cannot find time to switch in. Also, Mismagius tends to use Choice sets better.
Checks and Counters
Specially defensive Spiritomb, Registeel, Clefable, Drapion and Skuntank are by far the best counters available to combat Haunter, but all need to be wary of being put to sleep by Hypnosis. Registeel also needs to watch out for Substitute + Pain Split. If Toxic Spikes are not up, Chansey can Life Orb stall the Substitute + 3 Attacks set so long as Haunter is not carrying Explosion. Otherwise, Haunter is not very difficult to revenge kill. Should Haunter not have a Substitute up, Alakazam can outspeed and OHKO with Psychic. Swellow, Ambipom and Tauros can switch into any attack not named Sludge Bomb or Thunderbolt and OHKO with Pursuit, regardless of whether Haunter stays in or not. Mismagius can outspeed and OHKO with Shadow Ball so long as she avoids Haunter's Shadow Ball.
