Nidoking can use one of two Abilities: Poison Point, which Poisons an opponent that uses an attack that requires physical contact against it at a rate of 30%; or Rivalry, which increases its Attack and Special Attack by 25% if its opponent is also male, but decreases those same Statistics by 25% if the opponent is of the other gender. Its Hidden Ability is Sheer Force, which increases the power of moves that have a secondary effect by 33%, but those secondary effects are lost as a result.
Nidoking takes on the appearance of a large, scaly purple lizard. In addition to its horn, which is poisonous, it also has poisonous barbs on its ears, head and back. Nidoking also has a lengthy tail, which can be swung about with tremendous force.
Nidoking is a Male-Only Pokémon species and is the male equivalent of Nidoqueen.
Nidoking cannot be found in the wild and can only be obtained by evolving a Nidorino, which is consistent across all of its game appearances.
Nidoking makes appearances at Endless Level 2, Pair Trozei, Forever Level 51 and Mr. Who's Den in Pokémon Trozei!.
The only way to obtain a Nidoking in the first set of Mystery Dungeon games is to evolve a Nidorino. In Explorers of Time, Explorers of Darkness and Explorers of Sky, Nidoking can be found at Shimmer Desert 1F-9F, which is known as Shimmering Desert in Explorers of Sky but the floor range is the same. Nidoking is exclusive to Light Adventure Squad in Mystery Dungeon 3, appearing on the Path to Treasure Island B1-B5.
Nidoking has yet to appear in any of the Pokémon Ranger games as of writing.
Nidoking can be found at Shimmering Lake Cave 2-4 in Pokémon Rumble Blast.
Trading Card Game
Nidoking is listed nine times in eight sets. He is listed as a Rare Card in the Base, Gym Challenge, Aquapolis (2), EX FireRed and LeafGreen, EX Dragon Frontiers (Delta Species Card), Secret Wonders, Rising Rivals and Triumphant sets.
Gary would use a Nidoking in the episode The Battle of the Badge, defeating Giovanni's Golem to start the Gym Battle, only to get easily defeated by Mewtwo. He would also use his Nidoking in Fourth Round Rumble, this time losing to another trainer's Golem.
A wild Nidoking would go on a rampage because of Team Rocket in In The Pink. He would have no problem dispatching Team Rocket, but Ash and company would attempt to flee with the help of Officer Jenny. They get cornered, only for Misty's Togepi to use Metronome, reflecting an incoming Hyper Beam with a Barrier.
Gary's Nidoking makes an appearance in a flashback in Mewtwo Strikes Back, and another trainer uses a Nidoking in Lucario and the Mystery of Mew. Wild Nidoking make an appearance in The Power of One, Celebi: Voice of the Forest and Arceus and the Jewel of Life.
Red would capture a few Nidoking in Chapter 21, which would make a subsequent appearance in Chapter 22.
Giovanni uses his own Nidoking in Chapter 38 when Red challenged the Viridian City Pokémon Gym. This Nidoking would make a subsequent appearance in Chapter 275.
Nidoking is in the Underused (UU) tier of competitive battling. With great offensive prowess due to Sheer Force boosting its special attacks and preventing Life Orb recoil, Nidoking is certainly a capable special attacking threat. Its strong STAB attacks in Sludge Wave and Earth Power can dish out significant damage to the majority of the tier, while it can run Superpower to break through defensive behemoths like Blissey and Snorlax. It can also provide Stealth Rock support decently well if need be. However, Nidoking suffers from being in a subpar Speed tier that makes it easy to revenge kill. It also faces competition from Nidoqueen, which is bulkier and can hit harder than Nidoking with a Modest nature due to Nidoking usually having to use a Speed boosting nature in order to take advantage of its higher Speed in comparison to Nidoqueen.
Nidoking is also an option in the Overused (OU) tier of competitive battling. Due to a great offensive movepool bolstered by Sheer Force, Nidoking can be quite the formidable wallbreaking threat. Its Poison / Ground typing allows for it to switch into Clefable, while its coverage options such as Ice Beam and Flamethrower can throttle supposed defensive checks. Despite being able to check one of the most prominent Pokémon in the tier, Nidoking has flaws like being outpaced by many Pokémon in the tier and having lackluster bulk that prevent it from being a top-tier threat. It also faces heavy competition from many other wallbreakers like Manaphy, Kyurem-B, and Mega Alakazam, all of which can bring more to the table due to better bulk, Speed, or power.
