Electric moves don't affect Nidoking at all — that's the advantage of Poison/Ground typing. It sits at a decent but contested Speed tier. Known as the Drill Pokemon. Flexible enough to run physical or special sets.

Attack and Sp. Atk carry most of Nidoking's stat budget. Sp. Def's the obvious dump stat. Tough to catch and yields 3 Attack EVs. Follows a 1.06M XP medium-slow curve.

Nothing fancy here. Nidoking builds around an item for extra utility, a nature nature for the right stat lean, and flexible EVs EVs. An ability does its job quietly.

TMs carry this one. Nidoking learns Earthquake and Poison Sting naturally for STAB, but the offensive range comes almost entirely from technical machines. Normal and Ice and beyond give it real matchup play.

    or evolve from Nidoran♂ (male) (Step 1)
  3. Nidoking
    Step 3Nidoking ✓

  • Sheer Force changes the entire equation for Nidoking. The 505 BST doesn't tell the full story. Ranked C-Tier as an attacker.

  • Nidoking's biggest threats include Gyarados (Water), Cloyster (Ice), and Golem (Ground), all carrying super-effective STAB moves. Psychic and Bug-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter.

  • Nidorino evolves into Nidoking using a Moon Stone. Nidoking is the final evolution in a 3-stage line starting from Nidoran M. At 505 BST, it's got solid stats to work with.

  • Base 85 Speed is workable — faster than some, slower than many. On offense, Nidoking is a mixed attacker — base 102 Attack and 85 Sp. Atk. Defensively? Enough bulk to take a hit or two. Best used as an attacker.

  • Nidoking appears in 19 games, including Yellow, Red & Blue, and Gold & Silver.

One of the original 151, Nidoking has appeared in 19 games — most mainline games. From Red & Blue through the latest titles, it's rarely been left out of a regional Pokedex.
