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 Leftovers for passive recovery each turn, a nature nature for the right stat lean, and flexible EVs EVs. An ability does its job quietly.

Hard to wall, honestly. Nidoking threatens 11 types beyond its own STAB, with Fighting and Normal standing out. Pair that with Earthquake and Mud-Slap and switchins need to think twice.

    Step 3Nidoking
  • Sheer Force changes the entire equation for Nidoking. The 505 BST doesn't tell the full story. Ranked B-Tier as an attacker.

  • Nidoking's biggest threats include Gyarados (Water), Cloyster (Ice), and Golem (Ground), all carrying super-effective STAB moves. Psychic-type attackers are also a problem.

  • 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.
