Arbok punches above its weight class thanks to Intimidate. It lowers the opponent's Attack on switch-in, which is enough to make up for stats that don't impress on their own. Only weak to Ground and Psychic. Known as the Cobra Pokemon.

Arbok's spread isn't flashy. Attack leads, HP trails, 2 stats clear the bar. Moderately hard to find and worth 2 Attack EVs, on a medium-fast 1M XP curve.

The TM pool is where it gets interesting. Coverage across 10 types means almost nothing walls Arbok cleanly, with Gunk Shot and Sludge Bomb anchoring the STAB side. Matchup flexibility isn't a problem.

    or evolve from Ekans (Step 1)
  • Don't let Arbok's 448 base stat total fool you. Intimidate is what makes it tick — it punches way above its weight class. We rate it C-Tier.

  • Arbok's biggest threats include Golem (Ground) and Starmie (Psychic), all carrying super-effective STAB moves. Only 2 weaknesses means fewer dedicated counters to worry about.

  • Ekans evolves into Arbok at level 22. Arbok is the fully evolved form. It sits at 448 BST in its evolved form.

  • Run Intimidate on Arbok. It's the ability that defines how you build around it and the main reason it holds a competitive niche. Arbok also gets Shed Skin and Unnerve, but they don't compare.

  • Arbok fills the balanced role. It's leaning toward the physical side (base 95 Attack). Base 80 Speed is workable — faster than some, slower than many. And it's enough bulk to take a hit or two.

  • Arbok appears in 20 games, including Yellow, Red & Blue, and Gold & Silver.

Arbok has been part of the series since Red & Blue, appearing in 20 titles across all 9 generations. As a Gen 1 original, it's one of the most consistently available Pokemon in the franchise.
