The level-up pool is slim, so TMs matter here. Dustox's Psychic and Flying coverage and more all comes from technical machines, built on top of Sludge Bomb and Silver Wind for same-type damage. Hyper Beam and Psychic are the payoff moves.

  • Dustox works as a support with 385 BST behind it. D-Tier on our list — outclassed by better options in most formats.

  • Watch for Blaziken (Fire), Dodrio (Flying), and Gardevoir (Psychic) when using Dustox. They all hit it super-effectively with STAB. Rock-type attackers are also a problem.

  • Cascoon evolves into Dustox at level 10. Dustox is the final evolution in a 5-stage line starting from Wurmple.

  • Shield Dust protects against incoming moves' extra effects — that's the one you want on Dustox. Compound Eyes is the hidden ability. Niche, but it has its uses.

  • Dustox is a physical attacker with base 50 Attack. Enough bulk to take a hit or two, too. But the speed tells the real story — at base 65 Speed, it won't be moving first often. Fits the support role.

  • Dustox appears in 14 games, including Ruby & Sapphire, FireRed & LeafGreen, and Emerald.

Debuting in Ruby & Sapphire, Dustox appears in 14 games across 7 generations. A reliable presence in a solid number of games, typically found through wild encounters.
