Mid-stage Pokemon like Nidorino rarely see competitive play outside of special formats. It's a waypoint on the road to Nidoking, which is where the real potential kicks in. Only weak to Ground, Psychic, and Bug. Known as the Poison Pin Pokemon.
Nidorino's stats barely vary. 0 sit in respectable range with no real gaps. It's a blank slate for EV investment. Worth 2 Attack EVs, 1.06M XP medium-slow curve to max.
Its horns contain venom. If they are stabbed into an enemy, the impact makes the poison leak out.
Nidorino Weakness
VulnerableGround, Psychic, and Bug-type moves hit Nidorino for super-effective damage. 3 weaknesses is about average, nothing too hard to play around.
- Only 15 types exist — Dark, Steel, and Fairy are absent
- Ghost has no effect on Psychic (a known bug, fixed in Gen II)
- Special stat governs both offense and defense — no Sp.Atk / Sp.Def split
Partway through Nidoran♂ (male)'s chain, Nidorino is a Poison type pushing toward Nidoking. No breeding at this stage. So far, Defense got the biggest boost (+17 from Nidoran M). The final form adds another 140 stats on top.
How to Evolve
Best Build
Gen 1 build content has limited support (no abilities, held items, or natures).
Try selecting a different game/generation filter, or check back later.
Without TMs, Nidorino's movepool is bare bones. With them, you get Normal and Fighting coverage and more on top of Poison Sting for STAB. The natural kit handles basics, but TMs are doing the real work.
Level-Up Moves
TM Moves
Egg Moves
Tutor Moves
Nidorino is available from mid-game routes onward at high spawn rates. 4 encounter spots give you plenty of options. Grab one early and it'll be ready to evolve or train by mid-game.
