Is Nidoran♂ (male) Good in Red & Blue Playthrough?

The offensive counterpart to Nidoran-F. Evolves at level 16 into Nidorino, Moon Stone immediately, and Nidoking carries you through most of the game. The male version trades some bulk for more hitting power.

Nidoran♂ (male) Red & Blue Guide

  • How do I catch Nidoran♂ (male) in the Red & Blue Safari Zone?

    See the Locations section above for where to find Nidoran♂ (male) in Red & Blue.

    Safari rules: You can only use Safari Balls. No battling. Two tactical items shift the catch/flee trade-off:

    • Throw bait to keep Nidoran♂ (male) from fleeing (flee rate cut to 1/4) but it becomes harder to catch (catch factor halved).
    • Throw a rock to make Nidoran♂ (male) easier to catch (catch factor doubled) but it flees twice as often.
    • Each effect lasts 2-6 random turns; throwing one cancels the other.
  • In Red & Blue, Nidoran♂ (male) has 273 BST, so weigh it against what your team already covers.

Game Availability

Present since Red & Blue, Nidoran♂ (male) appears in 19 games spanning 9 generations. Gen 1 originals like Nidoran♂ (male) have the longest track record of availability in the series.
