You can catch Nidoran Male in the small square of grass to the left of ViridianCity (on the path to Victory Road and the Elite 4). While Onix is using bide, send out charmander and use growl. Then once it dies, bring in Nidoran (or Nidorino) and use horn attack. Thanks for watching and subscribe for more!! Like if you enjoyed :)
