what type is nidoq
Fire Blast is the main choice in the second moveslot as it allows Nidoqueen to hit Steel-types who don't care about Earthquake, such as Skarmory and Forretress, for solid damage. However, Super Fang is a viable alternative, allowing Nidoqueen to immediately strip any switch-ins of half their health, bar Ghost-types. Stealth Rock is the main option in the fourth moveslot, as it allows Nidoqueen to further support her team; she can set it up in the same situations where she sets up Toxic Spikes.
