Is Seel Good in Red & Blue Playthrough?

Seel is slow and doesn't hit hard from either side. The evolution into Dewgong adds Ice typing, which gives it a specific role against Lance. Not worth using unless you specifically need that matchup covered.

Most of Seel's flexibility comes from TMs. Same-type output runs through Surf and Bubble Beam, but Normal and Ice and the rest of the TM pool push it from predictable to genuinely threatening.

Pokemon Red / Pokemon Blue

Seel Red & Blue Guide

  • Trade a Ponyta to the NPC on Cinnabar Island to receive Seel.. This is an NPC trade, so the Seel you receive is yours immediately, no transfer cable needed.

  • In Red & Blue, for a casual playthrough, Seel works as a placeholder. Water coverage is useful early. The real payoff is Dewgong. That's where the stats start mattering.

Game Availability

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