| 0.5x (Resist) | Fire, Water, Ice |
- 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

Seel Evolutions

How to Evolve
Y Seel Best Moveset
70 Special behind Water moves that can't compete with Lapras, Starmie, or any of the top Water-types even at full power. The Ice typing arrives with Dewgong, where the stats at least function. Nothing competitive happens before evolving.
Best Build
Utility Moveset
- Surf
- Body Slam
- Double Edge
- Bubble Beam
Moves List
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.

Seel Yellow Guide
In Yellow, 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.
