Sealeo sits in the middle of its evolution line — stronger than Spheal but not yet at full power. Most trainers push through to Walrein as fast as possible. Known as the Ball Roll Pokemon. Flexible enough to run physical or special sets.
Bulk defines Sealeo's stat line. HP and Sp. Atk anchor the defensive side, but Speed can't keep up offensively. Common in the wild and worth 2 HP EVs.
Its white whiskers are very sensitive. Sealeo will balance Spheal on the tip of its nose, checking its scent and its feel to be sure the Spheal is healthy.
Sealeo Weakness
VulnerableSealeo is weak to Electric, Grass, Fighting, and Rock-type moves. Thick Fat reduces Fire/Ice damage, further improving the defensive spread.
Partway through Spheal's chain. Sealeo still has another evolution ahead before reaching Walrein. For breeding, average hatch time with plenty of partners via two egg groups. HP has grown the most so far (+20), but there's still another 120 stats to gain in the final evolution.
How to Evolve
Sealeo hasn't fully evolved, but Eviolite's 50% bulk boost makes it viable anyway. Relaxed nature with Defense and Sp. Def investment EVs shapes the defensive spread, and Thickfat adds utility.

Legends: Arceus uses different battle mechanics.

A solid spread overall. Sealeo gets Blizzard and Ice Beam for same-type damage alongside Rock and Ground coverage and more. It won't blow anyone away, but it doesn't leave you stuck either.

Sealeo is meant to evolve into Walrein. At 410 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.
Thick Fat is what you want on Sealeo. Every competitive set worth running is built with that ability in mind. The alternatives (Ice Body, Oblivious) work on paper but Thick Fat is what makes Sealeo worth using.
Base 45 Speed is low. Priority moves or Trick Room are the way to go. On offense, Sealeo is a special attacker with base 75 Sp. Atk. Defensively? Enough bulk to take a hit or two.

Available in 15 titles since its debut in Ruby & Sapphire, Sealeo spans 7 generations of Pokemon games. It's accessible through catching or hatching as a base form in most mainline games.
