Between Thick Fat and Ice/Water typing, Walrein carves out a strong competitive niche. It halves incoming Fire and Ice damage, which gives it an edge most Pokemon in its stat range don't have. Can go either physical or special depending on the set.
Walrein's built to absorb hits, not race for knockouts. Balanced defenses with HP doing the heavy lifting. And the 1.06M XP medium-slow curve means it won't take forever to bring up, worth 3 HP EVs.
It swims through icy seas while shattering ice floes with its large tusks. It is protected by its thick blubber.
Walrein Weakness
VulnerableElectric, Grass, Fighting, and Rock-type moves hit Walrein for super-effective damage. Thick Fat reduces Fire/Ice damage, further improving the defensive spread. Walrein's overall bulk (110/90/90) lets it take a hit or two from most weaknesses before going down.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
The three-stage chain from Spheal through Sealeo ends here at Walrein. Want more? Breed for Spheal eggs. A massive partner pool available via two egg groups. The evolution from Spheal pushed Walrein to 530 total stats. HP saw the largest single gain at +40.
How to Evolve
Breed with Walrein to get Spheal eggs easily using 102 partners from the Ground and Water1 egg groups. Notable egg moves include Curse, Fissure, Rock Slide and 5 more.
Walrein doesn't rely on pure speed. Leftovers gives it passive recovery each turn to stay healthy, and Modest nature still pushes offense. Surf and utility options keep the pressure on while max HP and Sp. Atk EVs balance power and survivability.
