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 shatters ice with its big tusks. Its thick blubber repels not only the cold but also enemy attacks.
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.
The three-stage chain from Spheal through Sealeo ends here at Walrein. Want more? Breed for Spheal eggs. No compatible partners 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 from the Ground and Water1 egg groups. Notable egg moves include Aqua Ring, Belly Drum, Curse and 6 more.
Start with max HP and Sp. Atk EVs. Quiet nature gives Walrein the right slow special lean, Adrenalineorb adds extra utility, and Icebody works in the background. Blizzard is the main damage option.

Without breeding, Walrein misses out on Aqua Ring and Belly Drum. That's 9 egg moves adding depth that the base kit lacks. STAB comes from Blizzard and Surf, with Dark and Rock coverage and more rounding things out.
