Seel is a pure Water type that evolves into Dewgong at level 34. It shares its Sea Lion Pokémon category with Dewgong and Popplio. It makes its home on icebergs, copes with water as cold as minus 40 degrees, and grows livelier as the temperature falls. Seel is likely based on an earless seal, drawing further inspiration from belugas, narwhals, and walruses for its long white body, horn, and tusks.
Seel is the only non-Ice-type Pokémon that can have the Ability Ice Body, making it the only such Pokémon that actually benefits from Ice Body's hail immunity, since every other Pokémon with the Ability is already naturally immune to hail damage due to its typing.
Seel's first card appeared in the 1999 Base Set as an Uncommon illustrated by Ken Sugimori. Gym Heroes and Gym Challenge each added a Misty's Seel card the following year. Dragon Frontiers printed a δ Seel illustrated by Hajime Kusajima, and the Mega Evolution era's Phantasmal Flames and Perfect Order each added a Seel Common.

The leaders among the most valuable Seel cards come mostly from the WOTC era, with eight of the ten leading cards printed there, and the top spot belongs to a Common from Skyridge in 2003. All 20 of the 20 Seel cards carry a market value, and the ten leading cards hold 97 percent of the total, so Seel card value rests on a narrow group of prints. The priced cards span 1999 to 2026.
The most valuable Seel card is the Skyridge Common from 2003, ahead of the next card by 1.7 times, and that runner-up is a second Skyridge Common from the same year. Third comes the Seel Uncommon from Base Set in 1999. Fourth and fifth are Misty's Seel, a Common from Gym Challenge and a Common from Gym Heroes, both printed in 2000. Every one of these Seel cards is a Common or an Uncommon.
Eight of the twenty-five leading Seel cards come from WOTC, two each from EX, Diamond & Pearl, XY, Sword & Shield and Mega Evolution, and one each from Sun & Moon and Scarlet & Violet. Vintage here means the WOTC era, and it holds 8 of the top ten against 2 modern cards, while the top twenty-five splits 8 vintage and 12 modern. The newest era's leader is the Mega Evolution Seel from Perfect Order in 2026, 16th overall.
Among the ten most valuable Seel cards, the printed rarities are 8 Commons and 2 Uncommons. Widening to the leading twenty-five, the count becomes 18 Commons and 2 Uncommons. Every one of the leading Seel cards, in both groups, is printed as a Common or an Uncommon, so the Seel card value ranking is made up of those two printed rarities from first place to twenty-fifth.
By the value of its single leading card, Seel ranks 353rd of 1020 species with priced cards, and by the combined value of its ten leaders it ranks 371st of 753. Its evolution line adds Dewgong, whose top card ranks 80th of 1020. Seel's card market is built on a few older Commons, with Dewgong's best card placed well above Seel's own.
