Blastoise Ultra Sun & Ultra Moon Guide
In Ultra Sun & Ultra Moon, Blastoise has a 530 base stat total and ranks as C-Tier: a niche pick in Ultra Sun & Ultra Moon's meta. It works best as a balanced. Rapid Spin with Leftovers is the standard set.
In Ultra Sun & Ultra Moon, yes. Mega Blastoise hits 630 BST, a solid jump from the base 530. Hold the Mega Stone, trigger it in battle, and it lasts the whole fight. One Mega per team.
Torrent strengthens water moves to inflict 1.5× damage at 1/3 max HP or less. That's the one you want on Blastoise. Rain Dish is the hidden ability. Niche, but it has its uses.
In Ultra Sun & Ultra Moon, Blastoise fills the balanced role. It's a mixed attacker with base 83 Attack and 85 Sp. Atk. Base 78 Speed is workable. Faster than some, slower than many. And it's tanky enough to absorb a few hits.
Game Availability
Blastoise first appeared in Red & Blue and spans 21 games across 10 generations. It later gained a Mega form in Generation 6 and a Gigantamax form in Generation 8, adding new dimensions to its competitive identity.
