Stats & Training
Blastoise's spread isn't flashy. Sp. Def leads, Speed trails, 4 stats clear the bar. Tough to catch and worth 3 Sp. Def EVs, on a 1.06M XP medium-slow curve.
It crushes its foe under its heavy body to cause fainting. In a pinch, it will withdraw inside its shell.
The pressurized water jets on this brutal POKéMON’s shell are used for high-speed tackles.
Blastoise Weakness
Electric and Grass moves hit Blastoise for super-effective damage. It resists 4 types, giving it decent defensive coverage. Blastoise's overall bulk (79/100/105) lets it take a hit or two from most weaknesses before going down.

|---|---|
| 2x (Weak) | Electric, Grass |
| 0.5x (Resist) | Fire, Water, Ice, Steel |
- Dark and Steel types added — Fairy does not exist yet

Moves
Don't skip the egg moves. Blastoise picks up Flail and Foresight only through breeding, and both fill gaps the natural movepool can't. STAB runs through Hydro Cannon and Hydro Pump while coverage across 7 types adds range.

Blastoise Guide
In FireRed & LeafGreen, Blastoise has a 530 base stat total and ranks as C-Tier: a niche pick in FireRed & LeafGreen's meta. It works best as a balanced. Surf with Leftovers is the standard set.
Mega Evolution isn't available in FireRed & LeafGreen, but Blastoise does have a Mega form in Gen 6-7 games (X/Y, ORAS, Sun/Moon). Mega Blastoise hits 630 BST.
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 FireRed & LeafGreen, Blastoise fills the balanced role. It's a special attacker with base 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 7 and a Gigantamax form in Generation 8, adding new dimensions to its competitive identity.
