Is Blastoise Good in Let's Go Pikachu & Eevee Playthrough?

Blastoise handles Blaine, Giovanni, and most of Lance's team without breaking a sweat. Your partner often outpaces it in coverage, but Blastoise brings Water-type consistency that stays useful from the moment you get it through the Champion fight. After Badge 7, Blue gives you the Blastoisinite, and Mega Blastoise turns it into a cannon for Giovanni and the Elite Four.

How to Get Shiny Blastoise in Let's Go Pikachu & Eevee

In Let's Go Pikachu & Eevee, the strongest route to a Shiny Blastoise is Catch Combo, which reaches about 1 in 274 at full boosts. Shininess carries through evolution, so hunting an earlier stage and evolving it counts too. Pick a method and tune your setup below to see live odds. Compare Shiny Blastoise odds across every game

Fastest Path

The best route is Catch Combo at full boosts, about 1 in 274 on each try. Tune it below.

Step 1 · Encounter Method2 in Let's Go Pikachu & Eevee

Catch Combo: Catch one species back-to-back. A Lure stacks on top of a 31-plus combo.

Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.

How is this calculated?

Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.

chance after N tries = 1 − (1 − p)^N,  where  p = 1 / odds per try

Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.

The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.

These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.

Let's Go Blastoise Best Moveset

Mega Blastoise reaches 135 Sp. Atk, putting real power behind MoveHydro Pump, MoveIce Beam and MoveDark Pulse. Let's Go has no abilities, so Mega Launcher never boosts pulse moves; the gain is pure stats. Without the Mega, 85 Sp. Atk at 100/105 defenses is too passive. The Mega transforms everything.

Sassy raises Sp. Def and lowers Speed. Madam Celadon sets this nature when you pick Green, then Pink. It costs 10,000 Pokedollars and lasts for the rest of the day.

Candy for Blastoise

Squirtle Candy raises every stat, but only Squirtle, Wartortle and Blastoise can eat it. The stat candy that goes with Blastoise is Courage Candy (Sp. Def), and any Pokemon can eat it; Courage Candy L needs level 30 and Courage Candy XL needs level 60 or higher.

Mega Evolution

  • Mega Blastoise630 BST
Mega Blastoise 3D model in Pokemon Let's Go Pikachu and Eevee
Mega Blastoise

Mega Blastoise (Water type) has 79 HP, 103 Attack, 120 Defense, 135 Sp. Atk, 115 Sp. Def and 78 Speed, 630 in total. Weak to Electric and Grass. Resists Fire, Water, Ice and Steel. Best nature for Mega Blastoise: Quiet (Madam Celadon: Blue, then Pink). Mega Stone: Blastoisinite, a gift from Blue in Professor Oak's Lab in Pallet Town after your seventh Badge. Pokedex: The cannon on its back is as powerful as a tank gun. Its tough legs and back enable it to withstand the recoil from firing the cannon.

Mega Evolution can be used once per battle, on one Pokemon.

Master Trainer

Tessa battles with one level 80 Blastoise that knows Fake Out, Rock Slide, Dark Pulse and Substitute. It takes extra damage from Electric and Grass moves. Win to earn the Blastoise Master title. Find Tessa on Route 20.

Moves List

Blastoise develops a solid moveset just through leveling. Hydro Pump and Skull Bash show up naturally, and the progression handles both STAB and utility without leaning on TMs for the core attacks.
