1 Power Plant – Far southeast corner inside the building No

You will find TM25 Thunder in the far southeast corner of the Power Plant. You’ll be able to reach the Power Plant by surfing south on the river on Route 10 (you’ll need to surf just past the Rock Tunnel entrance).

So before you can get this TM you’ll need Pokémon that can use HM01 Cut and HM03 Surf.

Cut is needed to reach Route 9 & Route 10, while Surf is necessary to cross the water leading to the Plant.

Type Electric
Category Special
Power 120
Accuracy 70
PP 10

If it weren’t for Thunder’s poor Accuracy of 70%, it’d be hard to argue against it as the most powerful move in FireRed & LeafGreen.

The attack has a dominating base Power of 120, and a whopping 30% chance of paralyzing its target.

This move’s accuracy is really its Achilles heel.

Although there is a way to fix Thunder’s poor Accuracy.

When you use Thunder in rainy conditions, the attack’s Accuracy is boosted to 100%.

So it would be ideal to pair both Rain Dance and Thunder together in a Pokémon’s moveset. That way rainy conditions could be created easily and help you consistently land each Thunder attack.

There are a few Pokémon that can be taught both Thunder and Rain Dance in FRLG. Some of the better options include Starmie, Gyarados, Lapras, and Dragonite.

As a Special move, Thunder’s potential Power is largely dependent on the user’s Special Attack stat. So if you’re looking to get the best bang for your buck, teach TM25 to a Pokémon like Magneton.

Other Electric-types in FireRed & LeafGreen with great Special Attack stats can just learn Thunder via level-up, such as Jolteon, Zapdos, and Ampharos.
