Mega Evolution in Pokemon GO is one of the most exciting features beyond just catching Pokemon. Not only does it dramatically boost your Pokemon’s combat power in battles, but it also gives your Pokemon a powerful and stylish new look.

In this guide, you’ll learn how to Mega Evolve in Pokemon GO, how to get Mega Energy efficiently, and which Mega-Evolved Pokemon are the best to train in 2025. I’ll also cover some frequently asked questions to help you get the most out of this feature. Let’s dive in!

What is Pokemon GO Mega Evolution?

Mega Evolution in Pokemon GO is a special temporary transformation that dramatically boosts a Pokemon’s stats and changes its appearance. First introduced in the mainline series, this evolution gives select Pokemon a significant advantage in battles, but only for a limited time.

When you Mega Evolve a Pokemon, its CP increases greatly, sometimes along with a type or ability change. While Mega Evolution is not permanent, it’s a powerful gameplay that can turn the tide of Raids, Gym Battles, and other in-game challenges.

What Are the Benefits of Mega Evolutions in Pokemon GO?

1 Greatly Boosts Battle Power

Massive CP Increase: Mega-Evolved Pokemon have significantly higher combat stats than their base forms.

Attack Bonus for All Pokemon: While a Mega Pokemon is in battle, all other Pokemon on your team get an attack bonus, making battles easier.

2 Useful in Multiple Battles

Raids & Gym Battles: Mega Pokemon boost your own and other Trainers’ attack power.

Team GO Rocket Battles: Mega Evolutions can help you quickly defeat Team Rocket Grunts and Leaders.

Friend Battles: You can use Mega Pokemon in friendly PvP battles and special events (except GO Battle League).

Aura Effects: Mega Pokemon appear with a special aura in raid lobbies, showcasing their power.

3 Extra Rewards and Bonuses

Bonus Candy & XP: While a Pokemon is Mega-Evolved, catching Pokemon of the same type gives extra Candy and XP.

Buddy Bonus: Set a Mega Pokemon as your Buddy to get CP boosts and faster heart accumulation.

4 Mega Evolution Pokedex Progress

Each Mega Evolution is tracked in a dedicated Pokedex tab. To access it, open your Pokedex and tap the Mega Evolution icon in the bottom right corner.

How Does Mega Evolution Work in Pokemon GO?

Now that you know the benefits of Mega Evolution in Pokemon GO, you're probably eager to try it out! Fortunately, the process of Mega Evolving a Pokemon is quite simple. Once you've gathered enough Mega Energy, just tap the “Mega Evolve” button to trigger the transformation. It's that easy!

But how do you collect Mega Energy? Below are the most effective methods:

Method 1 Earn Mega Energy from Mega Raids

The most common way to get Mega Energy in Pokemon GO is by defeating Mega Raid Bosses. These special Raid Pokemon are marked by a glowing Mega icon. The faster you defeat them, the more Mega Energy you'll receive - up to 90 Mega Energy per battle.

Time to Defeat	Mega Energy Earned
< 10 seconds	90 Mega Energy
11 - 30 seconds	80 Mega Energy
31 - 60 seconds	70 Mega Energy
61 - 90 seconds	60 Mega Energy
91 - 120 seconds	50 Mega Energy
> 121 seconds	40 Mega Energy

Important

Each Mega Raid only provides Mega Energy for that specific species. If you want to Mega Evolve Charizard, for example, you must defeat Mega Charizard raids.

Method 2 Complete Field Research for Mega Energy

Some PokeStops provide Field Research Tasks that reward Mega Energy. These missions often involve catching certain Pokemon, using Berries, or walking a certain distance. During special events, the amount of Mega Energy awarded may increase, so stay tuned to the in-game news.

Method 3 Get Mega Energy by Walking with Your Buddy

If a Pokemon has already Mega Evolved at least once, you can earn Mega Energy simply by walking with it as your Buddy Pokemon. You’ll gain 15 Mega Energy and 1 Candy for every 3 km you walk.

This method is ideal for long-term Mega Energy farming, especially for Pokemon you use often in Raids or Gyms.
