Pokémon GO Fest 2026: Mega Mewtwo Timed Research Guide

The Mega Mewtwo Timed Research Guide is officially here and trainers have a massive decision to make. The Pokémon GO Fest 2026 features this branching Timed Research alongside the Zeraora Special Research. Players can tackle a branching Timed Research line called Genetic Mastery. Completing these tasks unlocks the ultimate power: Mega Mewtwo X or Mega Mewtwo Y.

Unlike the Zeraora Special Research, this is Timed Research, which, you must complete all the tasks and claim your rewards before the GO Fest weekend event expires.

The event runs strictly from 10:00 a.m. to 7:00 p.m. local time on both Saturday and Sunday. If you fail to complete the Genetic Mastery steps and claim your rewards before 7:00 p.m. on Sunday, the entire questline will vanish from your “Today” view, and you will lose out on the exclusive Mega Energy.

Here is the full breakdown of the opening steps and how to choose your path.

Be Ready for Super Mega Raid Battles

To maximize your Genetic Mastery rewards, you need to defeat Mega Mewtwo in the Super Mega Raid Battles. These battles are highly challenging, so make sure to bring top-tier counters:

• Mega Mewtwo X Counters (Psychic/Fighting): Vulnerable to Flying, Ghost, and Fairy-type attacks. Rely heavily on Mega Rayquaza, Dawn Wings Necrozma, Mega Gardevoir, or Mega Gengar.
• Mega Mewtwo Y Counters (Psychic):** Vulnerable to Bug, Ghost, and Dark-type attacks. Utilize Mega Tyranitar, Dawn Wings Necrozma, or Mega Gengar.

Pro-Tip: Make sure to coordinate with large groups and keep a Mega-Evolved Pokémon in your lineup to boost your team’s attack damage throughout the raid!

Tips for Completing the “Mega Mewtwo Timed Research Guide” Quickly

1. Stack Your Field Research: While catching 20 different species, make sure you spin every PokéStop to restock your Poké Balls and gather easy event tasks.

2. Pre-Walk Your Eggs: Keep 2km Eggs handy for Step 3 so you can pop them into Incubators and hatch them quickly.

3. Save Your Mega Energy: Keep a low-cost Pokémon (like Beedrill or Pidgeot) ready to Mega Evolve for Step 3 so you don’t burn rare resources early on.

4. Tag Power-Up Targets Ahead of Time: Step 2 requires you to power up a Pokémon 10 times. Avoid scrolling through your storage mid-event by tagging low-Stardust Pokémon (like lucky or low-level catches) in advance so you can clear the task instantly.

Have fun completing the Mega Mewtwo Timed Research
