Mega Mewtwo Y and Mega Thunderus Y Dominate the PvE Tier List
According to PvE performance analysis from Niantic’s event breakdown, Mega Mewtwo Y stands as the undisputed king of Psychic-type raids. Running a moveset of Psycho Cut and Future Sight+, it melts Psychic-weak bosses faster than any other counter. Beyond Psychic, its diverse move coverage makes it a powerhouse for Fighting, Electric, and Ice damage, earning it a definitive S-tier rating and cementing it as a mandatory investment for dedicated raiders.
Sharing the S-tier spotlight is Mega Thunderus Y.
Pro Tip: Stick to Mega Mewtwo Y and Mega Thunderus Y if your primary goal is pure raid damage. Specialized attackers like Mega Aerodactyl and Mega Dragonite also offer incredible utility for general PvE content, according to event guides.
Reliable A-Tier Raiding Options for Trainers
For trainers seeking consistent, versatile typing without relying solely on Mewtwo, the A-tier offers standout choices. Mega Aerodactyl utilizes Rock Throw and Rock Slide to rank among the top Rock-type outputs, according to battle evaluations. While Mega Tyranitar and Mega Diancie boast higher stats, Mega Aerodactyl remains exceptionally cost-effective, easy to acquire, and immune to Ground-type attacks.
Similarly, Mega Dragonite breaks into the top tier of Dragon attackers. Armed with Dragon Tail and Outrage+, it sits just behind Mega Rayquaza, outperforming Mega Salamence in current output calculations. Though its Flying-type moves lag behind dedicated fliers, its balanced stats make it a reliable secondary option for dragon-weak bosses.
B-Tier and C-Tier Mega Evolutions: Who to Skip
Not every mega evolution makes the cut for competitive raiding.
Meanwhile, C-tier entries like Mega Sableye, Mega Mawile, and Mega Audino fail to impress in raids. Their offensive stats are simply too low to justify resource investment. Trainers are advised to save their Mega Energy and focus their candy on high-DPS choices during the GO Fest weekend.
Unlocking Rewards Through the GO Pass: Mega Finale
Alongside the raid schedule, Niantic introduced the free “GO Pass” feature for the event, according to official posts on pokemongo.com. Starting August 31, trainers can select a partner Pokémon from the Kalos region—Chespin, Fennekin, or Froakie—and complete tasks in mega raids to earn GO Points. Leveling up the pass unlocks Link Energy, candies, and enough Mega Energy to evolve the chosen starter at least once.
Players who opt for the paid “GO Pass Deluxe: Mega Finale” unlock additional perks, including boosted shiny encounter rates for event bosses, extra candy and XL candy from raids, exclusive avatar items themed after Kalos starters, and extra Mega Energy for their chosen partner Pokémon, per Niantic’s patch notes.
