Should you pick Mega Mewtwo X or Mega Mewtwo Y?
There are a few things that can impact your decision here: your Go Fest playtime, Mewtwo’s damage potential, and Mewtwo’s possible Adventure Effects. Notably, the Mewtwo you get from this Timed Research will have the first Mega Level already unlocked.
For one, Mega Mewtwo X is only available in raids on Saturday, July 11, whereas Mega Mewtwo Y is only available via raids on Sunday, July 12. For Mega Mewtwo X, you will need the similarly named Mewtwo Mega Energy X. On the flip side, for Mega Mewtwo Y, you’ll need Mewtwo Mega Energy Y. You can really only get these from raiding that type of Mewtwo and you need a tremendous amount of Mega Energy (7,500!) to Mega Evolve it the first time — and even more to power it up beyond that.
That being said, if you’re only going to be able to play on Saturday, you may want to pick the Mega Mewtwo Y — that way you can build up energy from raiding to get your own Mega Mewtwo X, and then get the “free” Mega Mewtwo Y from research (or vice versa).
If you’re looking for raw power, Mega Mewtwo Y is generally the stronger of the two, but only by a hair. Both of these are exceptional as psychic-type attackers, and the difference between them is near negligible. Both Mega Mewtwo types can be used as very strong attackers for other types, too, depending on its charged attack:
- Electric: Thunderbolt
- Ice: Ice Beam
- Fighting: Focus Blast
- Ghost: Shadow Ball
For these specialty types, Mega Mewtwo Y is stronger than Mega Mewtwo X, except for the fighting-type, where Mega Mewtwo X comes out on top, since it gains a fighting-typing. (Notably, Mega Lucario is stronger than Mega Mewtwo X as a fighting-type, so do with that what you will.)
So with all that out on the table, the answer is… it depends on when you’re planning on playing more and what you want, specifically. Both Mega Mewtwo are very powerful and worth having, but they have their own perks and strengths.
According to datamines, Mega Mewtwo was also supposed to have a unique Adventure Effect that you can activate to get a special bonus, but Scopely Explore hasn’t announced this formally, so we’re not sure if this idea has been completely scrapped or if it’s something coming after Go Fest (which would be weird). You can see the effects below, anyway:
- Mega Mewtwo X with Dynamic Punch: Allows you to break two shields in Super Mega Raids for 10 minutes.
- Mega Mewtwo Y with Future Sight: Reveals Pokémon with “high stats” before they are caught for 5 minutes.
Most players will find Mega Mewtwo Y’s Adventure Effect more useful, but if you play in a quieter area with fewer players, being able to break two shields can go a long way (especially if there are other people with this effect active). That being said, it’s possible that these Adventure Effects never see the light of day, so… (shrug)
