Overview

Mega Gyarados may have fallen through the cracks to a certain degree in terms of viability when compared to its competition, but it's still going to make you feel pain when trying to farm down its Mega Energy! Mega Gyarados has the highest defense stat among all of the Water Type Mega Evolutions, and while it has the second highest defense of all Dark Type Mega Evolutions, it has no double weakness to exploit. This fact, when combined with a high attack stat and a few attacks that are just downright mean to face on a raid boss, makes Mega Gyarados a fairly challenging prospect! When aiming for the trio, TDO is going to be the main problem. Many of Mega Gyarados' attacks are not resisted by its counters, meaning it can wipe teams fairly quickly. But by prioritizing dodging, staggering team wipes so that it can't recover HP from a full-wipe, and throwing in an anchor or two to stay in the fight for as long as possible, it's definitely doable with 3 trainers. 

Note that a 2-person run is possible given Weather, Mega, and/or Friendship boosts, but it is more difficult.

Approach

Team composition

  • Front-load DPS options

  • The best teams for the short-man run strive for a mix of DPS and TDO.

  • Weather, Mega, and/or Friendship boosts can make a huge difference in total performance, and teams should be built around them.

  • Mega Venusaur is the best overall Mega Evolution, and should be prioritized for most players.

  • Try to stagger Mega Evolutions between all players so that the resulting boosts stay active for as long as possible.

Battling strategy

  • Re-entering will be necessary in the trio without boosts. Immaculate dodging may be able to avoid this.

  • Dodging is genuinely recommended.

  • It might be wise to have one player back out, heal up, and then quickly re-enter after their 3rd Pokemon faints. This will help prevent an all-trainer wipe that will allow Mega Gyarados to recover HP.

Note: "Good" movesets are not necessarily viable at the level indicated.
