[OVERVIEW]
Gyarados is one of the most powerful setup sweepers in UU due to its fantastic coverage and combination of Dragon Dance and Moxie, which allow it to muscle through almost everything in the tier. Great coverage moves like Ice Fang help it break through bulky foes like Amoonguss and Salamence, and Power Whip allows it to hit Slowking and beat standard Unaware walls like Quagsire and Pyukumuku, unlike many other physical sweepers like Azumarill. It has good HP and respectable bulk, allowing it to withstand attacks while setting up. Unfortunately, its only Flying-type STAB move is Bounce, which has low accuracy and is exploitable because it requires two turns to use without Power Herb. Unboosted Gyarados is outsped by many common threats such as Zeraora and Terrakion. Even at +1 Speed, it will still get outsped by Choice Scarf users like Krookodile, Victini, and Zarude. Gyarados struggles against defensive Pokemon like Skarmory and Celesteela, and it does not have coverage options to easily power through other foes with respectable bulk like Kyurem.

[SET COMMENTS]
Ice Fang hits Dragon- and Grass-types like Salamence, Kommo-o, and Tapu Bulu. However, Gyarados requires multiple boosts to reliably KO bulky Grass-types like Tangrowth and Amoonguss with it. Bounce can be used over Ice Fang, as it provides an additional STAB move and can more reliably KO a chipped Amoonguss with just one boost. While Bounce can be used without Power Herb on both hyper offensive and balanced teams, not running Power Herb makes Bounce easy to exploit with Protect, Substitute, or switching, and Power Herb can only feasibly be used on hyper offense. Power Whip offers essential coverage against bulky Water-types like Slowking and Rotom-W. It also allows Gyarados to break through the Unaware Pokemon Quagsire and Pyukumuku. Moxie is the preferred ability, as it enables Gyarados to snowball through a team after one or two boosts. Intimidate can be used on a more balance-oriented team to set up more freely against physical foes, but it notably lessens Gyarados's sweeping potential. Heavy-Duty Boots is required to prevent Stealth Rock damage, allowing Gyarados to switch in more frequently. On a hyper offense team, Stealth Rock damage is not as big of a concern, so you can use Power Herb to get an immediate hit with Bounce. Lum Berry can also be used to freely set up twice against foes like Amoonguss and Chansey. An Adamant nature can be used for additional wallbreaking power, as it guarantees OHKOing Azumarill with unboosted Power Whip as well as Thundurus with +1 Ice Fang. However, Jolly is the preferred nature to outspeed Pokemon like Mamoswine, Chandelure, and Tapu Bulu unboosted and Jolly Zeraora after Dragon Dance.
Gyarados is best used on hyper offense teams, which have support options like dual screens to allow Gyarados to set up more easily. It can also be used on bulky offense teams due to the offensive pressure it offers, but these teams make it a bit harder to directly support. Gyarados has decent bulk to set up with Dragon Dance, which can be further bolstered with a screen setter like Alolan Ninetales or Grimmsnarl. Gyarados is primarily used as a late-game cleaner, but it struggles against defensive Pokemon like Chansey and Tangrowth. A teammate that offers entry hazard support helps wear these foes down enough for Gyarados to break through them. Mew can set Spikes, while Jirachi can set up Stealth Rock and offers Healing Wish support for Gyarados if needed. Terrakion is a great offensive partner that can also set up Stealth Rock and pressure foes like Chansey. Skarmory gives Gyarados a very hard time, as it can take multiple boosted hits from it and use Whirlwind. Having Magnezone to trap and remove Skarmory allows Gyarados to sweep more easily. Victini can also help against Skarmory, Chansey, and Tangrowth by hitting them for big damage with V-Create. Diggersby forces a lot of damage onto Celesteela, Skarmory, and Chansey, allowing Gyarados to clean these typically bulky threats up more easily. Gyarados will need teammates like Zeraora and Rhyperior to absorb Electric-type attacks. Krookodile offers an Electric immunity and can set up Stealth Rock. Gyarados is also in danger of being revenge killed by priority users, especially Lycanroc-D, so Rhyperior and Krookodile can help check these foes as well. Bulky Grass-types like Tangrowth and Amoonguss can reliably pivot into Zeraora while also offering Knock Off or Spore support. Gyarados can easily set up on foes that cannot heavily damage it, like Keldeo, so having a pivot such as Scizor and Victini can help bring Gyarados into play more safely and allow it to set up on these favorable matchups.
[STRATEGY COMMENTS]
Other Options
=============
A Substitute set with Waterfall, Bounce, and Leftovers as an item can help Gyarados break through defensive teams, as Substitute blocks status and Gyarados can easily boost multiple times against foes like Celesteela. However, the lack of coverage causes it to struggle with foes like Rotom-W and Quagsire. Earthquake is a coverage option to OHKO Electric-types like Magnezone and Zeraora as well as KO Tentacruel and Jirachi. However, Earthquake is generally not needed for Gyarados to power through most matchups, and dropping Power Whip will leave Gyarados without a tool to damage bulky Water-types.
Checks and Counters
===================
**Electric-types**: Electric-types like Zeraora, Thundurus, and Rotom-W reliably outspeed and KO Gyarados. While they can also withstand an unboosted hit, Rotom-W loses to boosted Power Whip, while Zeraora and Thundurus cannot consistently tank multiple hits. Magnezone is slower than Gyarados, but Gyarados will be unable to KO it without Earthquake or multiple boosts, and Magnezone will OHKO it back.
**Physical Walls**: Walls can be challenging for Gyarados, as it requires multiple boosts to KO them. Skarmory can safely switch in on Gyarados and use Whirlwind to remove its boosts. Celesteela can also withstand Waterfall after several boosts. Rocky Helmet Tangrowth can give Gyarados problems if it does not have Bounce, as +1 Ice Fang does not 2HKO. Chansey can also withstand several boosted hits and cripple Gyarados with Toxic and Thunder Wave.
**Choice Scarf Users**: Gyarados is slow, and many Choice Scarf users like Victini, Krookodile, and Zarude will outspeed it at +1 and deal heavy damage with STAB or coverage moves. Choice Scarf Rotom-W also outspeeds Gyarados at +1 and threatens to OHKO it with Volt Switch. Gyarados needs to boost to +2 Speed to overcome these threats.
