Because of Darkrai, Thundurus is a rather overlooked Uber despite its wonderful offensive stats and a high base 111 Speed. However, its immunities to Ground-type attacks, Spikes, Toxic Spikes, and access to the most powerful Thunder in the game after a Nasty Plot boost all differentiate it from Darkrai. Thundurus also gets the excellent Prankster ability, which endows it with a priority Thunder Wave and Taunt, allowing it to stop most entry hazard leads in their tracks. Choice Scarf users such as Palkia and Zekrom fear to revenge kill Thundurus since it can leave a parting gift in the form of Thunder Wave, crippling them for the rest of the match. Thundurus can also stop a sweeper such as +1 Dragon Dance Rayquaza (provided that it doesn't have ExtremeSpeed) in an emergency with Thunder Wave, although Thundurus will usually die in the process. Unfortunately, this genie has its share of weaknesses. Thundurus is incredibly frail, even more so than Darkrai, and it suffers from a crippling Stealth Rock weakness, which ensures that it will never last too long on the battlefield factoring in Life Orb recoil. Nevertheless, with the proper team support, Thundurus can be very difficult to stop, and is a threat which every team should watch out for.
Thundurus's impressive base 125 Special Attack and base 111 Speed make it a force to be reckoned with in Ubers, where its main niche is its devious Prankster ability that gives it priority to support moves such as Taunt and Thunder Wave. Taunt stops most common leads, including Deoxys-S, from setting up entry hazards. Thunder Wave can be used to cripple a Choice Scarf user such as Palkia or Shaymin-S and pave the way for a sweeper, while Volt Switch in conjunction with Thundurus's blazing Speed makes Thundurus a fine scout. STAB Thunder is the primary offensive option, and it does massive amounts of damage to anything that doesn't resist it, OHKOing all variants of Lugia and Kyogre with Stealth Rock support. Hidden Power Ice rounds off Thundurus's coverage nicely, 2HKOing Support Groudon and most Dragon-types packing an Ice-type weakness. Hammer Arm is possible in the last slot since it places a nice dent in most Pokemon that give Thundurus trouble. Blissey takes a nice 63.8% - 75.2% from a Life Orb boosted Hammer Arm, and the move scores a guaranteed 2HKO on Chansey after Stealth Rock damage. Hammer Arm also OHKOes Tyranitar and puts a nice dent into the likes of Dialga and Ferrothorn. A Naive nature should always be used instead of Timid so that Hammer Arm does maximum damage. A Hasty nature is not preferred since it leaves Thundurus prone to the more common physical priority moves from the likes of Arceus.

Thundurus has everything one could possibly need to run a Nasty Plot set effectively: blazing Speed, a sky-high Special Attack stat, and key immunities to Spikes, Toxic Spikes, and Ground-type moves. The basic idea is to switch in on a support Pokemon, such as Ferrothorn, or a Pokemon that Thundurus scares out, such as Kyogre, grab a Nasty Plot as they switch out, and gear up for a sweep. Nasty Plot pumps Thundurus's already impressive Special Attack stat to an amazing 698, making it a terror to face. Thunder will do insane amounts of damage to anything not immune or resistant to it. Just to put it into perspective, Palkia is cleanly OHKOed by a +2 Thunder, while Reshiram, which is resistant to Electric-type moves, takes a massive 65.7% - 77.6%, an OHKO factoring in Stealth Rock and a layer of Spikes. Any Groudon foolish enough to switch into Thunder is swiftly taken down with Hidden Power Ice. Focus Blast dents Pokemon such as Dialga and Ferrothorn that can otherwise annoy Thundurus, rounding off Thundurus's overall coverage very well.

Agility can be used on Thundurus to further boost its Speed stat and help remedy its chronic problem with Choice Scarf users. However, after an Agility boost, Thundurus lacks the power to take down Mewtwo with Thunder without Spikes and Stealth Rock. Also, bulkier Choice Scarf users such as Zekrom, Dialga, and Palkia will still beat Thundurus regardless. Substitute can be useful on the Prankster set to scout for switches but will make Thundurus have an even shorter life span if you predict wrongly.
Checks and Counters
Anything faster than Thundurus will KO it pretty easily due to its frailty. Mewtwo, Darkrai, and Choice Scarf users such as Palkia and Dialga come to mind. Although they risk being crippled by Thunder Wave, Thundurus will usually die to them. Chansey can beat the Life Orb set easily even when Taunted. It takes a meager 18.2% - 21.5% from Thunder and can take out Thundurus with repeated Seismic Tosses. However, it still needs to watch out for the Nasty Plot set, since a +2 Focus Blast will 2HKO. Blissey falls in the same category as Chansey, except for the fact that it can actually 2HKO Thundurus with Ice Beam. Both the blobs will, however, hate taking a Hammer Arm to the face. Giratina, especially the specially defensive variant, is quite a good counter to Thundurus. It can stomach Hidden Power Ice easily and can phaze out Thundurus with Dragon Tail or paralyze it with Thunder Wave. Ground Arceus is one of the best counters to Thundurus since it is immune to Electric-type moves, survives a Hidden Power Ice or even Grass Knot, outspeeds Thundurus, and can easily 2HKO with Ice Beam or Stone Edge (OHKOes after Stealth Rock damage). Both Grass Arceus and Electric Arceus give Thundurus issues since they resist Thundurus's Electric STAB and laugh at Hidden Power Ice, which fails to 2HKO either of them. Neither of them likes Thunder Wave, however, though both usually run Ice Beam to KO Thundurus. Specially defensive Groudon can switch into Thunder, survive a boosted Hidden Power Ice, and KO with Stone Edge. With Stealth Rock off the field, Ho-Oh is only 2HKOed by Thunder and can deal massive amounts of damage with Sacred Fire. Pokemon packing priority moves in their arsenal, such Rayquaza, Arceus, and Lucario, can KO Thundurus if it has taken some previous damage. An ExtremeSpeed from Adamant Rayquaza does 62.2% - 73.2%, and will OHKO if Thundurus has taken some damage in addition to Stealth Rock.
