Registeel's bulk means that it can easily wall and check many specially offensive Pokemon in the tier like Comfey, Swellow, Diancie, Roserade, and Dragalge while serving as a blanket check to many Pokemon that can only hit it neutrally, especially with special attacks. This, in tandem with access to helpful utility moves such as Stealth Rock, also allows it to be a very consistent setter, finding many opportunities to set up. Registeel
Itcan also cripple opposing Pokemon with status without ever being overly passive, as it can stall with Protect and Toxic and deal solid damage with Seismic Toss. On the other hand, its typing means that it is weak to the ever-common Ground-, Fire-, and Fighting-types, specifically being pressured by Salazzle, Flygon, Zygarde-10%, and Pangoro with their super effective STAB moves and common coverage moves such as Focus Blast and Earthquake. In addition, it is susceptible to Taunt, which, as a consequence, makes it susceptible to common users of the move like Chesnaught and Mismagius. (is just "susceptible to Taunt users like Chesnaught and Mismagius" the same thing? less wordy)
name: Specially Defensive
move 1: Seismic Toss
ToxicProtect (match with the order you talk about them in the Moves section)
ability: Clear Body
evs: 252 HP / 4 Def / 252 SpD
Seismic Toss does a solid 100 HP of damage to anything that isn't a Ghost-type, allowing Registeel
itto dish out decent damage or break Substitutes of Pokemon that may try to set up on it. Toxic is used in tandem with Seismic Toss to whittle down the array of bulky Pokemon in the tier such as Porygon2, Slowbro, and Umbreon. Stealth Rock is mandatory to pressure Pokemon switching in while breaking Focus Sash and Sturdy, making it so that teammates have an easier time cleaning up late-game. Protect has a multitude of uses, such as stalling out extra damage from Toxic and recovery from Leftovers, scouting for Choice items, and cushioning Z-Moves that may otherwise outright KO Registeel it.
Running 252 EVs in HP and Special Defense along with a Calm nature maximizes Registeel's special bulk, but if Iron Head is being used (if it's worth mentioning here then it's worth mentioning in the Moves section. if it's not worth mentioning in Moves then it also shouldn't be here. either move the Iron Head sentence in Other Options to the end of Moves or remove the two Iron Head mentions here and instead mention using a Careful nature in the Iron Head sentence in Other Options), a Careful nature should be run instead. Leftovers is used to mitigate Registeel's
itslack of recovery and help it stay out for longer on the field. Clear Body is chosen to avoid stray stat drops from moves such as Shadow Ball and Psychic , (remove comma)and, if using Iron Head, the Attack drop from Intimidate.
Stealth Rock should be set up as early as possible to start racking up chip damage, heavily damaging Fire-, Bug-, and Flying-type Pokemon such as Moltres, Salazzle, and Yanmega, limiting their use in play. Switch Registeel into foes that cannot do much to it, such as Dragalge, Jolteon, Cresselia, and Diancie, in order to force them out, allowing it to get Stealth Rock up or take advantage of status
, though. However, be wary of super effective coverage moves such as Focus Blast from Hoopa and Zoroark, as, despite Registeel's special bulk, it will still take a measurable chunk of damage from them. While it can take neutral physical hits fairly well, do not switch Registeel into them too often, as lack of Defense investment along with no recovery outside of Leftovers means it will get worn down fairly fast. Make use of Protect to stall out turns of Toxic damage along with PP and to heal with Leftovers while scouting for possible Choice items, but do not overuse it, as it may lead to free switches.
Cresselia, Gligar, and Golbat are all good checks to Fighting-types, with the latter two helping Registeel's longevity by removing hazards with Defog, while Cresselia can deal with Pokemon like Salazzle and Chesnaught slightly better. Chesnaught's natural physical bulk and resistance to Ground-type attacks
meansmean that it can take on the physical hits, such as Thousand Arrows from Zygarde-10%, that Registeel may not want to stay in on, and access to Taunt and Spikes means that it can keep Stealth Rock on the field while setting up more hazards alongside them. Umbreon supports Registeel by providing Wish and Heal Bell support, upping its longevity while serving as a check to Nidoqueen. Rotom-H's Levitate allows it to switch in on opposing Ground-type moves with no drawbacks, and, thanks to its Fire typing, it can take on other Pokemon that wall or threaten Registeel such as Doublade, Escavalier, and Mega Abomasnow. Rotom-H's access to Volt Switch further means that it can safely bring in Registeel on a predicted switch while damaging the foe, and Will-O-Wisp helps Registeel take on more of the physical attackers in the tier after they've been inflicted with a burn. Araquanid is a more offensive partner, but due to its resistances to all of Registeel's weaknesses and Water Bubble, it can come in on a wide variety of moves that threaten it and can often force their users themout or outright KO them, while Registeel supports it by taking the Flying-, Rock-, and special Electric-type moves that it fears.
Thunder Wave can be used to cripple faster threats like Moltres and Durant on the switch, but, as a consequence, Registeel
itbecomes more passive, as it loses out on the damage from Toxic, becoming unable to do anything to a status afflicted Ghost-type. Curse can be used with the same EV spread with a Careful nature, allowing it to take physical hits better and deal more damage with Iron Head, if running it. Iron Head can be used over Seismic Toss to hit certain Pokemon that may completely wall Registeel otherwise itsuch as Froslass, which it 2HKOes with no investment. (add period) Rest and Sleep Talk can be used in order to somewhat mitigate the lack of reliable recovery, but it's usually not worth what you're giving up for it. Earthquake can be used to KO the Fire-types Registeel lures in such as Salazzle, which thatmay go about settingtry to set up Nasty Plot, expecting you to switch out.
Checks and Counters
**Ground-types**: Flygon, Rhyperior, and Zygarde-10% can all 2HKO Registeel with their Ground-type STAB moves or start setting up on a predicted switch out. Gligar is also immune to both Thunder Wave and Toxic by virtue of Immunity and can dent it quite a bit with Earthquake. Ground-type coverage such as Earthquake from Mega Abomasnow can also damage it sufficiently.
**Fire-types**: Salazzle, Moltres, and Rotom-H can all heavily damage Registeel with their powerful Fire-type STAB moves, and Ninetales can OHKO it using Inferno Overdrive boosted by Drought. However, Fire-types
don’tdon't like taking Stealth Rock damage, and the former two are crippled by Thunder Wave.
**Fighting types**: Kommo-o, Chesnaught, Bewear, and Pangoro can all heavily damage or cleanly OHKO Registeel with their respective STAB moves, depending on the Pokemon's set or chip damage, and can force it out very easily. None like Thunder Wave, but Chesnaught can shut it down with Taunt, and Pangoro may hold a Lum Berry.
**Status-Immune Pokemon**: Pokemon immune to Toxic
and/or Thunder Wave, such as Escavalier, Durant, and Doublade, have an easy time setting up on and proceeding to outright KO Registeel. Substitute users such as Hoopa are also unable to be inflicted with status and, in any Ghost-type's case, cannot have Substitute broken by Seismic Toss.
**Taunt**: Taunt users like Sableye, Mismagius, and Chesnaught can completely shut down Registeel, forcing it out or leaving it incapable of doing anything but using Seismic Toss.
