Not to be confused with the Stall thread, which is about playstyles, this is a thread about all things wall! A wall is a Pokemon capable of taking many hits. To kick us off, I'll start by listing good physical, special, and mixed walls.
Physical Walls:
To be a good OU physical wall, you need:
OU
Skarmory is OU's premier physical wall, for obvious reasons. He has base 140 Defense, which is the opposite of laughable. He can Spike and Phaze better than any other physical wall in OU and has reliable recovery in the form of Roost. He is immune to Ground and resists Dragon, with a neutrality to Fighting and Rock. Not much else comes close.
Nothing controls the hazard game quite like Forretress. With Rapid Spin, all three hazards, Sturdy, decent attack and a quick getaway in Volt Switch, Forretress is a mixed bag of utility. He also sports a resistance to Dragon, always nice, and only one weakness.
Gliscor sort of fell into disfavor after the Banning of Excadrill, but it's still far from useless. Poison Heal gives him immunity to status and good recovery. He also sports the great Ground attacking type and resistances to Ground and Fighting. Unfortunately, his DW ability makes his best moves illegal, most notably Stealth Rock and Roost.
UU
Slowbro is another good wall, capable of stopping what Skarmory can't: namely, Terrakion and Conkeldurr. Slack Off and Regenerator give him intense staying power and Scald's 30% burn chance means that you have a chance to cripple physical attackers even after Slowbro dies. If you see him, might as well chill out and drink a natty ice because he ain't going anywhere.
Tyranitar is getting all the love when it comes to Sand, but Hippowdon is no joke either. He is able to counter physical dragons, as although he does not resist, he has insane 108/118/72 Defenses and Slack off. Great ground STAB as well, Ice Fang, Stealth Rock, Yawn, and Whirlwind mean you underestimate the other Streamer at your own risk.
RU
Special Walls:
Special walls should:
OU
Blissey - ticking off special attackers since Gen II. Nothing says Special Wall as iconically as this pink blob. Insane base 255 HP and 135 SpD means she can tank literally anything special. Access to Wish, Softboiled, Aromatherapy, Toxic, Thunder Wave, and Stealth Rock means that she can do more than just sit there pretty while she's out, as well.
Tentacruel is one of those classics everybody loves. Rapid Spin and Toxic Spikes, base 120 SpDef and insane speed for a wall are just some of the perks he has to offer, as well as a great typing, both defensive and offensive. He resists both Ice and Fire. Sadly, he has no reliable recovery, but Rain Dish + Leftovers in Rain gives him Gliscor-level recovery.
Jellicent has great special defense and HP and a great typing as well. With access to Will-O-Wisp, he can pseudo-boost his own Defense to boot. Three immunities to Fighting, Normal, and Water, and resistances to Fire and Ice are no joke either. Don't underestimate this jellyfish.
Gastrodon can more or less walk straight over rain teams with the Ability Storm Drain and his great special defenses of 111/82 and only one weakness. He can either go the defensive route with Recover, Toxic, and Scald or power through with Specs after a Storm Drain boost. Rain teams, make sure you pack a counter.
UU
Mixed Walls:
A mixed wall should:
OU
After a long stint at the top of the leaderboard, Ferrothorn has started to decline in usage but is hardly less effective. With access to Spikes, SR, and Leech seed (but not all at once, sadly) he can support his team well and heal himself fairly well to boot. A crippling 4x weakness to Fire hurts, though.
Jirachi has two main purposes in life: Iron Head Flinch and a great mixed wall. With Steel typing allowing it to tank Draco Meteors like a boss and the ability to hit physical or special makes him a force to be reckoned with.
UU
Porygon2 has kind of lost its glamor since the beginning of the fifth Generation, but it's still a beast with Eviolite equipped. It can counter many Pokemon with Trace, such as Heatran, Chandelure, Jellicent, and Jolteon. Very few things that are not Fighting Type can bust through it, so Pory can either Recover stall endlessly and hit with surprisingly high power, or Thunder Wave and switch to a counter.
RU
One word: Unaware. Quagsire is able to stall out all boosters with his gift of an ability. Recover, Stockpile, Curse, blahblahblah.

Physical Walls:
To be a good OU physical wall, you need:
- Good HP and Defense (Obviously)
- Reliable Recovery
- Resistance to some of Dragon, Fighting, Ground, or Rock
- The ability to set up hazards and/or phaze reliably (not mandatory)

karpman said:Tangrowth is certainly a wall worthy of mention, and arguably the best in the OU Tier. With a Base 100 HP Stat and a Base 125 Defense stat, its Physical Bulk is unrivaled for the most part. With Regenerator, this thing can literally take a Close Combat from Terrakion, threaten it with the impending Giga Drain/Power Whip and then switch back out and regain the majority of its lost health. With its great capacity to wall Physical Threats, Tangrowth is a great abuser of Regenerator and can wall multiple threats in a game with ease. In addition to this, Tangrowth has an Attack Stat of 100 and a Special Attack Stat of 110, with Hidden Power Ice, Giga Drain and Earthquake, Tangrowth can hit the majority of Physical Threats for Super Effective Damage that ends up taking out a large chunk of their health, while also pressuring their sweep via Leech Seed or halting it completely with Sleep Powder.
Special Walls:
Special walls should:
- Have high HP and Special Defense
- Have reliable Recovery
- Resist the types Ice, Fire, Electric, and Dragon
- Be able to support their team with status, wishes, or heal bell, among other things

Karpman said:Latias is an example of a really good special wall in the current metagame. It's typing is almost perfect for tanking special attacks, it gets reliable recovery in Roost/Recover, as well as a great Base 130 Special Defense Stat. The icing on the cake is Latias's ability to crush all Calm Mind or Nasty Plot sweepers with the tandem of Calm Mind and Roar. Instead of simply getting into a CM War with your opponent until someone gets a crit, Latias can keep all of its boosts and potentially sweep, while your opponent is forced to switch and loses all their boosts, therefore allowing it to be a surefire counter to the majority of Special Set-Up Sweepers.

mc fatigue said:A set I like to use if I have a physical wall on the team like Gliscor and Tangrowth. Scald does what it does, Haze trolls Volcarona and friends and of course Baton Pass, it can Toxic-stall with its great defenses and Recover recovers. Also doesn't mind getting burned or paralysed due to Marvel Scale.
Of course you can go all-out physical defense with 252HP/252Def Bold or special defense 252HP/252SpDef Calm which lets it reach 383 special defense.
Another cool set is the RestTalk set with Scald and Dragon Tail. Rest activates Marvel Scale which boosts physical defense by 50%, so good luck taking Milotic down now. Dragon Tail is there to phaze and stop set-up sweepers, but with it's bad Attack stat you can easily sub up on it.
Mixed Walls:
A mixed wall should:
- Be generally pretty cool
- Live long and prosper

jimera 0 said:Oh cmon, you lot know it was coming. With Hydration and rest, bold nature, max defense and HP, Vaporeon is a spectacular mixed wall in the rain, and it can also hit back quite hard with a rain boosted Scald. Additionally, immunity to status means it can beat out other walls with toxic and burn while they are unable to harm it. Finally, when given Haze it is a hard counter to most stat boosters. It's only really beaten by pokemon with outrageously powerful attacks (CB Haxorus Outrage for example), or strong electric and grass type attacks (specs rotom-W, Jolteon, Celebi, etc).

alphatron said:Cresselia, for instance is something I like to use every now and then because she's the best counter to DD Multiscale dragonite. She also counters all types of terrakion (X-scissor doesn't 2hko), landorus, haxorus, and a multitude of offensive pokemon in general. Sure, she doesn't phaze or put up any hazards. She can't wishpass either. But she avoids becoming what other defensive walls usually end up being (a complete momentum killer for you, not your opponent) by being scared of very little. By running hp fire on my (what else?) sun team, cresselia is able to lure in the Scizor part of the Scizor/Rotom duo and pick him off without any prediction. She also countered excadrill, and when blaziken was around she took care of him too (mixken lost, and drought was absolutely necessary for SD AdamantKen to stand any chance).
If you need the team support she has to offer, then lunar dance is the best you're going to get. Your sweeper is near death and won't be able to finish its job? Not a problem. After cresselia has done what she needed to do, you can have her use lunar dance to give you a fresh pokemon. This is even better now that lunar dance has been fixed to work correctly on PO (it activates before hazards are layed down.)
