Monotype Viability Rankings

Normal

S-Rank

Chansey

Details:Chansey is by far the most bulkiest special wall in the OU tier.I mean when boosted with evolite and EVs and Nature most physical attacks cannot scratch this pink blob it is that bulky.It learns almost every support move possible starting from heal bell,stealth rocks,thunder wave,wish and toxic
Very few special attackers can hope to break the blob and it is by far the most crucial Pokemon in a normal mono team.Oh yeah it can sweep entire teams by simply toxic stalling them and wearing down with seismic toss.

The Pink Blob Wall:

Porygon-2

Porygon-2 can take on the physical attackers that Chansey could never hope to tank therefore covering the physical spectrum.It can also tank alot of special attacks and wear down the opponent with its modest special attack and solid coverage.Porygon-2 also has reliable recovery.
It has 2 ability Trace allows it to wall certain Pokemon such as gyarados and landorus-t,while Download gives it a boost in an offensive stat which lets it hit hard.

Downloading Duck Tank:

Staraptor

Staraptor is really good for Normal-monotypes. I'd go as far to say that it is essential for any viable Normal-monotype to run a Staraptor, no matter the set.It can run 3 possible sets of which 2 are complete polar opposite to the other.It can run a choice scarf set revenge killing little bitches,a Choice Band set breaking walls like their is no tomorrow and finally a physically bulky set walling many common normal type threats.
Intimidate works well with the bulky set,while Reckless is recommended for the choice band and scarf set for the higher damage output.

Wall Breaker Raptor:

Revenge Raptor:

Lopunny

Lopunny was blessed with a mega this generation which not only got a great typing but a good ability in scrappy letting it kill ghost types such as aegislash and sableye.STAB Return,Fake Out,Hi Jump Kick gives it great coverage backed up by ice punch for more.High speed lets it outspeed almost all non scarf Pokemon except things like Mega Beedrill or Sceptile.However it has a hard time getting past quite a few physical walls such as Slowbro and Skarmory.It also has a nifty resistance to knock off which gives Normal mono troubles.

Punching Power Bunny:

A-Rank

Ditto

Ditto is an unique Pokemon with its ability imposter it can copy can stats boost and transform in to that Pokemon.Not only does it make it a stellar revenge killer but it also puts a risk to the opponent if he dares set up on you.It doesn't have any option only 1 set but its a set only Ditto can run.

The Ditto Killer:

Meloetta

Meloetta's main role on Normal teams is a hard-hitting Special attacker. . Meloetta sports a very high Special Attack stat, and also has a useful sound-based stab in Hyper Voice that will hit through substitutes . Meloetta does good with items like Choice Specs that can increase its damage output to compliment its wall-breaking ability. Meloetta can also run a substitute calm mind set, that can find many opportunities to set up with paralysis support from Chansey/Blissey and Porygon2.

Meloetta also has a unique typing in Psychic / Normal that provides a neat neutrality to fighting move.Also the AV set lets it be a great tank and special wall.

Diggersby

Now listen up from Gen V normal type been hard balled by sturdy steel and rock types,but come Gen VI shits getting messed up with the strongest bunny since azumarill.You think lopunny aint hitting hard enough for you then just call her bro Niggersby.Yeah niggersby with its fucking huge power and STAB Earthquake,yeah you heard right STAB Earthquake.It can break walls and revenge kill at the same time.

All Out Attacker:

Porygon-Z

Porygon-Z is probably one of Normal's best special sweepers, if not the best. Great abilities, good stats, awesome move pool; it has everything it needs to be a successful sweeper. The only Normal type that rivals it is Meloetta. They have the same speed stat (base 90), but Meloetta has far superior bulk and a better typing while Porygon-Z has a higher special attack stat. Because of these differences, it's perfectly acceptable to run both pokemon on the same team without them filling the same role, therefore, there is little reason to not run Porygon-Z if you want a special sweeper on your team.

The Choiced Z:

Double Booster:

Pidgeot

Mega Pidgeot has got somethings going for it in the normal mono scene,for one it is neutral to fighting and with great speed and STAB hurricane can take out a lot of them.Never miss hurricane with a nifty confusion is always nice,good special attacker and heatwave lets it by pass steel types not named Heatran or Empoleon.

Genwunner Bird:

B-Rank

Audino

Normal has always been that iffy monotype that can be amazing, but always got destroyed so badly by fighting that it prevented it from being a top tier threat.
Audino answers normal's prayers, as not only has an amazing defensive stat spread of 103/126/126, but it also sports fairy typing, letting it only take neutral damage from fighting moves.
Having Audino also makes for another user of Heal bell and thunder wave, thankfully clearing up moveslots for Chansey, who is often fighting to use many moves on normal teams; it can make room for a status move or stealth rock.

Support Audino:

Exploud

A 140 base power STAB sound-based move called Boomburst. This move coupled with its hidden ability, Scrappy, can hit anything for some serious damage barring Rock types, Steel types, and the pink blobs (Chansey/Blissey/Porygon2). Even Ghost types and substitute users aren't safe from it!
Specs is really the only item Exploud ever uses, just because who wouldn't want that much power? Its other moves are just to hit the pokemon that can tank Boomburst well. Surf for rock types, a fire move for steel types, and Focus Blast for the few rock and steel types that aren't hit super effectively by water or fire moves (specifically Cradily, Omastar, Kabutops, Empoleon, etc). Its defenses are 104/63/73, so it's not gonna take many hits, but the high HP stat allows it to take one or two if necessary.It also really benefits from sticky web support from Smeargle.

Sound Breaker Set:

Miltank

The Udder from hell has made its return,while mediocre in the normal meta it is a great physical wall in the Normal mono metagame.It chiefly deals with Ice type and Fire type teams,tanking physical hits like no shit.I does have trouble taking fighting type moves and special attacks do trouble it but there is always chansey.

Milky Wall:

Cinccino

Cinccino, one of gen 5's underrated gifts to mono normal is very significant to mono normal as it is a highly versatile pokemon and thanks to its gifted ability of skill link its stab of choice (tail slap) hits 5 times. To add it gains access to bullet seed and rock blast giving it a wide offensive coverage against many of mono types common types (water, flying, ground, ice, fire, bug rock ) means it is hard pressed to be switched in upon as the 5 hits per turn is overwhelming for a majority of pokemon.

Choice Attacker:

All Out Haxer/Attacker:

Ambipom

Ambipom is probably one of the most annoying anti-leads in the metagame.
The combination of priority STAB fake out boosted by Technician coupled with high speed and usable attack stat you really find out whats it really about.
It has some good coverage moves in the form of Knock Off,U-Turn and Low Kick

Anti-Lead:

Last Resort Set:

Smeargle

Smeargle is the ultimate support Pokemon learning every move in the game it can do 2 things for a team.1 set up sticky web and hazards and 2 Baton pass boosts to a strong pokemon.It is extremely frail with pathetic stats and is quite difficult to use more then once,it can possibly be used as a last resort to put a sweeper to sleep

Suicide Support:

Baton Pass:

Heliolisk

Heliolisk lies in a good speed tier of 109 outspeeding Keldeo and such,with 109 SpA it hits decently hard while the electric typing lets it deal with Skarmory and also forms some what of a volt turn core with Diggersby ad Staraptor.

Specs Set:

Snorlax

The king of GSC returns this Gen and he finally Stands.With fantastic bulk albeit a low defense backed up by a good attack STAB not only can this lazy fatass take damage but dish out even more.Solid ability in think fat lets it check Charizard Y quite well and it checks special attackers in general.
Wether your using the CurseLax set to set-up for your foes and crush them under your weight or the AV set to tank any special attack possible or finally the choice banded set to destroy walls like that.

Cruse-Lax:

Assault Vest:

Choice Band:

C-Rank

Blissey

Dont get me wrong blissey isn't a bad Pokemon in mono normal per say its just hopelessly outclassed by its younger blob Chansey.Using blissey you can use leftovers for passive recovery,less susceptibility to knock off(Doesn't mean it can take a knock of though) and better SpA to fire off flamethrower to beat gengar and ferrothron.What you give up though is a Pokemon with arguably better special bulk and significantly better physical bulk.

Pink Blob Older:

Pyroar

Pyroar's niche in a normal mono team is that it gets Fire STAB which allows it t
