Misdreavus
In a tier devoid of choice for defensive Ghost type Pokemon Misdreavus' 60/60/85 defences are not stellar but enhanced by Eviolite become bulky indeed. Acting as one of the only spin blocker in NU Misdreavus is a common sight on teams, gaining perfect coverage with Shadow Ball and HP Fighting which can both hurt coming off 85 SpA while it can outspeed much of the tier with 85 Spe. Supportwise Misdreavus has access to Will-O-Wisp to boost its Defense and Taunt to shut down walls. It is often seen carrying Substitute to ease prediction and allow it a chance against Absol.
Unfortunately Absol is everywhere and while it must watch out for HP Fighting it has both Sucker Punch and Night Slash to bring a quick end to Misdreavus. Swellow also fears little that Misdreavus can do due to Guts and an immunity to Shadow Ball.

Bronzor
Bronzor possesses dual screens, stealth rock, gravity, toxic and trick room making for an excellent supporter. It's 57/86/86 defenses become immense after applying Eviolite's boost to them. Its Steel/Psychic typing is a blessing for it leaving it with only one weakness and a large number of resists and immunities. It acts as a solid counter to the birds however being able to status them and set up screens in their faces.
However it lacks any sort of offensive presence with 24/24 offenses and is exceptionally slow, barely out speeding Torkoal with 23 Spe. This makes it set up bait and it is exceptionally taunt weak.

Natu
Natu is notable for being the only Pokémon in NU with the ability of Magic Bounce. This makes it an excellent status absorber and allows it to prevent entry hazards from being laid. Unlike Bronzor its 40/45/45 will not impress anyone with or without Eviolite however it does have passable offenses of 50/70/70 and access to Roost which allows it to keep healthy.
Its support movepool is large, containing dual screens, Thunder Wave, Toxic, Sunny Day and Rain Dance, Trick Room, Tailwind, and Power / Guard Swap. Its ability also allows it to participate in a Baton Pass chain and reflect phasing attempts.

Murkrow
Murkrow distinguishes itself with the ability Prankster allowing its non-attacking moves to gain +1 priority. 60/42/42 defenses aren't worth writing home about however become passable with Eviolite.
It possesses Featherdance, Mean Look and Roost allowing it to stall out physical attackers despite its low defensive stats. It is one of the fastest weather starters in the tier with a priority Rain Dance and Sunny Day along with Tailwind to speed other Pokémon up. However it is forced to choose between Damp / Heat Rock or Eviolite which is a major weakness for it as a weather starter. Its priority Thunder Wave, Toxic, Taunt and Torment allow it to shut down many Pokémon.
Other than that it has 85/85/91 offences which while passable in NU are outclassed in an offensive role.

Wartortle
Wartortle is notable only for possessing Rapid Spin. It has mediocre offenses but its 59/80/80 defenses combined with a good defensive typing are impressive when boosted by an Eviolite.

Baltoy
Baltoy also fulfills the role of a Rapid Spinner and has a unique typing and ability which gives it an immunity to both Electric and Ground. Its 40/55/70 defenses display its weak physical bulk but reasonable special bulk after Eviolite.

Tangela
Tangela has a wide support movepool, a usable Special Attack and immense physical defense. 65/115/40 defenses with Eviolite applied are enormous, being able to tank a Guts Swellow Brave Bird and still be standing at the end of it. It also possesses Regenerator, Leech Seed and Giga Drain to heal it along with Sleep Powder to stop it being set up bait,

Golbat
Golbat has several unique moves to set it apart from other Eviolite users. It's unique typing gives it 3 4X resists and its 75/70/75 defenses are huge when enhanced with Eviolite.
90 Spe stat means that it possesses a fast taunt, haze and can as a fast, bulky weather starter as well. Unfortunately for all NFE weather starters it is forced into the choice of Eviolite or a Rock of its choice to extend the weather, making it mostly outclassed as a weather starter. It has Whirlwind to rack up more hazard damage, Super Fang to cripple opposing Pokémon as well as Roost to heal itself. All in all Golbat is a top tier Pokémon and wall.

Shelgon
65/100/50 defences aren't something you call home to tell mum you met but after Eviolite combined with Dragon's innate elemental resistances become impressive. Backed by a 95 Atk stat Shelgon is not to be underestimated. Able to Wish / Protect and pass Wishes Shelgon is a versatile Pokemon. It also possesses Dragon Dance if you're so inclined for a bulky set up sweeper.
(TBH I thought he was Rock/Dragon for a while. That would a cool middle finger to Swellow.)

Fraxure
In a tier devoid of Dragons and Steels Fraxure stands out notable for its combination of one of the best boosting moves and a massively powerful Outrage. Fraxure possesses an amazing 117 Atk stat which finds itself boosted with Dragon Dance. 67 Speed is just enough once boosted with Dragon Dance and spamming Outrage is a relatively safe proposition in a tier with virtually non existent steels.

Gabite
Gabite is a different beast from Fraxure. Fraxure possesses much more power off the bat while Gabite has a lovely STAB Earthquake that Fraxure lacks. Gabite also possesses 82 Speed, however lacks Dragon Dance, a serious blow to it. Substitute and Hone Claws allow it to boost with its virtually unresisted STABs and allows it to choose Dragon Rush over Outrage which possesses most of the power of Outrage without being locked in and the low accuracy is boosted by Hone Claws.

Scraggy
Scraggy is quite literally a little Scrafty. It possesses its big brother's advantages of nearly unresisted dual STABs and fears nothing from most Psychic types, something most Fighting types would give their right hand to have.
It commonly runs a Bulk Up set or more offensive variants run Dragon Dance. For Fighting STAB the two most common options are High Jump Kick which grants it amazing power or Drain Punch which enhances its longevity. For Dark STAB it chooses between Crunch and Payback generally choosing based upon whether Bulk Up (Payback) or Dragon Dance (HJK) was chosen. Bulk Up generally runs Shed Rest to regain health while Dragon Dance can choose to run it but generally will not survive if Shed Skin doesn't activate. Gifted with the abilities of Moxie or Shed Skin it can choose a virtual immunity to status or to become an unstoppable wrecking ball with each KO granting it additional power.

Gurdurr
Gurdurr possesses an excellent 105 Atk stat which sees use as a bulky set upper. Generally seen Bulk Uping and then using a combination of Drain Punch, Payback and Mach Punch to deal immense damage, strong special attacks are required to muscle past its Eviolite increased 85/85/50 defenses.

Duosion
Duosion, much like Gurdurr, acts as a bulky Calm Minder from the special side of the spectrum. 65/50/60 defenses aren't worth writing home about but with 125 SpA it hits like a truck. It possess Recover so powerful attackers are necessary to stop it before it gains too many boosts.

Piloswine
Piloswine possesses an interesting typing of Ground/Ice which while substandard defensively, as is every Pokemon featuring Ice, has amazing STABs. With 100 Atk Piloswine can hit hard and has high powered moves to back it up. Ice Shard allows it to revenge weakened birds, while Icicle Crash and Earthquake allow it to destroy most Pokemon. 50 Speed means Avalanche is a viable alternative to Icicle Crash. It also possesses Stone Edge to give it EdgeQuake coverage and Roar and Stealth Rock if you'd prefer a supporter. It also possesses dual screens but has better things to do. Finally Superpower affords it Fighting coverage although forces it to switch.

Electabuzz
Electabuzz is most commonly seen as a scarfer, however faces competition from Rotom-S who possesses an additional STAB which hits the bulky Grass types and Fighting types hard. Electabuzz has relatively mediocre defenses possessing only 65/57/85 stats however with Eviolite these become reasonably bulky. Combined with its fairly impressive 83/95/105 offenses allowing it to easily go mixed, it represents a different breed to the other Eviolite Pokémon being neither a support Pokémon or a bulky set upper but rather a bulky tank capable of both delivering and taking hits.

Vigoroth
Vigoroth has a key advantage its evolution lacks: namely not being a piece of s***. (I'm kidding. Everyone just chill out) Despite fierce competition from the large amount of normal types who populate NU Vigoroth has several advantages other Normals lack including 80/80/55 bulk before Eviolite and a lovely 90 Speed to run and do damage with his 80 Atk which is passable in NU. Sadly its Physical movepool is lacking being forced to rely on Brick Break for coverage. Luckily it gets Earthquake to aid it and sadly no Stone Miss instead relying on Rock Slide.
So go discuss! Are they merely limited versions of their fully evolved forms or does the inferior offenses and enhanced defenses create a different kind of Pokémon? Are there fully evolved Pokémon who can do the job they're doing better? Is the loss of an item choice a deal breaker?
If I've forgotten any Pokémon tell me and I'll add them.
Edit: This thread wasn't really intended as an absolute guide to NFE in NU and and mistakes were *heh* made. Thanks for bearing with us and hopefully this edit should *heh* bring things up to standard.
