Name: PKMN-133 EvCUE
Base Form: BuCUE
Colours: Brown & cosmic latte. (VPS armour allows this to change, but it's mostly used in conjunction with the Eon system when Coats are in use)
Description: A smaller, stockier version of the standard BuCUE with a head altered to be rounder and more 'cute'. Basically, it's built to be an eevee version of the BuCUE. It's visibly clearly able to extend in someone areas and collapse in others.
Abilities: Eon system; allows for various option parts to attach (similar to the Planets system in the core gundam), GN Field (production is stored in the 'mane')
Weapons: Biter, Sharp Claws. Hard Tail, Vulcan

Drowned coat
Name: PKMN-133(W) EvCUE Drowned coat
Base Form: BuCUE
Colours: Water blue, plane white, & mud brown.
Description: Additional equipment on the EvCUE that makes it look somewhat fish-like and clearly makes it adapted to water, The feet look slightly muddy. [basically a mecha vaporeon]
New Abilities: Underwater mobility is increased to an incredible degree, Hydro-refraction (Water is manipulated to redirect light around EvCUE)
New Weapons: Cruncher (increased hydraulics on the Biter give it even more bite than normal), Mud Gun (good for clogging joints and intakes as well as blinding foes temporarily)
Special Weapons: Surf (Highly pressurized water is mixed with GN particles to create a destructive battering force that feels like water but is effective enough to damage mobile suits and even push them back, It manifests as a wave.)

Flare coat
Name: PKMN-133(F) Ignition EvCUE
Base Form: BuCUE
Colours: Firery Orange & pastel yellow.
Description: Although looking as big as any other Coated EvCUE form, the most noticable differences are only a new tuft of the 'fur' on top of the hair. [Guess what? mecha Flareon]
New Abilities: Mega Particle Deflection System, Heat-dispersion coating (any heat that affects the surface of the gunpla is disperesed throughout the whole armour, making heat weapons and some beams completely redundant)
Weapons: Hot Fang (sharp blades added to the bitter, they can heat up for extra severing power.), Hot Claws, Flare Gun (flares stick to opponents, damanging them over time and weakening their armour in the affected place).
Special Abilities: High Temperature (The ambient temperature around EvCUE rises to dangerous levels)
Special Weapons: Mystical Fire (A flamethrower-esque attack with crazy range. It's primary function is to damage enemies armaments but it's not unknown that it can destroy opponents entirely.)

Lightning Coat
Name: PKMN-133(E) Lightning EvCUE
Base Form: BuCUE
Colours: Electric Yellow & Cloudly grey.
Description: True to name, it's design looks a lot like a cartoon creature got shocked, at least when the tail and mane are confirmed. [Mecha Jolteon, basically]
New Abilities: Volt Absorb (Any form of 'loose' energy, including but not limited to; mirage colloid, GN particles, and beams disconnected from their source weapon, are absorbed and possibly used by Lightning EvCUE)
New Weapons: Glitch Fang (when an enemy is bitten an electrical shock is sent into the enemy machine that's likely to cause technical issues that take time to resolve.), Electrical Field (exactly what it sounds like, can be used to fire bolts of lightning at targets or change ambient Ionic charge), Thunder Bits (only act as a focus for the Electrical Field)
Special Abilities: Overclock (all remaining energy collected by Volt Absorb is used at once)
Special Weapons: Relentless Charge (Overclocking the MS to the point of self-destruction if no connection is made, this attack involves a simple head-first charge at the enemy. If they somehow survive, their machine will be reeling from the amount of electricity they just got hit with.)

Moonlight Coat
Name: PKMN-133(D) Moonlight EvCUE
Base Form: BuCUE
Colours: Black with a matte topcoat and yellow/blue glows.
Description: The previously thick neck mane has been removed and now the body is much more sleek. Glowing rings adorn it's newly larger 'ears', forehead, and the uppermost joints (shoulders and hips)
New Abilities: Blackout System (Using Mirage Colloid particles a large area around the Gunpla is shrouded in a thick darkness that severely reduces visibility, this area is centered around the EvCUE and is less effective in well-lit areas), Duplicate System; the machine can create images of itself from mirage colloid particles (with a little help from GN particles to recreate glows), Whetstone System (this system wraps weapons of either the user or an ally in GN particles to increase attack power), Punisher System (attack output is increased if the enemy has any kind of buff active.) [although not an actual system of any kind, the glow can be turned off if desired]
New Weapons: Cruncher (more hydraulics in the jaw to increase biting power), Dark cannon (a simple high-powered canon that only seems to fire darkness), Brutal Articulation (the articulation is designed to increase melee attack potency), Pursuit missiles (missiles that are designed to be used against enemies moving away from the user)
Special Abilities: Paranoid Mind (similar to the blackout system, but centers around the enemy machines instead and is always disarmingly effective)

Mystic Coat
Name: PKMN-133(P) Mystic EvCUE
Base Form: BuCUE
Colours: Purple with a little bit of blue
Description: Similarly sleek like the Moonlight coat, this form instead has much flatter ears and a thin, cat-like tail that parts into two at the tip. There's also what appears to be a gem attached to the forehead now. Of course, it's mostly made out of Psyco-frame, but does have the smarts to have actual armour. [Mecha Espeon, you could probably guess]
New Abilities: NT-D, Teleportation (exactly what it sounds like, uses GN particles), I-field, Control jammer (a beam of light is sent from the forehead jewel to the optic of an enemy machine and causes a temporary cascade of glitches in the controls of the target machine).
New Weapons: Telekinesis (exactly what it sounds like), Shield Breaking Fangs (again, exactly what it sounds like), Esper System (using psychic energies, the user can manifest a wild variety of attacks)
Special Weapons: Mindstorm (a colossal amount of psyco-esque energy is manifested into an attack that heavily affects foes.)

Floral Coat
Name: PKMN-133(Gr) Floral EvCUE
Base Form: BuCUE
Colours: Sandy brown and Leaf Green
Description: The majority of the body is the same sleek shape of most Coats and is painted the sandy brown. This one stands out as it's legs are covered in leaf-like structures that are of course green. The ear-antenna are now mostly leaf-like, as is the tail. Along the whole back is a mane of leaves, with one large one at the head. It uses a hover-based movement system and is designed as a ground-type unit. [Mecha Leafeon]
New Abilities: Energy Absorb (same thing that's going on with the Astray Amatsu Mina), Plant Control (mostly useful in forest-type environments), Medicinal fangs (The leg-mounted leaves are useful for patching up damage on other gunpla, not useful for reattaching lost limbs tho), Photosynthesis (exactly what it sounds like, the more time this gunpla spends in the sun, the more power it has.)
New Weapons: Vine Rod (Heat rod, but green), Leaf Blades (The larger leaf-like structures on this coat can be used as weapons, even the tail and ears), Sharp Leaf fangs (The smaller leaves along the back are much like GN Fangs), Link Seed (using the energy absorb system, these pellets can send energy back to the Floral EvCUE over a long distance)
Special Abilities: Overgrowth (Whatever plants would grow in the area are suddenly and quickly sprouted)
Special Weapons: Solar cannon (fires off any energy it can spare, may also hold still to charge it up)

Glacial coat
Name: PKMN-133(I) Glacial EvCUE
Base Form: BuCUE
Colours: Icy blue and Water blue
Description: A sleeker look, again, of the EvCUE. Although it's not particularly insulated-looking it's built to survive frigid colds. The head is surrounded by a solid and dark blue plating, which is also found on the lower legs, and in a diamond shape on the back. The tail is again spread thin, but is clearly intended more like a plow or shovel. Has strong ice-grips on the base of it's feet. [Mecha Glaceon]
New Abilities: Weather Warning (In applicable situations, snow will start), Clear Vision (Methods of obscuring vision via smoke or other small particles are ineffective)
New Weapons: Frigid Bits (Mostly spherical and small bits that can grow ice-like structures on them for either defensive or offensive purposes), Freeze Rifle (exactly what it sounds like), Frigid Wind (a mixture of Mirage Colloid and GN particles is used to create a wind so cold that even arctic-specialized mobile suits may struggle to stand up to it), Freezing Bite (the biter weapon now can freeze upon contact)
Special Abilities: Sudden Hail (Hail starts to fall as the suits Trans-AM capabilities are used, if the weather already turned to snowing then the hail is much worse)
Special Weapons: Glacier Lance (A colossal spike of ice is formed and launched towards the enemy, Exploding into a colossal block of ice and freezing anything in range of said explosion. The area of effect is then made larger if in atmospheric battle by a damaging hailstorm)

Pretty Coat
Name: PKMN-133(Fa) Pretty EvCUE
Base Form: BuCUE
Colours: White, Pink, and Blue.
Description: Sleekly designed, this suit seems designed to be pretty enough to win a beauty competition but is actually just as capable as any other EvCUE coat. It's ear-antennas and tail are pink, with the top of it's body also bearing pink from head to tail, as are it's lower legs. The rest is white. It also bears two small ribbons; one on it's chest, and another on it's head, these are mostly pink with a little bit of white along the 'fold'. From behind these some more Ribbons appear, but these are just Particle Sashes
New Abilities: Calming touch (When Particle Sashes touch a transformed Gunpla which has lore that requires strong emotion it can shut off the transformation), Trans-AM, Nanomachines (various uses, produced internally and can be used offensively or helpfully i.e. healing. based on the Moonlight Butterfly, can be transferred through the Particle Sash), Moonlight System (used to power up the nanomachine production, particle wonderland, and other fun super-attacks. It's basically the Satellite system but with a smaller area necessary)
New Weapons: Particle Sash (used to make ribbons that are animated and capable of incredibly fast movement. can be defensively used or offensively used), Fairy Wind (a small amount of Nanomachines is used to kick up a wind and do damage to enemy machines), Draining Kiss (the Biter system can now steal energy)
Special Abilities: Nonsense-AM (Trans-AM, but much more powerful and colored Pink, weird shit starts to happen when activated)
Special Weapons: Moonblast (almost all the energy stored in the MS is fired out), Play Rough (The Moonlight system is used to increase the power in the Particle Sashes, allowing it to batter other gunpla with beyond destructive force at blurry speeds)

Cadaver coat
Name: PKMN-133(Gh) Cadaver EvCUE
Base Form: BuCUE
Colours: Low-saturated blue & navy, grey, low-saturated green & dark green, Low-saturated Reds.
Description: All the parts of the Cadaver coat are coated to look like they were dug out of the ground and re-used. It's all made out of spare parts from even outside the Gunpla series, and are made to look like the parts were fashioned together to make the coat. It's a highly irregular shape, Several hardpoints are present and around the neck is a rail for a pair of mechanical arms (taken from the Ball) and it's covered in Gunpla hardpoints. Has two large screw-shaped structures on the shoulders/back. (it's mostly made up of 30 minute missions kits)
New Abilities: Frankenstein System (loose gunpla parts can be attached to the hard points and controlled like they were always part of the gunpla, can also be used to fix back on missing limbs from ally gunpla or fix enemy limbs as a replacement for any ally's missing limbs. )
New Weapons: Brutal Claws (dangerously irregular blades on the claws may or may not be upcycled scalpel and nipper blades), Vile Jaws (Similar to the Cruncher seen on other EvCUE forms, but there's additional teeth and it's set up to just mangle any physical object that gets inside), Chainsaw (mounted onto the tail as an extendable weapon)
Special Abilities: Resurrection System (If sufficient energy is provided via being shot into the screw-shaped structures on the back, then the Cadaver EvCUE will come back to life, but won't be able to use any other coat until proper repairs are made.)

No reference images avaliable I'm afraid.
