I'll take Dustman/Waste collector as a class.

* They get a bonus to finding things (search checks)
* Can pull useful objects not listed on their character sheet out of their backpack because "you'll never believe what people throw out"
* Bonus to saves against poison and disease
* Bonus to max carry weight

Race Ant-Men

Low HP, but regenerating Limbs,
No body Armor (Maybe his Exoskeleton as a fixed Body-Armor),
but can wear Cloaks, Belts -- maybe Helmets and maybe Boots
High Strength because of being an Ant
Can wear 2 2H Weapons or 4 1H Weapons 2 Shield 2 Swords etc.
They can detect Magic / Magic Traps with the Antennas and got 150% Magica
Good Offensive Spell caster dual-cast, for example 2 Fireballs
Good Rogue / Thief / Damage-Dealing Melee

From their secret Kingdom located in hidden Underworld Labyrinths of the vast Desert and far away Hills scouts
of Formica-Man (from lat. Formicidae / Ant) traveled to the domains of Elves, Dwarfs and Man to find more people to make into
their subjects, to feed their larvae,lands to exploit for resources or mighty empires to have (at least for the moment) some
cultural exchange or working together. Tho their language is hard to learn and even harder to talk in for most humanoid races, their
language is rich and expressive. Their knowledge in Smiting Weapons and Spell making is high and there are skilled in combat and magic,
while they are strong, their bodies are weak, and they like to send out massive force when in war.

Class: asylum lunatic. Each round in combat there is a chance you will lose control of your character and do something random. This effect is negated if you are in an asylum itself. People are unsettled by your presence, giving you a bonus to intimidate and major penalty to diplomacy.

Subclasses:

- psychopath: specializes in persuasion. Diplomacy penalty does not apply.

- serial killer: specializes in stealth

- cult leader: has divine powers

- psychotic: bonus to damage. Occasionally attacks hallucinations.

- paranoid: immune to sneak attacks, mind control, and charm. A character using diplomacy against this sub-type always fails. This character is too dysfunctional to be in a party, and is always on his/her own.

The Necromancer
#GOGxPathfinder

Class: Faceman

Desc: Persuasive innate spellcaster. Attractive. Lots of illusion, confusion and trickery spells. Likewise has strong immunities to the same. But no combat spells whatsoever. Excellent when fighting defensively; terrible when going on the offense. However he gets unlimited attacks of opportunity. A chance each round to distract main opponent. Can only use a rapier. Refuses to wear armor but gets double bonus from all ring, necklace, accessory effects. Must wear fancy clothes and eat good food. If he does not sleep in a nice bed, eat good food, etc, he gets a debuff. Excellent slight of hand. Every time he talks to someone there's a chance he'll pick their pocket. Gets a heavy discount at inns and shops because everyone knows him.

At some mid level, he gets a personal assistant who will carry all his loot, fix his stuff and defend him when necessary. Perhaps he can choose between several types: secretary, bodyguard, lover, etc.

At high levels he can hypnotize and seduce opponents without spells, even demons and the like are not immune to his charms.

I know my suggestion is not original. But as I see there is already a fox in the image (Kitsune I presume?).

I am a big fan of Warhammer Fantasy and miss something like Skaven in other fantasy games.
To avoid copyright issues of course without the machinery they use in WF.
But I think they could make excellent infiltration and spy units.

Oh yes, another good sneaky infiltration/spy unit would be something like a Khajiit..Kerran? No idea how they are called in this game world. But by some many critters in that world I am sure there is something like that.

That would be lovely to have something like one of those added, maybe both.

A fantasy RPG needs a sci-fi twist.

Class: Time traveler from an advanced, distant future

In addition to pocket-sized death ray guns and dehydrated ice cream, they have access to the equivalent of the internet and can look up the general outcomes of historical events but they'll need hours to do in-depth research sifting through thousands of years worth of a spottily recorded past. They can even look up a walkthrough for Pathfinder and discover where any secrets are hidden.

How about a sapper, something like a crazed explosives expert (or at least... explosives enthusiast). They'd be able to set explosive traps to deal devastating damage to enemies, but with the risk of backfiring and blasting themselves or their party. Renegade!

For race I don't want something new but rather a race that isn't playable. I want goblins to be playable because the idea of a little silly green guy at the head of the crusade trying to figure things out is just too funny. Goblins are awesome, period.

And for a class, with the theme of the game being playing as a powerful commander I want a class specialized as a summoner, a class capable of summoning a permanent companion from a pool of creatures or even better capture creatures he defeats to later summon them. Pathfinder Pokémon!!!

CLAIRSENTIENT
Have the ability to get psychic information through sensing and feeling the energies around them. Their ability also gives them to understand other creature’s feelings, by tuning into them. Clairsentients may also serve as a medium for the dead and relay information by their ability to feel. They can also get another creature’s feelings and emotions enabling them to help in solving problems being encountered and further help in making a decision. Clairsentients are also alcohol or drug dependent to ease the dark and negative feelings that they receive.

Telepathy: Mentally interact with other minds.
Zoolingualism: Communicate with animals.
Presentiment: Detect emotional resonances from other locations/times.
Mentokinesis: Ability to control the mind and creating illusions.

That class actually exists if the psionics rules are in use; it's one of the specializations available to the Psion.

Engineer

A class with the ability to conceive, construct and handle mechanical devices. Such devices would include some weapons like muskets and other primitive firearms (although they would not handle them as efficiently as gunslingers), as well as more complex siege engines like catapults or trebuchets, and even canons and flamethrowers. Other possibilities could be some mechanical traps that could be layed on the ground to catch small game or hurt enemies.
The class would be also skilled at spotting and disarming mechanical traps.

Starting skills :
Craft (mechanical)
Disable device
Knowledge (engineering)
Profession (engineer)

Hit die : d8
Proficiency with medium armor, simple and martial weapons

This isn't exactly original, but what about aTwo Headed Troll:

Great bonus to Strenght, Constitution, some to Dexterity, and massive penalties to Int and Charisma.

Regeneration, Superior Two Weapon Fighting, Darkvision, Rock throwing and possibly a Tyranossaurus as an Animal Companion/mount.

New race: Harbinger of The One

Completely incorporeal, the Harbinger of The One is an echo of an all-powerful god residing in another dimension.
Its objective is to expand the faith of The One across the multiverse, slowly erasing the other faiths until only one remains and the universe can be absorbed into the One Kingdom.

The Harbinger has no stats. It possesses the faithful and uses their bodies (along with any gameplay benefit) to further its goal. It cannot gain experience and level up, but when the body dies the Harbinger's spirit immediately possesses another faithful; in case none are nearby, its ghostly form can move freely, unseen, invulnerable and unable to interact with anything. Only True Sight can reveal it in this state, and only a direct intervention of a Deity can destroy it.

New class: Puppet Master

Mentally strong, but vulnerable while using ability, so works in the background, avoiding attention.

Can temporarily (duration depends on level of PM and target) completely control others and force them to do and say what the PM wants.

While doing this, the PM itself appears in a comatose state, unaware of their surroundings. So finding a good safe place to operate is paramount.

Powerful ability combined with limiting weakness makes the class an interesting challeng to play. Would also make for great NPC villains :-)
