I've got a couple I posted a while back, suppose I may as well repost them here. Worth noting that my Hobgoblins are much more elite than the norm, and you might want to nerf them a bit if you want standard fantasy Hobgoblins.
Hobgoblins
Hobgoblin, Group, Organized, Intelligent, Cautious
Longsword (d8 damage), 6 HP, 3 Armor
Close
Instinct: Follow orders
Hobgoblins are brutal conquistadors, preying on weak nations nearby for fresh supplies of slave labor and natural resources. The fact that they form organized, self-sustaining nations means you can establish surprisingly cordial trade relations, sure, but have you considered the drawbacks of combining a goblin's cruelty with a human's capability for strategy and logistics, not to mention their taste for imperialism?
-Volley with longbows from a safe distance
-Form a defensive formation with allies and advance into unconquered territory
-Make a tactical retreat, and return with reinforcements
Hobgoblin Champion, Solitary, Organized, Intelligent, Messy
Axe or Longsword (2d10+2*b damage, 2 piercing), 16 HP, 2 Armor
Close
Instinct: Seek glory in battle
Skilled warriors trained with an almost fanatical desire to win glory in battle, but no less capable of working within the strictly organized Hobgoblin warbands, these champions are fearsome opponents on the battlefield, an elite class that often come to receive more respect from their underlings than the officers who actually lead the armies.
-Charge heedlessly into battle
-Cleave through multiple opponents at once
Hobgoblin officer, Solitary, Organized, Intelligent, Cautious
Longsword (d10 damage), 12 HP, 3 Armor
Instinct: To conquer
Someone's got to be on top of the hierarchy.
-Direct minions
-Sack vulnerable steadings
Bubgear, Group, Intelligent, Large, Forceful, Messy
Mace (d8+3 damage, 1 Piercing), 10 HP, 1 Armor
Close, Reach
Instinct: To bully weaker creatures
Rarely less than 8-feet tall, these creatures are what happens when you crossbreed goblins with ogres. Though not quite as tall as their ogrish ancestors, they are more than willing to demonstrate that they are nonetheless quite capable of caving in the skull of anyone who should irritate them.
-Hurl boulders
-Accept tribute from lackeys
Demons and Devils
Succubus, Solitary, Stealthy, Devious, Intelligent, Planar
Barbed wings (d6 damage), 12 HP
Close
Special Qualities: Wings
If you don't know the gist of this one, you're probably too young anyway. Steals your soul with a kiss, never seems to be wearing more than about a yard of fabric, etc. etc.
Instinct: To steal the souls of mortals
-Seduce a mortal
-Steal life and energy with a kiss
-Turn friends and allies against one another
Marilith, Solitary, Large, Messy, Intelligent, Cautious, Planar
Scimitars (2d10*b+3 damage, 2 Piercing), 16 HP, 2 Armor
Close, Reach
Special Qualities: Six-armed
Instinct: To slaughter the enemies of Hell
One of the most fearsome fiends the lower planes have yet produced, bottom half of a snake, top half of a woman, nearly ten feet tall all told, and with six arms, each wielding a hell-forged scimitar of steel that carves through armor like it were made of paper. And worse, they're rarely caught without a posse of fiendish followers or cultists mad enough to summon the thing...
-Attack with multiple weapons
-Conjure Hellfire
-Direct fiendish minions
Balor, Solitary, Huge, Magical, Forceful, Intelligent, Planar, Terrifying
Sword of flame (2d10*b+7 damage, ignores armor), 20 HP, 4 Armor
Reach
Special Qualities: Wings, wreathed in flame
Instinct: To bring torment and despair to mortals
Demonic generals wreathed in fire and fueled by nothing but hate and the consumed souls of the innocent, the Balors are the most terrifying creatures ever to emerge from the pits of Hell. Even to draw near to them is to risk your skin being melted off by the searing heat and raw evil that radiates from them at all times.
-Consume those nearby with overwhelming aura of evil and terror
-Direct the armies of Hell
-Conjure Hellfire
-Manipulate mortals into summoning itself or its minions into the Material Plane
Bearded Devil, Group, Large, Intelligent, Planar, Messy, Organized
Vicious spear (2d8*b+3 damage, 2 piercing), 10 HP, 2 Armor
Close, Reach
Instinct: To destroy the enemies of the lower planes
The feared shock troopers of the lower planes, powerful demons and devils are often accompanied by a squad of these creatures as bodyguards.
-Charge the enemy with spears leveled
-Intimidate mortals into offering tribute or summoning allies
Erinyes, Solitary, Intelligent, Planar, Messy
Burning longsword (2d10*b+2 damage, 3 Piercing), 12 HP, 5 Armor
Close
Special Qualities: Wings
Instinct: To conquer the enemies of Hell
These angels of Hell are some of the highest ranking officers in the hierarchies of the lower planes. Though typically encountered alone (or at least, not with others of their own kind), demonic generals like Balors will often have two or three on hand as bodyguards and advisors.
-Conjure Hellfire
-Cleave through multiple enemies in one fell sweep of her sword
-Direct fiendish minions
