An Advanced Creature Profile by Vincent Groth.     

The Horned Giant stand twenty feet tall with heavily sun kissed skin. The Horned Giant is not actually a greenskin but have been integrated into the Horde as a mercenary corp. The Horned Giant has a long gnarled nose, large ears, big manes of rough wooly hair, and thick brows. They have large horns they carve into intricate designs like standing rune stones.  They tattoo their skin with woad and red berries and pierce their thick hides with weapons of their foes.  

The Horned Giant like most giants are immensely strong using their giant mass to purposeful work. While most giants rely on brute force Horned Giants seem to be smart enough to develop skills and some degree of tactics. They have thick skin that will stop all but magic and siege weapons and have actual smiths shaping actual weapons for the Horned Giants.  

Horned Giants were once a nomadic people but found all they could want as serving the Horde as mercenaries. 

The Horned Giants have many reproduction issues due to their size and mate only once every ten years and have long development cycles unlike their horde bound allies.
