Orks and greenskins, the battle-hungry mushrooms from Warhammer
Now things get a bit crazy. Orks in Warhammer 40,000 (or greenskins in Warhammer Fantasy and Age of Sigmar) serve as a model for the Warcraft Orcs, but have little in common with them beyond appearance and a penchant for combat.
Warhammer Orks are literally mushrooms. They reproduce through spores, which mature and grow – either into Orks or, as needed, into smaller Grots or other Orkoids that fulfill various roles in Orc society. Orks are always green, because green is the best color. Even the “Black” Orks are merely very dark green.
Their entire culture is based on fighting and war, not simply out of malice, it is their means of existence. The more battles an Ork participates in and the more opponents he defeats, the bigger and more important he becomes. They are therefore constantly seeking the next WAAAGH!
Interesting side note: Orks possess a special psychic power. If enough Orks believe something, it becomes true, or so the assumption goes. This is why powerful Orks with many followers become ever more powerful and why their impossible weapons work.
If Orks get bored, they suffer. They fight each other in a pinch, and if there is nothing left to do, they die out. Even their exclusive gods Gork and Mork constantly fight against each other.
If an Ork manages to gather a sufficiently large army for a really big WAAAGH!, then he becomes a threat to the whole galaxy or the whole world. So far, that has only rarely happened, and their constant fighting among themselves is one of the reasons why they have not yet wiped out all other factions: All major factions of Warhammer 40,000 in the power ranking – Who could dominate the galaxy?
