So I have a lot of orcs minis. We've been over that before.
I have orcs from Wargames Factory, TSR, Reaper (Dark Heaven Legends and Warlord-style Bones), Copplestone, Games Workshop, Dark Ages (I think that's the name), and three kinds from Black Tree Designs (one being old Harbringer orcs, I think). Plus some others, probably.
That doesn't count the goblins, hobgoblins, and whatever else I thought was sufficiently orc-like to convert to orcs.
So my orcs are sometimes pig-faced, sometimes flat-faced. Sometimes they have fangs. Some have big heads. Some have smallish heads. Some have thick bodies. Some narrow. Some I got too heavy-handed with the black wash.
So how about some variations?
All of these are just random ideas.
Traits: Add Acute Taste and Smell 3, Overweight, and increase HP by 2.
Traits: Add the Ravenous trait (GURPS Dungeon Fantasy Monsters 1, p. 38).
Traits: Raise SM to +1. Add +3 to ST and HP.
Traits: Lower SM to -1. Reduce ST and HP by 2; add Striking ST 2 so you don't have to change their damage lines on the writeup.
Traits: Add DR 3 (Tough Skin, Does Not Stack With Armor). Remove encumbrance from armor.
Traits: Add +1 to IQ and DX and add Magery 0 to traits.
Traits: Add Ambidexterity, Special Training (Two-Weapon Fighting without TBAM or WM), and Two-Weapon Fighting (Dungeon Fantasy 3: The Next Level, p. 41).
The only weird one up there is the Dark Orcs thing. But in some games I played, "black orcs" were the smarter, nastier orcs. So, that's one way to deal with my overabundance of black wash - I'm making them smarter and nimbler, not a color and wash error.
These all stack except that you can't have Small Big Orcs. But Big Fanged Orcs? Yep. Small Barbaric Dark Orcs? Big Dark Fanged Pig-Faced Two-Weapon Orcs? Sure!
