Woohoo ! Im the first to mention: BULLS !

I really dont understand why nobody has mentioned them before, the bull symbol is nice and powerfull symbol i think.
Not sure they would be my number 1 though.
In no specific order:
- Wolves
- Bulls
- Forrestmen
These three mix well together aswell i think, with the brown and green colors they must be the rebels (like Bruce said)
The Bulls even got some green on their torso's:

I usually use them with green legs with a black belt, and mix the wolves and forrestmen shields with the bulls aswell.
Seconds in my favorites list are:
- Fright Knights
- Knights Kingdom 1 (for those great king Leo's torso)
I use the King Leo's torso's (the dark grey chains/plates) with Fright Knight shields and skelton

heads to form my ultimate Evil Army !! Mwuhahahah !
