Among the classic wrestlers who had face paint, two of the strongest were The Warlord and The Barbarian. They formed the tag team called the "Powers of Pain".

Heads - Jakks WWE Warlord and Barbarian (thanks to Rudotrese for providing)
Base bodies - MOTU Count Marzo
The belt and waist pieces were from different MOTU figures.

I added black straps on the right bicep of Warlord and the left bicep of Barbarian. Their removable ring entrance gear is similar to what they often had on when they came into the arena; for Warlord a vest with chains and for Barbarian a vest with fur.

This is the last of my Masters of the Wrestling Universe series of customs so I thought of bringing back my previous ones for a grand finale. It's the Legion of Doom, Demolition, Ultimate Warrior and Sting versus the Powers of Pain!

Some of the powerful moves that the Powers of Pain used in the ring were powerslams, headlock with hammer fist and elbow strikes, bear hug, jumping clothesline, and a back breaker.
