Used Piledriver's body and waist. For the arms I used Piledriver's shoulder joint and gloves with Colossus' arms. Also used Colossus' thighs with ROHML Thor's boots. I always thought Thunderball's head sculpt resembled Colossus so I sculpted the hair and it was a good look. I added Omega Red's belt and finished it of with the paint app.
Love your collection!
