This was a fun project for a fellow collector/fwoosher. He asked me to use Discogod's Ankle Rocker tutorial from the fwoosh boards to modify and shorten his MS Colossus to make him fit in better scale with Marvel Legends figures, and also modify and make the two ML Colossus heads interchangeable. I did have to use some apoxie sculpt to build up the back of the ML heads, and then paint the Series 5 Colossus head to match. The only problem I have is that I'm going to have to do this to my MS Colossus now :)
