It was a very simple custom job, the whole thing took about 30 minutes to do... I used the Hydro torso's from the Marvel Select Spider-Woman figure base and just dremeled and hollowed the bottoms out. I had some unknown army soldiers figures laying around and just removed their lower bodies and added a little super glue then plugged it into the Hydra torso and they just fit perfectly...I have the regular Marvel Legends Hydra Soldier figure but I just like the way the army pants on these custom soldiers make them look alittle tougher....Enjoy
