Very much so! Luckily and thankfully a fellow boarie is kindly selling me his!
But to answer you question, I put the helmet in the small over I used to bake my sculpts in but at the lowest temp and only left it in there for like 3mins to try and soften up the plastic b/c the hair dryer I was using wasn't getting the plastic soft enough to bend. Once the timer went off I took it out and one ear/wing was totally folded and the helmet shrunk. I tried to pop it on Thor's head while it was still a bit hot to hopefully at least get the shape of the helmet back but it cooled so quickly that it was already too late. Lessons learned, don't try to mod things the quick and easy way. For someone who's been customizing figures for years now, it's is pretty embarrassing to have done such a newb move
