The group was ready to stop whatever Brad was doing until they all noticed that the possessed helm was on his head. They had not seen his beast for some time and were sure that he had been waiting for it to fully absorb the black iron shield and the black iron sword. However, they were all unsure what was going on now.
"Clark?" Ralph wanted to make a move and stop Brad. he had the most resistance to metal and fire besides Reese. The sudden heat that seemed to be coming from Brad wasn't because of fire though. It was like he had a bad reaction to something and was having a fever.
"Just wait. I want to stop him too but the possessed helm just condensed all the metal it consumed in to itself and should fully change now. Brad is just suffering the side effects of it." Clark rarely found himself struggling with these kinds of things. He had no way to make things better for Brad who was being put through a massive release of metal energy.
Brad might just be the wild card when it comes to a tanky berserker
