Destro.
Sounds like a joke, but the head is only painted silver. Unlike the '83 Destro, which had a very stylized bald-Bizarro look to it, the 25A really just looks like a bald head.
I was planning on painting/sculpting hair on a Destro head to make a Steeler custom. Now that Hasbro's got one on the way, I'm just going to wait for that head instead.
