This is nothing short of awesome.
Ron Perlman brought his "Hellboy" alter-ego out of retirement for a very special cause -- applying the makeup once again to help a Make-A-Wish come true.
According to Spectral Motion (via SuperHeroHype), the special effects house that worked on the two "Hellboy" flicks, Zachary (seen above with Ron) wanted to meet and become the red, horned comic book hero for a day.
With Spectral Motion's help, Perlman was transformed into the hulking hero -- an idea he reportedly "loved."
Zachary was also done up in red makeup so he could step into Hellboy's hooves for a bit too.
Check out the great photos above.
