Ron Pearlman dressed up as Hellboy to make a kid's Make-A-Wish wish!

The Make a Wish Foundation was looking for someone to play Hellboy, there was only one person they wanted. Ron Perlman is known for playing the title character in Guillermo del Toro's film's "Hellboy" and "Hellboy 2." When the 62-year-old actor heard that six-year-old Zachary's wish was to meet Hellboy, he was all for it.

Zachary, who was suffering from leukemia, told the Make a Wish Foundation that he wanted to "meet and become Hellboy." So they made it happen. Perlman underwent the four hours of makeup and costuming required to make himself Hellboy and then met with Zachary.

The two then spent the day together. Later, Zachary got the chance to become a miniature Hellboy himself.
