Eternia has a new Black hero. Sun-Man, a muscular action figure sold in the '80s that was born from the need for a diverse alternative to He-Man, will join Mattel's Masters of the Universe roster, giving a new generation of children the chance to pair up He-Man and Sun-Man in the battle against evil. The addition of what may be the first Black superhero toy comes amid a big push by Mattel to reinvigorate the Masters of the Universe line.
