Since the sinister forces led by the villainous Black Hole (a.k.a. "Professor Darkness"™) have vowed to destroy the solar system, the brave and resourceful Planet Heroes™ were formed to protect the peaceful planets from danger and disaster. Ruthless, scary, and bad to the bone, he's a hulking nightmare of twisted ambition and seething destruction. He never goes many light years without his corrupt little Comet "Photon"™ & Comet "Neutron"™ who race across the universe to do the devious dirty work of the guy they call "Professor Darkness™". From Alpha Centauri to the North Pole, nobody is safe from the power of "Professor Darkness" (Black Hole)! Includes 3 replaceable mercury-free button-cell batteries.

Frequently Asked Questions

  • What are the best kind of batteries to use in Fisher-Price® and Mattel® products?

    A.    We recommend using alkaline batteries with our products, as they are great for long-term use and help optimize performance. We don't recommend using Carbon-Zinc batteries. While Carbon-Zinc batteries may work well with low-power devices, they can drain after a short period of time and cause certain products to not function properly.
