Fan Casting MCU: The Power Pack

Alex (age 12), Julie (10), Jack (8), and Katie(5) are the children of Dr. Joseph Power and his wife Marion. Dr. Power was about to finish construction of a matter/anti-matter converter that he hoped would solve the energy crisis. A member of an alien race called the Kymellians tried to warn Dr. Power of the danger of the converter, but he was gravely injured by the Zn'rx, or Snarks, a reptilian race of evil aliens. The Kymellians kidnapped Dr. Power and his wife and took them to their home planet. Meanwhile, lost in the woods, the children found the downed starship that contained the injured Kymellian. With his dying breath, the friendly alien gave them four special abilities, split evenly, which granted them superpowers, and use of his smart-ship. The Power children used their powers and ship to rescue their parents and stop the Snarks from making the converter into a weapon. Their parents unaware of the kids's new heroic identities, the kids now fight evil as "The Power Pack".
