Befriending Devil Dinosaur
Moon Boy befriended and aided a huge red reptile named Devil Dinosaur for years and the two had adventures together ever since. Moon Boy is somehow able to make the creature understand his ideas or what they should do.
Fallen Angels
Moon Boy and Devil Dinosaur where hurled into the present day where they fought alongside mutant superheroes such as Multiple Man, Boomer, Warlock and Sunspot. The team would become known as the Fallen Angels. After some months of spending time with the group, they disbanded and Moonboy and Devil Dinosaur where brought to the Savage Land, a modern day wilderness in the middle of Antarctica. It was much like the environment Moon Boy and Devil Dinosaur where familiar with, so a good home for the two.
Heroes for Hire
Moon Boy was eventually kidnapped by a group of superheroes named the Heroes for Hire whom sought to bring him back to a lab so experiments could be done with him. Most of the group firstly where ok with this mission, until they started to know Moon Boy and felled it would be a crime to take him away from his normal habitat. The group eventually agreed to leave Moon Boy behind. Unfortunately, the mercenary known as Paladin was not part of this agreement and stole Moon Boy either way. Eventually the other members of the group managed to free him and return him to the Savage Land and his friend, the Devil Dinosaur.
Skaar, Spider-Man and Return to the Past
Devil Dinosaur and Moon Boy fought with Skaar, the son of the Hulk in the Savage Land. Some months later, Moonboy was found by the Fantastic Four (after Spider-man fought the duo) and both Devil Dinosaur as Moonboy where placed back in the past.
