The proper term for "man-child" would be "Vulnerable Adult". I think for the usage you describe, it is "Immature/Immaturity" you want. Although to cover multiple age brackets then "Spoiled"/"Spoiled Rotten" would work best. That's if it has any bearing on being a villain.

Recommend we avoid "man-child" in any official context as that also tends to be applied to autistics, and we don't want to suggest that in any way.
