Kid or not, these super heroes (and some villains) are 100% committed to their personas.
Being 3 feet tall won't stop Thor from raising to the skies to invoke the strength of lightning. Magneto will go inside when his mother calls him for dinner, but not until he rips the swings off their chains. Even Wolverine's tree-branch claws don't get in the way of his feisty battles and brute attitude.
Don't let their cuteness mislead you. They've got just as much passion as if they were fully grown, adult super heroes. Click through the gallery for a few other selects, and be sure to expand to get the full effect.
