What Defines a Marvel Sidekick? Understanding Their Role and Importance

In the Marvel Universe, a sidekick isn't just a secondary character tagging along; they are essential partners who complement the hero’s journey in meaningful ways. Typically, a Marvel sidekick is a younger or less experienced hero who supports the main protagonist, providing assistance in battles, intelligence, or emotional strength. Their role often involves growth from a novice to a capable warrior or leader, offering readers a relatable point of entry into complex storylines.

Sidekicks serve several critical functions:

1. Humanizing the Hero – By sharing personal struggles and victories, sidekicks make legendary superheroes more approachable and grounded.
