A very fun and very smart comic book that most definitely should be read in physical form.
Our hero's power stems from the comic as a medium, so that he is able to move between panels and use storytelling conventions (such as someone narrating a scene set in the north pole so that he can travel there) to defeat villains. The humor is witty and the characters loveable.

This seems like it'd be a great pick for a parent to read with their child: there are a lot of physics shenanigans and intricate interactions that - while not difficult to understand - benefit from pausing, wrapping your head around and understanding.
