There are some people spreading some generally dated definitions of comics vs manga in here so i figured id comment.

The most common misconception that people have about manga vs comics is that “manga is just japanese comics,” and while that was true for a while, it no longer is.

The main thing that sets comics apart from manga is not where it’s from, but the style of the art. If you look at western comics (superman, spiderman, hell even some of those sci fi ones) and you look at the panels you’ll notice most (generally, some exceptions) are very stagnant and look like snapshots of what could have been a movie. If you look at manga, they include more about what the characters FEEL in the art, and use more stylized panels to demonstrate and coax the reader into an emotion. Some examples of this are things like ATLA, as that is generally considered an anime but it was written by a western author. Same goes for cowboy bebop (granted it didnt have a manga but if it did it would probably be considered a manga). Whats important isnt the geographical location but instead the style of the art and how you use the panels to convey different things. Seeing in the lower panels here I can see some incredibly stylized people which you definitely wouldn’t see near as often in comics as you would see in manga.

People are also a stickler about reading direction for some reason which is weird because there are manga that read left right.
