What are some comics that are good for younger readers?

My little brother is turning 10 this week, and I was hoping to get him some comics. I know a little about comics, but I don’t really read ones that I think would be good for him. I want to know of comics which aren’t designed for young children, but still aren’t inappropriate for kids his age. He’s at the age where he thinks he’s a big kid, so I want this gift to reflect that. Any ideas?
