Books for a 14 year old meat head with ADHD?

I have a 14 year son with ADHD who only ever read Captain Underpants and Dog Man books… he loved the Bad Guys series. He’s kind of a “too cool for school” jock who’s secretly a nerd… I’m trying to foster the inner nerd.

I’m looking for book or graphic novel recommendations that might catch and keep his attention. With such a short attention span, I’m concerned a traditional novel will lose him.

As far as interests… he loves the Five Nights At Freddy’s games and fan fiction spin offs. Loves baseball and animals. I’d be okay with something a little more adult but maybe lighter on the sexy stuff.

I wasn’t much of a reader when I was a kid… when I did read it was more almanac-y style stuff that I could pick up for 3 minutes or an hour and geek out over some subject.

Thanks!
