Iron Man: Armored Adventures (2008) is about a teenaged Tony Stark. It is one of the best superhero cartoons I have seen from Marvel, because it gives the characters distinct personalities and lets you get to know them. This expires from Netflix on June 29.
Beating the bad guys is just part of the superhero gig. With a little help from his new, by-the-book rookie partner, Ben explores the quirkier side of things in the alien underground and discovers enemies from his past looking for a re-match, all while a mysterious hunter is hot on his trail!
