Who is smarter Jimmy Neutron or AJ from Fairly Odd Parents?

Answer 1

Jimmy Neutron is a Boy Genius after all. I understand that he has the ugliest hairstyle, but Dexter is a stupid and worthless short guy and his animation is based only on 2-D imaging, rather thant Jimmy Neutron's 3-D imaging. I watched one episode as a kid and I absolutely hate the show Dexter. Although the new HBO show, Dexter is pretty good.

Answer 2

Although both are smart. Jimmy Neutron by far! He's cloned himself like AJ but he builds rockets in his backyard!
