Cindy calls him silver-tongued (in a sarcastic way) in the episode " Love Potion #976/J" as he finds it hard to express his feelings. It takes him hours to explain things the scientific way and people find his explanations hard to understand and would ask for a shorter and more understandable version of his story instead. However, he does have a few weaknesses one of them is his poor communication skills. Despite his pride and arrogance, he cares for deeply for his friends and his family and does everything he can to help them. Jimmy is quite charming when he least tries to be, such as at the party, that he throws at his parents' absence in the episode "Party at Neutron's". He won't back down from his beliefs and he strongly believes in himself. He enjoys being the hero, often taking a staunch stand against anyone he believes to be evil. Sometimes Jimmy can be unsympathetic to other people's feelings and can come off as a smart-alec or a nerd. Jimmy is shown to be quite irritable around most people, mainly his friends and thinking he's above it all. Jimmy is a very nice guy, although sometimes he can be a bit arrogant and a know-it-all. In the third season, however, he seems to stop Brain Blasting and comes up with ideas right away, with " Fundemonium" being the only episode that season to use the "Brain Blast!" sequence. Jimmy will then shout, "Brain Blast!", and arrive at the solution for whatever danger he has landed himself, his friends, or his town in. In the moment of crisis, he will urge his brain by saying, "Think, think, think!", where upon the camera enters Jimmy's ear and goes into his brain to observe its inner workings as well, as to relive a scene from the early part of the episode. He is usually joined on his adventures and days of mischief by his best friends Carl, Sheen, Goddard, Cindy, Libby and Nick and they serve as a perfect foil to Jimmy and one another. They do put him exciting adventures though and make life more interesting. He designs his wild inventions to help him deal with bothersome chores, but more often they end up causing a bigger problem. This usually leads Jimmy causing accidental trouble to Retroville. This brain, a source of constant comment, allows him to invent devices that accomplish even the impossible.

In many episodes, his classmates are angered, because he is so smart and keeps outdoing them in anything math and science related. Jimmy is a very intelligent kid, having an impossible I.Q.
