Jim and Tim Possible are the younger twin brothers of Kim Possible. They are named after their father's first and middle names, James & Timothy. Although identical, theyve never played the switcheroo trick on anyone. Jim always wears green-themed outfits, and Tim always wears red.They are 4 years younger than Kim. Their mother, Dr. Ann Possible, was pregnant with them when Kim first started pre-kindergarten. When Kim becomes a senior (12th grade), they were scheduled to be 8th graders. But because they displayed a level of genius, they were both bumped up to 9th grade a year ahead of schedule, sharing a year at the same school with Kim.The twins are very intelligent, which gets them into quite a bit of trouble. Theyve invented remote-controlled rockets, fighting robots, silicon phase disruptors, and various computer programs which have wrecked much havoc at the Possible household. They also torture their older sister quite a bit, earning the nickname tweebs, a portmanteau of the words twins and dweebs. In a few of Kims adventures, Jim and Tim have come through to help Kim defeat her nemesis: they use their portable silicon phase disruptor to stop Dr. Drakken's use of mind-control chips on Kim and Shego, they figure out the hows and whys of Camille Leon's one-woman crime wave, they trick Warmonga to leave the Earth (temporarily, at least).Once in high school, they continued to annoy Kim on a new level. They were enrolled in her senior-level statistics class, where they displayed better math skills than their sister. They also became lunch-buddies with Kim's fellow cheerleader (and personal nemesis) Bonnie Rockwaller, telling her various embarrassing family stories. But when it comes around to whether the twins should attend a different high school, Kim says that they helped her when it mattered, so shell do the same, and the boys continued to attend Middleton High.When Kim's boyfriend, Ron, became the star running back for the football team, he retired from the cheer squad, where he was The Mad Dog. Jim and Tim took this opportunity to try out, and they became The Pep Puppies. This irritated Ron for a while, until he realized that 1) they were good, and 2) they were rooting for him. After this realization, Ron, Jim, and Tim use one of the Pep Puppies costumes to fool Warmonga into leaving Earth.The twins have a secret language of their own, the extent of which seems to be the phrases hick-a-bick-a-boo and hoo-sha, or variations of those. But they are able to communicate quite a bit in those few words. Show less «
