Dijonay May Jones (voiced by Karen Malina White) is Penny Proud's sassy, enthusiastic best friend who knows her best. Dijonay is loyal at heart and is often the first to come to Penny's aid and encourages her other friends to do the same. However, her impulses often overtake her better judgement and will cause her to ditch her friends for instant gratification or to escape trouble. She also cannot resist gossip and has gotten Penny and her friends into trouble many times. Eventually, Penny decided she had to stop trusting Dijonay, though the girls still remain friends. Despite this however, Dijonay has shown major loyalty to Penny and has had her back plenty of times. In return, Penny continues to show Dijonay unconditional love and one of Dijonay's biggest fears is losing her in any way, shape or form.
Dijonay comes from a large family and is the oldest of 10 children. She has a cousin named Bethany.
Dijonay is somewhat chubby and is the shortest of all the girls in her friend group (not including her hair in the measurement). She has dark skin and medium-length dark blonde hair, with the top being tied into a ponytail that sticks up at the top of her head.
In the original series she wears a pink collared blouse that exposes her stomach, a pastel blue cardigan sweater, a medium blue skirt and sneakers with light pink socks, a similar style to Penny's. Her ponytail was held by blue bobbles.
In the revival, Dijonay is a bit taller, her hair is a bit longer and wavier, and she has more noticeable curves. Her shirt is now a v-neck top and completely covers her stomach, and she has a regular blue hair tie.
Dijonay Jones is an completely extroverted individual and wears her attitude on her sleeve. She is loud-mouthed, hyperactive and loves having conversations. Dijonay's love for socialization comes with its flaws however as she is fully nosy and cannot resist gossip. She also has a big mouth and has sold Penny out many times. Dijonay is also completely inconsistent and it can be difficult to decipher what her ultimate goal is. She has been disloyal on many occasions to her friends and is quick to abandon them at difficult times. She mainly does this with Penny and often times LaCienega, who are supposed to be her two closest friends. However, Dijonay has also helped Penny in the clutch and saved her from danger and embarrassment in key situations and has played an important role in helping to integrate Penny and LaCienega during the early part of the series where the two clashed heavily. She also has no problem sticking up for her friends when she feels they are being treated unfairly. Dijonay is very upbeat and can bring energy to an otherwise dull social environment which is fitting since she is captain of the Willie T. Ribbs Racer Cheerleaders.
Despite popular belief, Dijonay is a hard worker and a master of time management. She is often stuck babysitting her nine brothers and sisters, all of which are even more hyper than she is. Years of this has allowed to develop excellent cooking and cleaning skills. Dijonay was once seen cooking Duke Anoi an entire meal on a surfboard with him and she did an excellent job and proved that she could possibly be a good wife in the future. She still manages to find enough time to do her homework, serve her duties as cheerleader captain and hang out with friends. She also manages to squeeze in time for her favorite hobby, writing poems and even learning foreign languages. Dijonay can speak fluent Italian and once had a conversation with Kobe Bryant in front of her friends, leaving them in shock. She's even worked a few jobs during this time as well. Despite this, Dijonay seems to doubt her own abilities, especially her intelligence and unknowingly holds herself back as a result. She's also well aware of her short-comings and seems to accept them.
Despite her selfish-impulsive behaviors, Dijonay is loyal at heart and always comes back to the people she cares about most. For example, she sold Penny out to the Gross Sisters for $5. But once she got the $5 she helped save Penny alongside Sticky Webb. Also, Dijonay has an unhealthy obsession with Sticky and stalks him constantly, often driving him insane. Like Penny, Dijonay's hormones run high and can be really crazy over boys and is the quickest to flirt; however she always returns to Sticky.
Being the youngest of the group, she is often the most immature and Penny, LaCienega and Zoey often find themselves having to talk sense in her.
