Odd Della Robbia is a member of Team Lyoko and possibly the most popular among fans for being kindhearted, carefree and funny. He calls himself a ladies' man, but the females he's dated would say the opposite. He likes the color purple, and wears it on most of his clothes. He is one of the Lyoko Warriors and is Ulrich's best friend.
DescriptionEditOdd like his name, is very odd, and stubborn too. He wears a purple outfit both on Lyoko and on Earth, usually with some pink in it and yellow accompaniments to match his hair, which has a natural purple streak in the middle. His night clothes (most likely his underwear)are red and orange, not purple, and probably due to the fact he did not buy them. He claims in various episodes, such as in Swarming Attack and A Fine Mess, that he knows how the female mind works and that he has a "way" with females. Naturally, he is horribly wrong, getting slapped by not one but two girls in the latter episode., though it was Yumi who was slapped as she and Odd had been switched between their bodies.
Odd's Lyoko outfit is a self described "giant purple cat" complete with a tail and claws (which he can use to climb). Strangely enough, the front of odd's suit has a picture of his dog Kiwi peeing. His forehead and cheeks also have purple markings on them.
Odd is Ulrich's best friend, and shares a dorm with him at Kadic. He is a member of the eighth grade. he doesn't do well but maintains a 75% average. His pictures are very detailed, and puts a lot of work into them. He enjoys folding his tests into paper cranes, which Jim then collects. He knows various fighting techniques like boxing as shown in Franz Hopper (episode) (how he learned them is not made clear), and has the knowledge of the stereotypical prankster, as demonstrated in Satellite when he picks locks to get his cell phone back. He is also good at performing music, as he formed a rock group called Pop Rock Progressives in Seeing is Believing and played the guitar for a play in Laughing Fit. He also does not like biology, as he states in Ghost Channel.
Odd is able to eat large quantities of food, even eating food off the trays of his friends. Ulrich has even commented that he has more than one stomach. Despite his rather large appetite, he maintains his "svelte" body through his metabolism. Because of his high metabolism and sky-high energy levels, many people call him "scrawny"; this is met with the line "I'm not scrawny, I'm svelte!". Although Odd has been able to get dates with many girls, the relationships usually end quickly.  He is very fluent in Italian, probably because his family is from Italy but he is also capable of speaking Japanese and Chinese, as demonstrated in A Fine Mess when he is in Yumi's body.
In Double Take Odd's new outfit is briefly shown when he saves Yumi, he keeps his paws and tail and purple colour but his new outfit includes a set of cat ears and a slightly chromish addition to the design.
In Maiden Voyage his real world outfit is also changed, he now wears a purple hoodie with a pink undershirt and blue-violet jeans.
