Odd Della Robbia is a member of the Lyoko Warriors, and one of the two tritagonists of Code Lyoko.

Odd is a blond-haired boy with a purple streak. Originally he wore his hair down, as seen in the prequel. After he was virtualized on Lyoko for the first time, he adapted the spiked up hairstyle of his avatar. According to the French version of Amnesia, he uses an extra strength gel to get it that way, and the script for The Key reveals he applies it while doing a handstand.[1][2]

For the first three seasons, Odd wears a magenta t-shirt underneath his long sleeve purple shirt, full-length trousers with dark shade purple and light shade purple (one shade on either leg), and gold-colored shoes, His night clothes (most likely his underwear) are red and orange . In Season 4, he still has his magenta shirt with a purple long sleeve shirt, but now with a light short-sleeved purple hoodie over both, wide periwinkle-colored cropped trousers-style jeans, and red shoes. In Evolution, his blonde hair is changed to brown. Most of the time, he has different clothes that are not purple.
