Blanka (ブランカ Buranka?) first appearance in the Street Fighter series was in Street Fighter II. In his Street Fighter II ending, he reunites with his mother Samantha, who recognizes him from the anklets he wears. She reveals that Blanka was once known as Jimmy, before he was in a plane crash as a little boy. This crash caused him to be raised in the wild, although he has connections to a local village. Ever since the crash, Blanka/Jimmy had been separated from his mother. Blanka's most apparent characteristic is his green color. His in-game storyline states that he was once extremely pale and was once known locally as the homem branco (white man) and adapted the branco into his name Blanka. His green skin color in the games is attributed to his constant use of chlorophyll from plants to better blend in with the jungle environment, a color change that eventually became permanent.
His coloring changed in later games, making him bright green with vivid orange hair as opposed to the yellowish green skin he had in Street Fighter II. Blanka's style of fighting in the games is a self-taught savage fighting style; however, the English language manual of Street Fighter II for the Super Nintendo listed Blanka's fighting style as capoeira. While Blanka's in-game vocalizations are exclusively limited to feral yells and growls, some iterations of the series feature post-fight screens that depict Blanka declaring victory using actual words. Most of Blanka's special moves have Blanka rolling himself into a ball and launching himself at his opponent. There are different variants to this attack (wherein Blanka travels straight forward, upward, along the ground, or in an arc). Blanka's super move, introduced in Super Turbo, is called Ground Shave Rolling, and this resembles the Sonic Spin Attack. In Street Fighter EX2 and Street Fighter IV he has an electrified version of this move. However, Blanka's signature attack is his "Electricity" move. Blanka crouches down and emits an electrical current from his body that shocks his opponent, should they touch him while it is active. He also gains a sliding punch in later games that can pass under projectile attacks.
