Xiao Xiao () is an Internet Flash cartoon series by Chinese animator Zhu Zhiqiang, featuring stick figures performing choreographed fight scenes. Some of the cartoons are interactive and game-like. All cartoons are in the Adobe Flash format, with the exception of Xiao Xiao #1, which was originally in AVI format and converted to Flash format. "Xiao Xiao" literally is the Chinese character for "small" repeated twice in Mandarin Chinese; here this reduplication connotes an affectionate diminutive, an equivalent might be the English expression "itty bitty" or "lil' old". Each Xiao Xiao cartoon is given a Chinese title with the adjective "Xiao Xiao" preceding a descriptive noun phrase. Xiao Xiao #1 was originally titled "Xiao Xiao Zuo Pin", which translates to "A Little Bit of Creative Work". Since then each Xiao Xiao cartoon has had a different noun succeeding "Xiao Xiao". #4 is titled "Little Sheriff", and #7 is titled "Little Movie". The term has gradually shifted meaning from the cartoons themselves to the main character, an anonymous black stick-figure. In this context it means something akin to "little fella", appropriate since in most perspectives Xiao Xiao and his fellow stick-people appear tiny and childlike, with disproportionately large heads and small limbs. Xiao Xiao is placed in various dangerous situations to prove his martial arts prowess, often against other stick figures who appear more or less identical to himself. Usually other stick figures are also black, but can be other colors, and Xiao Xiao's perpetual nemesis is the Boss, a purple stick figure who commands the enemy sticks and appears to be Xiao Xiao's only peer in ability. Others have seized on Xiao Xiao's popularity to make animations exploiting the easy-to-draw style of stick figures and minimalist backgrounds, often creating cartoons that are sequels or takeoffs of the official Xiao Xiao cartoons, especially Xiao Xiao #3. Episodes Xiao Xiao #1 is a simple fight between two stick-figure men, parodying the look of Hong Kong martial arts films by taking the level of violence in the fight to extremes. Xiao Xiao #2 adds interactivity; the stick-man (Xiao Xiao) faces a series of physical challenges, the outcomes of which depend on the player's timing. The game contains many features that would later become a staple of the Xiao Xiao series, including revamped animation and character design, most notable the introduction of the series' main antagonist, "The Boss" (although he is not referred to
