by name until Xiao Xiao #3), a magenta-colored crime boss who acts as the final challenge of the game via a boss fight. Xiao Xiao #3 is a kung-fu style fight scene in a simple line-drawn building; Xiao Xiao faces off against a seemingly endless series of stick-man opponents (actually around forty enemies) using fast-paced martial arts moves; the simple background, two-dimensional movement, vanishing corpses and regenerating enemies call to mind side-scrolling games. The encounter ends in a final showdown between Xiao Xiao and a purple stick-man labeled "Boss" (another video game reference) in a fight that parodies multiple scenes from The Matrix (especially Xiao Xiao's last move, a slow-motion air kick which resembles that of Trinity at the beginning of the movie as well as using a sound clip straight from the movie).

Xiao Xiao #5, billed as a "Battle to the death... and beyond", returns to the two-dimensional fighting-game-reminiscent side-view style of #3. This time, Xiao Xiao and the Boss duel using various conventions from anime and manga, exhibiting supernatural powers such as the use of magic spells, the ability to pull weapons out of hammerspace and to continue their battle through astral travel after death. It is notable for its comedic ending, where an ambulance shows up in the middle of the fight, taking the two characters' dead bodies away. The two look at one another, then both run after the ambulance. Xiao Xiao #6 returns to Xiao Xiao #2's style, but this time with a bit more of a plot, forcing the player to button-mash Xiao-Xiao through a barroom brawl. Xiao Xiao #7 and #8 are the most
