Super Mario Klemp-Won-Do: Muskeln sind nicht alles!
Chun-Li and several other characters from the Street Fighter II series appear in the Club Nintendo comic "Super Mario Klemp-Won-Do: Muskeln sind nicht alles!". She is seen laughing along with the others when Mario decides to enter the "Street Fighter II grandmaster" tournament.

After Mario's surprise victory over Zangief, Chun-Li is his next challenger. Mario immediately falls in love with her because of her beauty, unaware of this, and expects a "victory kiss" from her as a reward for winning his last fight. To his surprise, she starts kicking him, forcing Mario to think quickly. He gets the idea to tickle Chun-Li's feet with a feather, causing her to laugh uncontrollably and leaving her unable to battle. Mario wins the fight and advances, facing Blanka in his third match.
