This page explains in detail the interactions between the Adventure Quiz series and the Street Fighter series.
Adventure Quiz: Capcom World 2[]
June 11, 1992
Adventure Quiz: Capcom World 2 features several Capcom characters appearing as the player engages in the game's many quizzes, being the ones challenging the player and presenting the questions. The 8 playable characters from Street Fighter II: The World Warriors all appear among the cast.
The first area in the Expert Course (named "Final Voyage") is set on a harbor that greatly resembles Ken's stage from Street Fighter II, including a yatch very similar to the one seen in the version of the stage from Super Street Fighter II: The New Challengers. The music theme in this area is a remix of Ken's stage theme as well.
Chun-li makes two minor extra cameos: one inside the yatch in the area described above, and another in a 2-player game, where a chibi-styled Chun-li comes with two big flags at the end of a quiz session and waves the one flag in the direction of the player with the most correct answers.
Street Fighter Alpha 2[]
February 27, 1996
Ken's stage in Street Fighter Alpha 2, titled "San Francisco Bay", is set within a cruiser of his ownership where he's holding a birthday party for his girlfriend (and future wife) Eliza. This stage features several character cameos from an assortment of Capcom's franchises, appearing as guests of the party and visible in the background tending to themselves as the battle unfolds.
Pure the Mage from Adventure Quiz: Capcom World 2 appears among the party guests. She can be spotted on the right side of the stage, sitting on the edge of a large pool. She sports a green one-piece bikini, but keeps her regular costume's green hat to make her recognizable.
