Fictional characters have referenced what they're from a number of times (i.e. Superman referenced DC, Lewis & Clark referenced Bill & Ted's actors and Bill & Ted seemed to be aware of who they were as well, RoboCop and Terminator referencing the other's movies, etc.), as well as characters generally acknowledging that they're paired up against the other in a rap battle (i.e. Isaac Newton).
