The Modern Four

The Modern Four is a crossover between Meet the Robinsons, The Incredibles, Bolt, and Big Hero 6.  Though it is a fairly new crossover, it is gaining growing attention in the RotBTD fandom. In this crossover, the main characters are Wilbur Robinson, Violet Parr, Penny Forrester and Hiro Hamada (in some cases, Tip from Home and Vanellope from Wreck-it Ralph are added in as well).

About the EU
The exact origins of this EU are unknown, but all of the characters used in the crossover have been side characters in the RotBTD fandom for a long time (Especially Wilbur and Violet). Since all the characters from modern times, and with the popularity of pairings such as Willet and Hirenny, many fans decided to put them together in a crossover.Since it is not canon, ideas for this crossover are shown through fanart, videos, and fanfiction.

Since the possibility of time travel in this universe is canon through Wilbur's time machine, it is possible that he could bring many of the crossover characters in the RotBTD universe from different time periods together.
