Iris' nephew Wally develops super speed similar to Barry's (some version of a new origin would be done here, I don't want him to just have the "stages the same accident as Barry" origin). So Flash takes him under his wing as Kid Flash. Gorilla Grodd comes to Central City demanding Barry surrender himself to him. Barry is (soundly) defeated by Grodd, and taken back to Gorilla City. Wally, now without his mentor, is forced to team up with Captain Cold and Heatwave to go rescue his mentor. Grodd tells Barry he wants his Speed Force as Grodd is dying and believes it can save him (he also thinks it is his birthright). Wally, Snart and Rory get to Gorilla City, rescue Barry and escape Grodd. They are helped by Congorilla and others sparking a revolution in the City. At some point in the movie Iris and Barry start dating. We see all the DC apes in this; Grodd, Congorilla, Silverback, Ultra-Humanite, Primeape and Solovar. [Plot by u/shablam96 on Reddit]
