Grodd tells them he needs their help to stop Solovar (voiced by Keith David), the leader of Gorilla City, as Solovar wants to invade Earth-1.
As they trek through the forest, Barry and the team are immediately captured and brought to Grodd (voiced by David Sobolov).
Meanwhile, back on Earth-1, Jesse and Kid Flash (Keiynan Lonsdale) hit the streets to stop a metahuman that can control gravity, with H.R. and Joe (Jesse L. Martin) guiding them from S.T.A.
As we learned from Barry’s future vision, this war on the planet with the apes will have a hand in Iris’ fate, but will The Flash succeed in its ape adventure?
