Whenever Ricky manifests the vestiges powers, he gains access to their signature move, and their abilities. And Greninja's manifested just after Ricky evolved which was how Ricky was able to access the Bond phenomenon with Izuku.

Whenever Ricky and Izuku activate the bond phenomenon, the vestige worlds temporarily merge allowing them both to use the same exact quirks/moves
