I've got some ideas for new Metroid games in a vague sense. While I don't expect Ridley to instantly talk English in the "traditional sense", I do think a cybernetic implant embedded in his skull can produce an evil voice sourced by Michael Ironside . Disregarding the silent nature of the games made before Other M, I think he didn't speak for the audience in the latter because he lacked that implant, not because he was feral. I think the Zebesians acted like animals because of the way they were bred and conditioned for easy control on the BOTTLE SHIP, while Ridley showed signs of intelligence because his cells were conditioned to house his entire memory bank. Kind of like Dragon Ball's Cell character, except his healing factor works differently.
