This is a theory I made up recently while reading the book where Mike dies. I feel that Grisha cannot be the Ape Titan whatsoever, as the Ape Titan is unaware of what the 3DMG is. Since Grisha lived during the time where humans possess the 3DMG, it's nearly impossible for Grisha to become the Ape Titan. My theory of who the Ape Titan could possibly be the very first titan or any kind of Human-Titan person from about 100-75 years before the fall of Wall Maria.
