I recently came across this bizarre comic book page from All-Star Batman and Robin #9:
(Bizarre because of the writing, not the yellow paint)
Clearly that's not Batman, but I couldn't find a source as to who or what is controlling him. It must have been much further back. It reminds me of when Doctor Octopus
took control of Spider-Man
What happened to Batman in this case? Possession or some other control of him?
