I... don't see Batista as a mad scientist/psychologist

Maybe one of Hugo's henchman

I bet he could pull off the look decently at least
give him a pair of those hilariously undersized round glasses like he wore in Blade Runner 2049 but shinier

give him a big labcoat and he'd roll with it

also look at his performance in Knock at the Cabin
he's still a huge man but look how he shrinks himself with his posture
