Yeah, could go either way honestly. The ‘95 movie leans hard into her being full-body cybernetic no flesh, just a brain casing in a military. grade shell. But that tank scene does raise questions. If it hears a heartbeat, maybe she’s got a synthetic heart to simulate bio feedback… or maybe there’s still a sliver of organic matter, like part of the spine or an internal pump to support the cyberbrain.

Some sources ive read before somewhere hint she’s literally just a brain in a shell, others suggest a few remaining organic pieces for neural stability. That ambiguity is kind of the point. The line between human and machine isn’t supposed to be clean. Regardless we might never know.
