IF Janperson does indeed have a human consciousness, it'll entirely depend on how human-like it is.
Since presumably the first thing he'd do is try to scan and analyze the Adversary with his sensors, for those scans to yield any results, he would already need to have a preconceived notion of what the Adversary is
(The Adversary is a giant muscular demon(?) lady who towers over the Hero, who's
already huge in his own right. I don't know what bio-monsters are, but I assume that's what Janperson would take her as?
)
The Adversary herself will just wait for Janperson to do the first move (
She refuses to fight anyone who isn't fully ready) and
boast about how it's been ages since she’s faced a worthy adversary, and so on. Her passive Subjective Reality will also turn the area (Central Park?) into a
cramped and oppressive space with
the only way out being through her.
If Janperson's consciousness really only just extends to differentiating between "right" and "wrong" and little beyond that, he'll probably pay it no mind and just nuke the Adversary if I had to guess, if not maybe the Adversary has a chance to influence him.
