I agree with this anon, Ophiuchus might have multiple forms and the mechanical serpent is just the "weak" form and the actually man holding Serpenes(the snake constellation) would be even stronger, like how it went with Pisces, plus he also could have gotten affected by the Eclipse gate too and obtained an Eclipse form.
