The Qliphoth Likely Juiced It Up A Bit To Be More Equal With Dante's SDT's Level Of Power - Tumblr Posts
I actually do think that Vergil's devil form in Devil May Cry 5 being an inferior imitation of Dante's Sin Devil Trigger makes sense.
While Vergil doesn't have a self-named devil sword like Dante does, it can be assumed that consuming the Qliphoth fruit gave him a comparable (but still inferior) power boost. And as a friend reminded me, demons are speculated to evolve based on what they desire, and one of the things Vergil wants most is to compete with Dante.
I just wish it actually looked like an inferior imitation of Dante's devil trigger. Because Vergil having what is, by all appearances, a canonical Sin Devil Trigger that doesn't play like a Sin Devil Trigger really bothers me. I think it should have looked more unique, like a standard Devil Trigger trying to disguise itself as something more.
Maybe he has a humanoid face, like Dante's standard devil trigger, but he's missing his eyelids, nose, and lips to give a somewhat skull-like appearance.
Since this "Psuedo-Trigger" is likely the result of the Qliphoth fruit, perhaps his body is covered in roots much like Urizen's was, to imitate the scales on Dante's Sin Devil Trigger. If not roots, maybe something with a more ghostly aesthetic, suggesting that his apparently equivalent power to Dante is an illusion. I'm reminded of the armor on Dante's Dreadnought form from Devil May Cry 4.
