Mostly based on his connection with Acheron. His character design alone isn't very Kevin-esque but neither is Acheron and Mei's. Acheron also does drop a couple of subtle references to Izumo Kevin during Penacony hinting at a potentially bigger role further down the line. Mixed that with Hoyo's slop writing style it's not that hard to come to conclusion that it's probably going to be a rehash of Project STIGMA where Zephyro kills billions to save "humanity" in the form of white hole matter against IX.
