Patri excluded, Gadjah is the strongest new arrival here, and even Patri would have a tough time with Gadjah lol.
Imagine that Noelle after all she showed in Vanica fight still told Patry that he is on another level and she needs his help.
Demon Light Magic Patry can potentially solo a Devil right now but we will need to see.
Like it was stated above by some.
Gadjah is easily above all Captains excluding Mereo and Yami.
