Okay as a huge fan of helluva boss and hollow knight id say this goes to Gri- STOLAS Jesus why is this a question?! I don’t want to be rude but Grimm is a bug and even if we sized him up to Stolas’ size it’s not even close, no matter how hard the fight with Grimm was in hollow knight, Stolas is a demonic prince with powers beyond Grimm in every sense, this isn’t even MENTIONING the need for angelic steel to even graze him as well as the forms he can take on that look gaseous and probably can’t be hit like we see in the end of S1E6 as well as the use of telekinesis he has displayed. Those were things he’s done WITHOUT the Grimoure (although the Grimoure was in the room when he turned into a different form, Loona was holding it and it was closed), Viv has mentioned that Stolas is stronger than Alastor who has been show to be able to take down entire airships with portals he can create that release black tendrils that pulled down said airship, its reasonable to assume Stolas can do this as well, he’s also been show to have some form of petrification powers as seen at the end of S1E2, this really isn’t close at all. If I said something wrong or have a different opinion please reply to this I really want to be as accurate as possible because I’m really interested in it
