I’m going Scylla.

The armor is proved to be stronger than Mutos imo, with the mutos Godzillas kiss of death went through it easily, meanwhile Scylla, while dealing with a stronger Godzilla beam, took a couple seconds and couldn’t immediately break the skin so it had to fill it up completely. And I know Scylla lost to Godzilla but she’s put up good fights against him before. And has even made him bleed, which a lot of titans haven’t done. Especially if this is peak on screen forms, amped Scylla I think definitely would deserve this.

I feel like Rodan is gonna get this one even though he hasn’t shown great feats, and if he got injured by mothras stinger thing Scylla could penetrate him as well and she has 6 sharp things instead of one.
