Fried from the inside, squashed by magnetic force outside...yeah, that's one way to make the fat lady sing. Fantastic to finally see new DF Awakenings. Kid and Law have special emphasis on their DF-based fighting styles — Luffy taking a break to learn haki from no-DF Rayleigh — it's logical progress for them and flips the script so these Yonko fights aren't all about haki. Doffy's rule was that Awakening affects something other than the user's body, sure enough Law opens a Klein Room (small room) centered around his blade while Kid puts a magnetic field around Big Mom. Gamma Knife used radiation to make a fine incision inside the body, here Law just phases the sword through to send a shock wave inside BM. Kid's power could have massive ramifications depending on the duration: if Big Mom is incapacitated by too much metal for even 5 minutes, that's enough time to defeat the homies and toss that katamari ball off the island.
