Speed is equalized, both are 7-B, Thanos has his Double-Bladed Helicopter Sword, and Gelatin has his Acid Spitballs, 20 Freeze Juice Syringes, and 10 forks. Battle is in a grass field on a sunny weather, and both are 10 meters apart.
Thanos upscales far above 9.63 Megatons, and the gap between 79 Megatons and 9.63 Megatons is 8.2x given the small margin above one-shot territory that gap is (As well as 7.5x just being a loose suggestion) and how much Thanos upscales, He probably doesn’t get one-shot
Let's make some MCU matches where they horribly lose to pathetic characters so we can mock the MCU forever!!!!! (BFDI objects, characters from PS2 games, tier 8's, tier 9's, you name it!!!! Let's make the MCU SO irrelevant they become the Gumball of the VSBW!!!!)
(On second thought, actually, no, take my comment back, we don't want a repeat of LAST time when we gave a character a shit ton of losses, still create MCU spite memes though)
