You'll be using your favorite comic/manga character here. If your character is:
Low/Mid-Street - They need to beat Spider-Man.
High-Street - They need to beat Iron Man.
Mid-Tier - They need to beat N-52 Superman.
High Tier - They need to beat Silver Surfer.
Herald - The need to beat Thanos.
Teambuster - They need to beat Odin.
Skyfather - They need to beat Galactus.
Abstract - They need to beat The Living Tribunal.
You can wank your character as much as you want: PIS, High-end feats, outliers, scaling, ABC logic, you name it. Let's see who can make the funniest argument.
I guess by this list, Iron Fist would be high tier street.
Maybe a bump up on a good day, when he's able to endlessly amp and KO death gods.
