Mori Jin
Jin’s powers/scaling at different points have a lot of parallels to different characters in the MCU:
Match with Gods/National Competition Jin is a depowered god with martial arts that are considered to surpass all others and let him fight evenly with beings who are drawing power from extra dimensional supernatural beings and amplify his stats to a great degree. So 9-B (off depowered Thor), 9-A with Re-Taekwondo (Off Iron Fist)
Adventure Arc Jin can take on gods and mythical creatures in base (but not the absurdly strong ones), in Monkey King mode he’s set to become one of the most powerful gods in the universe, but lacks full access to and understanding of his powers. Base would be 8-A (scaling above most Asgardian, Frost Giant and Dark Elf warriors), Monkey King mode should be 7-A (due to similarities ti pre-awakening Thor).
World Competition Arc Monkey King Jin has fully awakened and is in the process of reclaiming power surpassing the strongest gods in existence, so somewhere between 7-A and 6-C, between pre and post awakening Thor.
Ragnarok Arc and Supreme God Jin can easily defeat even the most powerful beings in divine pantheons, and goes on to defeat then become the most powerful of the gods, so he’d be above the likes of Odin, Surtr, and Hela.
Depending on which part of GoH he’s taken from, his ties to East Asian martial arts and mythology could tie him into Iron Fist, or some future phase 4+ movie that either expands on what Shang Chi started, or introduces Thor to a broader mythological cast.
