@TheAncientCenturion posted his first good comment in 10 years when he pointed out the Fenrir theory.
Fenrir was imprisoned by a one armed War God with red hair before later being released and killing Odin.
Fenrir= Loki?
War God= Saint Shanks?
Odin= Imu? (At least Imu on Elbaph, maybe Loki will be the one who land the final blow on Guunko Imu)
Powerscaling: Fenrir is more powerful than Odin, the most powerful Norse God, meaning Woki >>>> Saint Shanks is once again reinforced.
