Why do you think Oda is showing off Loki before people like Shanks, Dragon, Blackbeard, Mihawk?
You think we are not at the end and we already saw the strongest people?
Whether Shanks defeated him or not is not my point, my point is Shanks is stronger than Loki.
Dude is a punching bag that cannot avoid anything, not surprising that he is getting bodied left and right.
We can do a bet about who is stronger, anytime.
