"Shanks is featless"
-one shot Eustass Shit
-scared Aramid
- defeated Loki (i can't put L as a first letter in the name because already start with L)
.
Shanks' main feat you forget, he stopped Akainu with one hand casually, and somehow prevented Kaido, the strongest creature, from going to the Marineford war. Kaido recognized him in strength since then, in that scene where Kaido compares Luffy with the legends he knew, Shanks is in the center.
But all of Shanks' feats are only positive for Mihawk, because Mihawk is the top 1 in his category while Shanks is the top 2, so if Shanks has n feats in history, we will know that Mihawk will be able to do n+1 feats.
