gamerant.com:

One of the Yonko in One Piece, Shanks is an incredibly powerful character who also holds tremendous significance to the plot of the series. Shanks was introduced quite early in the story as the man who set Luffy on the path to becoming the Pirate King. Since then, his appearances were rather limited, however, it wasn't long until it was clearly established that Shanks was truly a monster in combat and ranked among the four most powerful pirates in the story.

While Shanks spent most of his time on the sidelines, One Piece entering its final phase means that now is the time for him to enter the fray as well. In the final arc, Shanks is going to be a key character and will make his presence felt. Given that he's a Yonko, every fan of One Piece knows that Shanks is a mighty powerful pirate and his main source of strength is his incredible Conqueror's Haki.

Although Conqueror's Haki is a power that was explained properly by Silvers Rayleigh quite late into the story, shortly before the timeskip, Shanks was the first person in the story to demonstrate its usage. Upon saving Luffy from the Lord of the Coast in the East Blue, Shanks used his Haki to intimidate the beast. Back then, fans had no idea about Shanks' capabilities as a user of Conqueror's Haki, however, it wasn't long until a good display of this power was given to everyone. After the Enies Lobby arc, Shanks met with Whitebeard in the New World and gave the fans a proper demonstration of his Conqueror's Haki, which was certainly quite impressive. The likes of Jozu and Marco were well aware of what he was capable of and the former even commented on this power of his being incredible.
