Portgas D. Ace is one of the most important characters in One Piece and an individual that fans have come to love over the years.

In fact, his debut with the power of the Mera Mera no Mi, was proof enough for the fans that he was one of the strongest in the story at the time. However, Ace ended up dying in the Paramount War, where it was made clear to the fans that he wasn’t in the same league as the likes of Akainu, after all. Yet, Ace remains to be one of the most underrated characters in One Piece, and very few individuals even know of the fact that Ace possessed the ability to utilize powerful Haki.

Portgas D. Ace’s Haki Types

How Ace Gained and Improved His Armament Haki

Ace has not used Observation Haki explicitly in One Piece, but what is clear is that he had the ability to utilize Armament Haki to great effect, which is something that hardly anyone knows. Ace awakened the power of Armament Haki during his journey through the Grand Line. Specifically, on the island of Sabaody Archipelago, Ace faced off against Vice Admiral Draw of the Marines. Being a Vice Admiral, Draw had access to Armament Haki and he posed all sorts of problems for Ace, who, at this point, thought being a Logia meant that he could defeat most individuals effortlessly.

Ace’s Potential As A Fighter Was Enormous

Unfortunately, Ace ended up dying in One Piece, but, had he survived, he would have gone on to conquer the era. Ace had tremendous potential, such that Sengoku openly stated that he would go on to become the leader of the new generation and become the next Roger. This would mean that had Ace gotten time to grow into his abilities, he would have attained bounties closer to 5 billion and terrorized the Government in his own way. His potential could be even greater than that of Luffy, and that certainly goes to say a lot.
