The question that many readers are pondering after Kaido's statement on the importance of Haki in One Piece chapter 1047.
In the latest chapter of One Piece

Is Marine Hero Garp endowed with Conqueror's Haki similar to his grandson Luffy? As of now, Luffy's grandfather is introduced as having Armament Haki, but Conqueror's Haki is yet to be confirmed. The concern is whether, with Armament Haki and pure physical strength, Garp has what it takes to be the main rival of Pirate King Roger.
First, we need to understand the significance of Conqueror's Haki in high-stakes battles. We know that characters like Shanks, Kaido, and Big Mom all possess Conqueror's Haki. In the Wano arc, Big Mom defeated Ulti, a Tobi Roppo with high regenerative abilities due to an Ancient Zoan fruit, with just one strike combining Armament Haki and Conqueror's Haki. Kaido himself taught Luffy that Conqueror's Haki, when combined with a powerful attack, has tremendous strength.

Currently, Garp's son is Dragon, and his grandson is Luffy, both confirmed to possess Conqueror's Haki. Therefore, it wouldn't be surprising if Garp also possesses this power. It would be a necessary strength, explaining why Garp could become a formidable opponent to Pirate King Roger and together defeat the Rocks Pirates.
Certainly, Oda is a master storyteller who always knows how to create surprises. Who knows, when we think that Garp, like his son and grandson, possesses Conqueror's Haki, the author may take a different turn. If Garp lacks Conqueror's Haki but remains a character worthy of Pirate King with pure physical strength and Armament Haki, then the Marine hero is truly a master of Armament Haki or he has a new form of power for himself.

Above are the subjective opinions of the article's author regarding whether Garp also possesses Conqueror's Haki like Luffy and other prominent characters in One Piece. What do you think about this? Feel free to share your thoughts!
