Ace has the potential to become One Piece, the reason why he did not become one is because the protagonist of the anime is Luffy, and the other reason is that Ace took the initiative to give up his dream of being One Piece. After Ace’s “death” in Sabo, Ace turned One Piece into his second ideal or even the icing on the cake from the bottom of his heart, rather than the first ideal like Luffy. Since childhood, Ace was discriminated against because of the son of One Piece, like Naruto Naruto of Naruto in Naruto, so Ace’s ideal is to become the strongest One Piece and be recognized (at the same time, there is also Oedis who surpassed his irresponsible father. Complex in). But if Ace is not the son of One Piece, Ace will be educated as a navy by Karp with a high probability. After getting to know Luffy Saab, Ace was recognized by his relatives and friends, and his goal became just to become the strongest One Piece. But after Sabo’s “death”, Ace realized the importance of his family’s brothers. He grew up overnight and became an eldest brother. He began to put his younger brother Lu Fei (family) first. Become a gentle, polite, well-mannered elder brother who can take care of others. From this meeting onwards, Ace’s first ideal has become the first in his family (same as White Beard), and becoming the strongest One Piece is just his second ideal when the first ideal is realized. It is the icing on the cake. (Different from Doflamingo’s family concept, Ming values family, but in front of his own ambitions, his family is a fart. For Ace, compared with his family, One Piece is a fart! Although Luffy treats One Piece As the first ideal, but he will never sacrifice his companions like Ming Ge. When in Daughter Island, Lu Fei did not hesitate to choose to save people in the choice of saving people and going to sea). After truly integrating into the Whitebeard Pirates (with his father, Whitebeard, whom he really recognized in his mind), Ace really recognized his ideals, and the so-called second ideal was abandoned by Ace. Ace’s only ideal is family first (Luffy, Karp, Dadan, White Beard Pirates). So after Sabo’s death, Ace gave up his potential to become One Piece. Later, when I talk about being the One Piece, it is more about the commitment between the brothers (the three brothers have made the ideal to be the One Piece) and the pursuit of childhood bonds. The starting point has changed. In terms of panel attributes, Ace does have all the necessary qualities of a hot-blooded anime protagonist, but in terms of personal pursuit, Ace has become the second white beard imperceptibly. Ace caused a big storm shortly after going out to sea, became a supernova, and received an invitation to become Qiwuhai. This salary is slightly worse for Luffy (even if Luffy succeeded in the challenge for Qiwuhai, he never received the invitation to become Qiwuhai. Wu Hai’s invitation.). And on the ground, he fought with Shichibukai at fifty-five percent on land (Although Lufei at the same age challenged Qiwuhai twice, his personal strength did not reach the level of fifty-five.) Plus, he has been overbearing since he was a child. And unlike the master belt of Sabo Youlong, this talent is really the strongest at present (second only to Aunt Kaido). If Ace did not die, even if he became the captain of the Whitebeard Pirates, he would take Whitebeard as his lifelong pursuit instead of becoming the Pirate King.
