According to a tweet from a Japanese commentator on Twitter/X: “From the perspective of the Japanese, the voice of the Iron Giant not only sounds robotic, but actually quite childlike and gentle. From this perspective, it’s as if he is echoing Joy Boy, reminding us of the relationship between Luffy and Shanks.”
The commentator also shared a video, suggesting that the way the Iron Giant speaks is not only reminiscent of a child but also resembles the Sea Kings. Although it is unclear how the robot feels emotionally, every connection he shares with Joy Boy is extremely meaningful.
Shanks is one of the most significant characters in the series, not only due to his future role but also because of his influence on Luffy. He has taught Luffy many important lessons that have shaped the narrative. Luffy has also idolized Shanks since he was young and aspires to become a captain like him.
Joy Boy is also an important figure in the lore of the series. Considering Emeth as a kind of counterpart, he has long echoed Joy Boy since the days of the War of Liberation. The Iron Giant apologizing to Joy Boy indicates that the robot has made him feel a sense of loss in the past.
Even now, the robot still feels regret. Furthermore, Chapter 1119 reveals that Joy Boy has referred to the robot as Emeth and warns him about what he should do when the time comes. Although this chapter does not delve deeply into the robot’s past, it is clear that Emeth’s actions are solely because of Joy Boy.
