The Manga One Piece Concludes the Egghead Arc as Luffy and the Crew Head Towards Their Next Destination, Elbaf.
However, this event in One Piece wraps up with Imu confronting the Celestial Dragon, Saint Jaygarcia Saturn. To maintain the balance of power among the highest authorities in the world, Saint Figarland Garling has been appointed to replace the former Celestial Dragon who has vanished.

Garling has some connections with Red-Haired Shanks, one of the most notorious pirates in the world. However, while the story hasn’t yet clarified the relationship between these two characters, a fan theory circulating in the community suggests that Garling might oppose the World Government.
One Piece Often Introduces New Characters to Make the Story More Engaging, Including Figures Like Viola, Kanjuro, and York. Garling is a Celestial Dragon and the Commander of the Holy Knights, and he is also the first character introduced in this new military faction.

With the authority of the Holy Knights, Figarland Garling holds tremendous power over the remaining members of this military group. Moreover, Garling may even have the final say regarding other Celestial Dragons. This indicates that, although they are all Celestial Dragons, Garling’s status, role, and privileges are significantly higher than those of the remaining members.
Thus, the presence of this character opposing those who have long held power is likely to be one of the most shocking plot twists in the series.
According to the translator Sandman, “Figarland Garling may be based on Yuri Gagarin, the first human in space. It is said that Gagarin once remarked, ‘I don’t see God up here.’ This could imply that Figarland Garling will oppose Imu or another Celestial Dragon in the future.”
A prominent fan noted: “Galing = Galileo Galilei. Galileo was the first to conduct detailed observations and scientific studies of the Moon through a telescope. He also observed the stars of the Milky Way.”
