What role does the individual who rescued Princess Vivi play in One Piece?
Chapter 1074 of One Piece manga reveals Vivi's whereabouts with Morgans and Wapol (who's also hiding with Morgans due to government pursuit). They are aboard the World Economic Journal's ship, location unspecified (this ship flies in the sky).
So, who exactly is Morgans and what are his capabilities?

According to the information disclosed, Morgans' alias is 'Big News Morgans.' He's one of the underworld bosses, also serving as the chief editor of the World Economic Journal. This is the primary media outlet in the One Piece world, with all news being edited by Morgans. He has the authority to decide which news gets published and which doesn't.
For instance, Admiral Akainu of the Navy Fleet was both furious and concerned when Morgans declared that Luffy would become one of the Five Emperors in the New World. This merely demonstrates the immense influence wielded by Morgans.
With this role, Morgans becomes a highly influential character in One Piece.
Since his first appearance in the Cake Island arc, Morgans has left a special impression on the audience, especially after the recent incident at Mary Geoise.
Not only does Morgans have a vast influence, but his power is also formidable. This man even defeated a Cipher Pol agent sent to assassinate him within seconds.

Furthermore, Morgans impresses with his appearance resembling a hybrid between a human and a large, tall Albatross bird with a long beak and small eyes. He has wings similar to human arms and a long tail. It turns out Morgans has consumed a 'rare' Devil Fruit called Tori Tori no Mi, Model: Albatross, allowing him to transform into a large seabird.

Morgans is expected to play a significant role in the One Piece storyline in the future. Fans speculate that this chief editor will assist the Straw Hat pirates, as they are close allies of Princess Vivi from the Alabasta Kingdom, given Morgans is currently providing refuge to Vivi on his flying ship.
Fans have speculated that Morgans will play a crucial role in setting up the Elbaf arc. Even his connection to the events at Mary Geoise, Princess Vivi, and King Wapol is highly noteworthy.
