Nefertari Vivi has become one of the most important characters in the One Piece story. Her role can be seen from how she is being targeted by Im Sama as one of the main characters to be eliminated. Im Sama is currently after Nefertari Vivi after her father was killed by the ruler of the One Piece world. Im Sama considers Nefertari Vivi as one of the people who has the potential to disrupt his rule.
This is not unrelated to Nefertari Vivi’s status as a descendant of Nefertari Lili, who was a traitor to the world government led by Im Sama. As a descendant of Nefertari Lili, Nefertari Vivi is said to have the same appearance as her predecessor. Not only that, Nefertari Vivi also inherited the privilege from Queen Alabasta 800 years ago. That privilege is able to control the ancient weapon Uranus and hold the key to activate pluton. That is why Im Sama is so eager to capture Nefertari Vivi.
However, despite being one of the most important characters now, Eiichiro Oda apparently has no plans to make Nefertari Vivi an important character. What is happening to Nefertari Vivi now is something that is happening outside of the scenario of Eiichiro Oda. This was revealed after Eiichiro Oda revealed it in an interview. According to Eiichiro Oda, Nefertari Vivi was designed to be just one of the Baroque Works agents, nothing more than that.
But Eiichiro Oda’s mischievousness when drawing Nefertari Vivi with flowing hair opened the way for the princess of Alabasta to become an important character. Eiichiro Oda thought that when drawing Nefertari Vivi with flowing hair, the character looked very much like the princess of a kingdom. This idea made Eiichiro Oda truly turn Nefertari Vivi into a princess when starting to work on the Alabasta arc. And who would have thought, Alabasta turned out to play an important role in the One Piece story.
Nefertari Vivi herself is believed to soon rejoin the Straw Hat Pirates. Given her current situation of needing extra protection after becoming a target of Im Sama. Despite being originally designed as just one of the Baroque Works agents, Nefertari Vivi has become an important and valuable character in the story of One Piece.
