What is the final form of the rubber fruit?

In episode 1044 of "One Piece", Luffy awakened his Nika form.

In this episode, Luffy successfully awakened the fruit's ability and developed his own fruit's true form, Nika form. This is the powerful sun god Nika form, and Luffy also successfully obtained it. After reaching the fifth level, he successfully defeated the powerful Yonko Kaido and became one of the new four emperors.

The final form of the rubber fruit is the fifth-level Nika form. Except for the Five Old Stars, few people know this secret. The real name of the rubber fruit is the Nika form of the phantom beast species of the Renren Fruit. The Five Old Stars changed the name of this devil fruit. We speculate that Joeyboy had the rubber fruit ability eight hundred years ago. This devil fruit has some kind of consciousness and can avoid the search of the world government. In the past eight hundred years, the rubber fruit has transformed from a god-level fruit into an ordinary devil fruit.
