So I just read the chapter and I found out that bonney is the second nika. Like Im shocked but really happy. I've always like bonney as a character, and she is finally using her full potential.
Her fruit allows her to see alternate futures and pull from it. That’s what distorted future is. She pulled from a future where she had the Nila fruit. as long as she can envision it she can do it hence why she turned giant, and became Nika
