I know 99% of your posts are troll and garbage, but c'mon.
Nika is the first Sun God.
JoyBoy is the one who awakened Nika's fruit first.
Luffy is the one who inherited JoyBoy's will and awakened Nika's fruit.
Luffy is the grand sum of both Nika and JB, at once surpassing both. Luffy was not erased from the manga. His character is being written in a worse way than before, I'd grant you that, but it won't be neither JB nor Nika the one who finds the OP, topples the WG, and liberates the world from the cosmic evil that is BB -- it'll be Luffy, and him alone.
