I guess it will go something like this:
>Knowing the SHs, a yonko crew, are too strong to defeat, Lucci will activate a special type of buster call that only the celestial dragons and CP0 have access to.
>This special buster call summons 3 admirals in addition to a massive fleet of VAs.
>Lucci will then stall in order for the admirals to arrive.
>Lucci and Kaku can become invisible by moving fast, like sanji. However they have mastered this technique; due to being awakened zoans, they don’t tire when using it. They also developed a technique to hide from CoO.
>Ultimately, Luffy beats Lucci and Kaku by using G5 to access invisible speed, allowing Luffy to catch up to the two, who were otherwise trying to avoid him.
>admirals come, however, Kuma appears just in time to save them. Kuma uses his powers to send the Sunny flying, saving the SHs, Bonney, and Vegapunk.
>Kuma sends the sunny to elbaf.
