Vegapunk needs to first hack the dome
Lucci can show them down as a double agent
Blackbeard pirates can slow them down
Seraphim can be released
There’s zero chance the straw hats escape before Kizaru defeats Sentomaru with all those enemies
Well:
- Hack the dome is possibly done even in this chapter to prove Stella is superior to any Satelite.
- Lucci and Kaku can bring Kizaru some time to get there but Luffy, Zoro, Sanji and Jinbe can beat them in no much time.
- Blackbeard pirates seems to be waiting for something, like the aftermath of all of this conflict to gain their prize, like always. Do not think about them colliding directly to the WG or the Strawhats.
