Ancient Robot bro, we have no idea how strong it is and if it can hold them all off. If the AK is supposed to be taken seriously, then we'll see how they'll be stalled.
The one thing I doubt however is Luffy not winning one fight here as a Yonko
Nah ancient robot isn't stalling gorosei by itself
You're having too much faith
Forget about Kizaru
Did you see even in this chapter Kizaru can't do crap!
Why are you so stuck on this?
Kizaru can't give Luffy an extreme or very high diff battle
Everytime he gets dominated by Luffy
He literally clashed Luffy this chapter and couldn't do a thing despite having Saturn help
