Timeskip Strawhats Vs Spartoi
-No holding back
-All serious and bloodlusted
-Win by death
The Spartoi are straight up outnumbered and outmatched in overall physical capabilities; such as speed, durability, and dc. Especially when it comes to the monster trio, whom also have precog to further augment their speed. Robin could just start breaking all there backs as well, but maybe expect for BS, who would be the only serious threat from the Spartoi with his speed, soul attacks, and the fact he uses a sword. In the end, the Spartoi get stomped.
The weaker Strawhats vs the Spartoi (excluding BS, Kid) would be a better battle IMO, with the Spartoi most likely coming out on top.
After decades the 'blackout' rule may be coming to an end.
