Probably fake but Oda could do something like this:
Chapter Title: That Day on Elbaf
~ It is revealed that Zoro saw this reaper during his training days. The reaper allowed him to live at the cost of his left eye. Zoro believes the reaper wants his life the minute the serum wears off.
~ Franky is carrying Zoro as the reaper follows them. Franky can't see it but he runs away upon Zoro's orders. (he thinks Zoro is insane). Zoro tells Franky he'll probably die so he wants him to take him to "that" place before he does.
~ Franky explains Zoro's situation to Chopper on den den mushi as they run toward a particular location. Chopper warns Zoro not to go but he knows Zoro won't listen. He changes to leg point and begins running towards zoro's final destination. "Even if there's a **1%** chance I can save him, I'll save him.

~ Kidd punches through Napolean shattering the blade and sending her flying high above Onigashima.
~ Law dismembers Big Mom into multiple pieces as she drops back down.
