Apoo reacted to both Zoro and Drake (aka the two who defeated him)
To Zoro (who was attacking Saint Charloss with Ittoryu) in chapter 499 mentioning a killing intent that returns in chapter 995 when he is chased by all the Live Floor (which makes me think that Apoo specializes in CoO)
Same goes for Drake (who was attacking a Pacifista with his full Zoan form) in chapter 509
We all know what happened in chapters 997 and 998
Just some details that were possibly considered by Oda
