I feel like a lot of people sleep on Killer because he hasn’t shown any feats yet.

But, I’m predicting that he and Zoro are gonna have a reluctant team-up this arc because in a way, they are so similar to each other that I felt Oda did it on purpose ever since he designed the Supernovas back in Sabaody.

1-Killer and Zoro are the only 2 non-captain Supernovas of the Worst Generation.

2-Killer and Zoro are also recognized as the “right-hand man” of the Kid Pirates and Straw Hat Pirates. Similarily, they are the first members of their respective crew besides their captains since Killer & Kid are both childhood friends and founded the Kid Pirates together and Zoro was the first member Luffy recruited.

3-They’re also the only ones of the 11 Supernovas that don’t have a Devil Fruit

4-Their whole fighting style revolves around blades. Sure Basil Hawkins and X Drake use swords but those two seem to use their blades as afterthoughts or combine it with their devil fruits. Killer and Zoro’s whole strength comes from their blades since they lack devil fruits.

Killer really feels like Zoro’s counterpart similar to how Kid and Luffy are counterparts. And in a arc like Wano where swords and blades are abundant, Killer’s strength is gonna shine well here.
