So one thing I gotta bring up, and I'm not sure how much it matters, but Oda has only called the "Vs" matchups for certain pairings. It's interesting:
Killer vs Hawkins:
Kid/Law vs Big Mom:
With this you can very clearly see that Oda has painted a "Vs" matchup with these 2 fights. However, what I find odd is that beyond this, Raizo, Neko and Inu do not get the same treatment.
Raizo both last chapter and this chapter did not receive the Vs title block with Fukurokuju:
* lol he also fucked up the floor Raizo/Fukurokuju were on the first chapter. It's supposed to be the 2nd.
Neko started fighting Peros last chapter so no Vs block could be made, but this chapter had the scene transition back with no Vs block:
Same with Inu, no Vs block this chapter:
And before people say "why not Zoro and Sanji then?", it's important to mention that:
1022: their fights were never set up until the end
1023: their scenes were never transitioned away from the last chapter
The way the Vs titles get used are when we transition back to a fight that's already set up. Fun fact, Yamato never had this with Kaido. But the opposite of that, the F6 did not receive these title cards, outside Jinbe and Robin getting vs titles in the chapter titles.
So IF this means something. We will see once Oda decides to return to Zoro and Sanji's fights. Will they receive VS cards? Do the VS cards mean something? They usually do in other arcs but only started last chapter with Hawkins and Big Mom. Are these Fuku, Peros and Jack's definitive fights? They seem like they are but it's interesting Oda didn't use title cards here while he did for the others.
