I like the idea of exploring Marco's fruit further but for the love of god PLEASE don't suggest things like bringing WB or Ace back lol.
I'm already living in fear at the thought that Oda might end up ruining WB in the GV flashbacks, I don't need further anxiety in my life.
Plus IMO awakening should give Marco more offense, resurrection is already Brooke's thing anyways.
And Pineapple is already too laidback for me to see him being capable of awakening, not that it couldn't happen though.
