I hated it after what happened to them and their amazing cover story. Just felt forced and for fanservice. Lucci and co should have gone under Kaido. And thus no need for stupid Who's Who nonsense.
CP0 has been such an overwhelming letdown in many ways.
Oda even admitted he didn't intend to bring back any of cp9 except lucci and kaku for cp0 but since toei brought back kalifa and blueno in Film Red as cp0 agents, oda was annoyed and forced to bring them back in cp0 canonically as well.
I love the cp9, one of my favourite factions and thus group of villains in one piece and their cover story turned them into anti heroes and gave them a bit of redemption and nuance, as they were betrayed and hunted by the WG and framed by them. They saved innocent people's lives from pirate attacks (candy pirate crew I think) and were doing circus shows, which showed another wonderfully funny and goofy side to them, as well as humanising them surprisingly.
Bringing lucci and kaku back like this with awakenings was kind of insulting, especially kaido and big mom had no awakening and nor any beast pirates but these 2 pre TS villains got it?!
Kakus awakening wasn't even relevant, he should have had a rematch with zoro and zoro being wise to his fighting style and vice versa but kakus awakening making him the reason Zoro gets stalled and can't easily just win and put him down, one shot him like the impel down awakened guards.
Jinbei should have faced lucci as who's who was "luccis rival" and lucci being obviously superior especially with awakening no, could have given us a serious all fight for Jinbei.
Or keep zoro vs lucci but have sanji fight kaku in an all out fight. Fuck man Egghead was such a mess to the extreme especially with the Gorosei too.
Lucci and Drake could have had interesting interactions and thus lucci being the one to betray and try to kill Drake if they were both under Kaido too. Kaido's whole philosophy with the darwinist/survival of the fittest attitude suits luccis beliefs perfectly too. he could truly be himself and be as bloodthirsty as he likes without the WG potentially holding him back.
(I just realised I'm putting Jinbei over Zoro here after Wano too which is a HUGE fuck up ofc lmao. Oops! I'm gonna get shredded, sliced and diced by Zoro fans for this now. Banned from the temple, exiled, on a permanent exodus etc.
My ideas weren't based on powerscaling but actually character history and such. I hate anything being done for powerscaling reasons really, sacrilege to say that here I know. /s)
