Settle down, children! Class is in session!
Can anyone tell me the purpose of the God Valley Incident?
Answer: Setup.
The Rocks Pirates’ reason for going and their break-up, mostly meaningless. Just a means to an end. That end is, of course, being How To Take Down The World Government (and Imu).
Joyboy took his shot and missed. Rocks, a decendent of Davy D. Jones, never got to see his plans fully go to fruition before dying. BUT, in doing so, allowed his son, Blackbeard, to survive and give it the ole Davy try in the present. And while Blackbeard isn’t ready to destroy the World Government, he’s well on his way! He’s got the crew, the darkness-darkness fruit, and someone willing to spill the beans on Pluton’s hidden location beneath Wano.
What’s left for Blackbeard to do before giving the World Government the D. Clan boot? Finding the One Piece! Whatever’s on Laugh Tale may be the key to ultimately destroying the WG and Blackbeard needs it! That and some Eternal Flame to power Pluton. What? You think it’s gonna run on AA batteries? But that’s a discussion for another time.
So, Rocks is dead, but we learned Imu’s Domi Reversi curse can be reversed with enough haki. I smell a Luffy and Loki team-up against Imu!
Oda skipped a scene showing Rayleigh and Gaban saving Roger and Garp from God’s Knights. Why? Heck if I know. Probably to hide Gaban’s knowledge that Supreme King haki infused attacks affects the Knights ability to regenerate. Absolutely unnecessary. Every fricking thing doesn’t need to be hidden up to the last second, Oda!
The Roger Pirates find Baby Shanks inside of a treasure chest. I guess his full name’s printed on his clothes somewhere. Hey, mom had to tell him and Shamrock apart someway.
