Oda destroyed you
We weren't supposed to see the sky splitting in GV because Oda forgot about it and came up with a new scale to show power because Garp and Aokiji couldn't split the sky and their clash is stronger than the clash of the other Yonko
If Rocks could split the sky by himself then why didn't it happen in the battle with Harald?
And if it's Imo's power then it has nothing to do with Rocks
You're changing color a lot kid
