Dragon Ball (Warning: Untagged Spoilers) in Chit-Chat Posted June 21 Next Super manga chapter's out. Not much going on plot wise, it's been focused on the fighting. However, lore was added that explains future events. Grand Kaioshin and Merus surmise during the fight with Moro that while his spirit and persona is a part of Good Buu, Grand Kaioshin's godly ki and overall power were transferred to Evil Buu when Good Buu blew his stack back then. That godly ki would remain with Evil Buu all the way up to Kid Buu and eventually go with Kid Buu after the Spirit Bomb destroyed him. But, Kid Buu was reincarnated into Uub. And the power went along for the ride. So the reason why Uub is able to keep up with Goku at EoZ, after the events of Super and all of Goku's powering up during that era, is because Uub himself possesses Grand Kaioshin's godly ki, albeit unknowingly. So that, combined with Kid Buu's own enormous raw power, makes Uub a potentially superb fighter able to keep up with the Super Saiyan Blues and Broly.
