what does this mean please someone tell me

Give any strong (or heck, even weak) character a Keyblade and they become a god after what? A few years of training? The pace of learning will most likely vary, but someone like Yamcha or Naruto or Ichigo (or Sukuna, god forbid) getting the Keyblade is TERRIFYING.

Now imagine someone more powerful-let's say Goku, since he's a valid candidate-getting the Keyblade at his current power level. Throw him in the Room of Spirit and Time. Put him through a Mark of Mastery exam. Once he's done? *_Everybody is cooked._*

Keep in mind that Sora got this keyblade like, 5 days after his balls dropped. It took him only _two years,_ most of which spent ASLEEP AND/OR SELF TAUGHT, and he was already ranging from a lower multiversal to outerversal power level, depending on who you ask.

he seems... exotic.

his power was too great, and thus he was sealed until one with a soul of madness would free him to wreak havoc on the world. oh um I mean wahoo
