Somebody give this guy a medal because that is some real shit right there. Madara, obito, or really anybody with sharingan or rinnegan rape DBZ verse. And don't give me that "Blow up earth GG" crap cuz anybody who watched DBZ knows that it takes ****ing forever for any of those kind of attacks. While goku or whoever is charging for ten minutes or talking for even longer, genjutsu plus kunai to the throat=GG
Perhaps you should read the other comments.
Even madara's sensing skills won't allow him to react to goku, as goku is 2 times FTL
at least. As I said, goku's energy atacks relies on the amount of energy he can output. He could as well use that energy to throw a punch, making a "force" that would rival the force of his ki blasts.
Considering the power of his ki blasts, one punch and goku can end the battle.
Genjutsu won't work, as kaioken or SSJ willl allow him to disturb his ki flow. Kunais will break.
And ki blasts, they don't take forever. They're slowed down so we can see them. Everything in dbz is slowed down, otherwise, we would see mountains getting destroied, explosions and dialogues.
