He cannot destroy a city never mind a universe :-p. But seriously still no, Goku never match the universe shaking feat again.

If goku learned self destruct yeah I could see it happening

Goku self destructs with all his might and creates a crater 380 kilometers in diameter.

Goku is too stupid to be a terrorist. He'd fall asleep with the bomb or something stupid like that

@hypnos0929: In this scenario Goku IS the bomb. Remember when Vegeta or Chaozu blew themselves up?

@mainjp: In that case Goku will fall asleep, or not blow himself up when people tell him we don't have an other world. Or we'd tell him to get to the strongest fighters he has to go to the surface of Venus then we'll just wait.

No

I don't think he can.

What's his political agenda

Is this current Goku (MUI)? Then maybe.

there's not really enough data to assume he can destroy the universe on his own thru self destruct. i mean two GoD level beings have to clash overtime for the universe to be endangered but one GoD level alone ? needs more things to ponder on.

Why would he explode himself instead of just destroying it?
