Nah. Instant transmission boyy

Doesn't that only work across distances? I didn't know he could travel through time

Pretty sure goku just blows up all the planets he wants and wins...

Unfortunately it takes time for him to charge. Sure he can blow up wherever Atheon sends him to, but he can't make his way back, I don't know if he'd die from the lost in time, but he certainly wouldn't be able to return to the destiny timeline. Although, that is the only destiny character that could do anything to him.

If I remember correctly, all goku needs to know for instant transmission is the place he thinks about. If he gets sent somewhere else he'll just think back to the vault or anywhere else.
