Talk:Humanity's Hope Super Saiyan Trunks (Future)/@comment-5741122-20161117175624/@comment-5741122-20161213140116

The people's hope and belif that Trunks would save them resulted in them unconciously giving him their energy, which Trunks unconciously gathered all at once to make a Spirit Bomb. There really isn't an explanation needed.

And Trunks wasn't stronger than Vegito (not by a long shot). He was just strong enough to finish the job.
