GT Son Goku (Upgrade).

[Why_are_all_the_good_usernames_taken?_rs]

I think he should be higher than multi solar system level.

Here are a few feats/statements.

1. He shook hell, a universal size realm in base form.

The size of hell^^^

2. Competes with Omega Shenron (and kills via the Universal spirit bomb).

Who can: one of the best feat of the Franchise, his dragon balls (lol), contaminates the Galaxy with their presence.:

Omega Shenron says he will lay waste to the universe which is universe 7

Confirmed when he blows up the universe on panel under 1 second in the anime:

Then is confirmed that the explosion would also destroy the Kaioshin realm off panel, a dimension outside the universe and further beyond then the AfterLife.

This means the blast would also have destroyed that dimension in order to destroy the Kaioshin Realm.

They were also worried about the explosion reaching them, in a realtiveky short time.

3.Destroys a space-time continuum with an unknown size:

With all these he should at least be multi galatic.

Also, before anyone brings up how massively this would contradict the power scaling from the Dragon Ball Z manga, it takes place in a alternate diemension/reality.

It is it's own side story, with diffrent power scaling.
