A/N: so it turns out that wasn't super saiyan blue gogeta for the 4d dragon ball ride. I went on the wiki today and found out the real name. It's Goku (Audience Fused).

Here's what it Said in the page.

Goku (Audience Fused) is the result of Goku performing the Fusion Dance with audience member(s) of Dragon Ball Z: Super Tenkaichi Budokai.

When Super Saiyan Blue Goku finds that he is unable to defeat Broly God, he fuses with the audience. The resulting fusion fires a God Kamehameha at Broly, destroying him.

Austin: now this proves my point. God Broly "is" weaker than Merged Zamasu and Vegito Blue.
