Yes they are a team now.
Superman has lost to Captain Marvel a few times and vegeta and goku are close but goku would be stronger than him and you have the Green team. I dont have to say anything about them cause it is just such a badass team
Goku
Superman
Vs
Captian Marvel
Vegeta
Vs
Piccolo & Martian Manhunter
Who take this fight will it be.
The hope of the universe and the last son of krypton.
The proud Prince and the magical Shazam
or the most badass team ever
