Who would win if the GOTG fought each other

MCU: Star Lord (if he has Celestial Powers) or either Rocket (he's smart) or Adult Groot (really powerful).
Don't know about the comics though...

Rocket he is way smarter and more agile then groot

Rocket could literally headshot them all.

Na groot impales them all.

Groot lol

Gamora would be the last one standing. She is the most well rounded fighter on the team, her enhancements would allow her to deal with Groot and Drax's strength, her skill, versatility, and sheer speed are to much for most of the guardians to consistently deal with.

I say Rocket

Groot solos entire rest ( Or Yondu one shots everyone )

Rules:
Movie versions
Star lord is not celestial
Groot is an adult
