In the end, though, it would pretty much just become an endless sparring match for him. Goku would beat them into submission, sure, but he wouldn't ask them to stop fighting him. In fact, he would ask them to fight again. Fighting is the one thing he enjoys in life (well, besides food). Guardians may try to fight very seriously, however it will just be a fun game for Goku. Technical win goes to Goku, however the fight goes on for all time.
