I know Goku would win at his current state (Battle of Gods) and anything from after Goku's gravity training, Namek saga - Buu saga onwards.
So I'm going to restrict Goku ALOT. Goku cannot use Kamehameha or any move that requires Ki. He will only use his physical capabilities. i.e Strength,Speed,Durability,Endurance etc.
This is Goku right after he finishes his fight with Vegeta in the Saiya-jin saga. (when he re-cooperates) so his strength has increased after healing because he is a Saiya-jin and his power increases after healing from near death experiences.
Everyone other than Goku is at full power.
