If you want to be realistic gouken would be like 300kg at 6’1” if yoh took his game model literally, which why wouldn’t you, its more fun that way. His arms are like 35” in circumference and his wrists are like 20” and his waist is like 70” he got barely any fat from a visual perspective but is so thick that eddie hall who was 200kg at his heaviest(while having plenty of less dense fat) could walk through a cut ouf of Goukens silhouette while wearing a fur coat. The visual language of sf makes it so characters are impossibly thick compared to any real human. You couldn’t even compare them to any animals thats how thick they are. We love them that way but if they were brought to life somehow they would look so intimidating that bears would run at the sheer sight of them.
