Calling this one 'Final Form'. My idea is that the guy on the left is transformed, either by science, magic, or just a weird second growth spurt, into an exaggeratedly tall, muscular, hung version of his younger self - or that time travel is involved and he's transported back in time but with an 'enhanced' body. It could also be seen as #SPH with two different guys!
