I always want to imagine how would it have gone if Vegeta and Goku had entered the ROSAT together. Though, considering their individual characters in this stage of development, it would have been almost unmaginable. The idea still fascinated me, especially after seeing this picture. Of course in-universe, Vegeta would never accept it and there’s still Trunks and Gohan, but say if they had to enter it. At this point , they still hated each other’s guts and if you think about it, Vegeta’s death was the only time they are allowed and allowed themselves some sort of interaction and closure that’s not in battle ; Goku may have understood the Saiyan pride and Vegeta may be fiaxed with Goku, they never could get alone. At the same time, they have a certain strange mutual respect between them - Goku said Vegeta was a great fighter , a genius ; Vegeta considered Goku a worthy opponent, the legend of his dreams, and given that he knew Goku was sick while himself was well and kicking and saved Goku for later fighting,It’s also really hard to think that they would try and beat each other to hell all the time in the chamber. More like Vegeta trying his best to avoid Goku and hide his training and Goku trying to spare Vegeta’s pride as best he could and minding his own business and they secretly picking up each other’s thinking and techniques from distances.
Goku’s serene, peaceful ice of emptiness and Vegeta’s dark, hellish fire of ego would be the only two things that collided in fierce battle of the mind.
