No I'm not saying he is as powerful as the others because he beat Roma. I'm saying he can go to any dimension or any realm and still be powerful, immensely powerful. Him roaming the earth wouldnt cause him to lose any of his power as mephisto was when black panther cut him off rom his power source. So it's not about who he has beaten that makes him stronger imo. It's that he can go anywhere and still retain ALL of his power. Do you see the difference in that?
