Instead of conqueroring the galaxy why not just take the quantum mirror and find a marvel universe and go there and steal tech and blood samples from X-men and other people with powers like Shaw and after Icarus kills Ajak steal her body when he kills her and learn how to harness cosmic energy and do the same with Icarus body when he is killed. and make sure you take the 10 rings from Shang chi they are actually Kang the conquerors main weapon and it makes him immortal and they help him control/power his time chair -that’s a photo of him standing on his time/multiverse travel chair. And just go to parallel world next to his go back in time and conquer it and do it with real god like tech and power.
