Review Detail of Spelloyal in I’m Voldemort (MCU Xover)

The fanfic is very good, until the mc becomes avatar of a god and the master of death, in addition to becoming owner and All-Black using death to kill Knull effortlessly. With that the mc becomes op enough to face cosmetic entities and basically makes everything else he has done up to that point useless. The mc is so strong that it no longer makes sense to control the magical world, he spent so much time recreating the super soldier's serum, just so as not to have any more effect on him. It basically became something to give to useless subordinates. Useless because anything that can kill the mc can disintegrate them with a sneeze. Basically, another very cool fanfic spoiled by mc becoming op out of nowhere
