10 Justice League Members More Powerful Than Superman
1. The Phantom Stranger
First of all, the Phantom Stranger is a true immortal. There is no way for him to die, literally, he doesn't age and even the Specter, "God's Wrath", seems to be unable to kill him.
He is also omniscient, knowing anything that was, is or will ever be across multiple universes and even displays knowledge of the Marvel Universe. He can cast spells, teleport through infinite distances, survive in the vacuum of space and travel through time and other dimensions.
The limit of his power has never been defined in his 68 years of publication. To prevent him from coming in and making every single story completely redundant, he has stated multiple times that he is unable to prevent or end any event of real significance to the universe.
Often providing information about incoming danger, helping fight immediate threats and acting as an advisor and honorary member of the Justice League, the Phantom Stranger is one of DC's god-like figures, basically being a tangible divine entity that spans not only the prime continuity, but all universes.
So, you still believe Superman is overpowered?
