The natures of these are as mysterious as the Stranger himself, who seems to be effectively immortal, never aging. The Phantom Stranger has demonstrated enormous powers and capabilities, the exact origin of which is undetermined. He can travel enormous distances in a very short period of time, such as to the JLA Watchtower and Apokolips, as well as to mystical dimensions, such as Heaven, Hell and the realm occupied by the Quintessence (although he is forbidden from entering Heaven directly). He can fire energy bolts of great force, travel through time, dispel magic, reveal illusions, and survive in space without any type of life support system; on one occasion, he created a mystical shield that protected Superman from any spells cast against him directly in preparation for Superman's upcoming confrontation with Arion. The limits of his power have not been defined. In many cases, despite his obvious capabilities, he claims he is not allowed to end a crisis directly, only to guide others to take the necessary actions (this restriction allows the Stranger to guest-star in virtually any title without becoming a "deus ex machina", whose actions would immediately end the story).
