Marvel Universe Edit
In the Marvel Universe, the Astral Plane is the realm of minds. Telepaths are able to access the Astral Plane by projecting their mind onto this realm, more commonly known as Astral Projecting, this also allowing them to enter the minds of others. The realm plays a significant role in the stories of many characters.Doctor Strange has practiced astral projection since his inception in 1963. Illyana Rasputin [alias Magik] was able to astral project her own consciousness in New Mutants (Series 1) #15. Other mutants such as Professor X, Emma Frost, Jean Grey, and other powerful psychics, have access to the astral plane. Professor X imprisons the Shadow King on the astral plane. There are beings who live there such as Cassandra Nova. The Hulk is capable of seeing astral bodies.
- In Cartoon Network's Adventure Time, Finn the Human attempts to enter the Astral Plane in his mind to summon an "Astral Beast" to free him and his best friend Jake the Dog from the clutches of the Ice King.
- In the DC/Vertigo Universe, the Astral planes are used for travel and magic by a certain number of individuals such as Doctor Fate, Zatanna, and Doctor Occult, though use of astral projection is mostly illusory.
