The Nightosphere is an alternate dimension appearing in "It Came from the Nightosphere," ruled by Hunson Abadeer and inhabited by a multitude of other Demons. In the episode "It Came from the Nightosphere," a portal between the Nightosphere and Land of Ooo, formed in Marceline's house, led to a place engulfed in fire. Details of the place were eventually exemplified in "Return to the Nightosphere" and "Daddy's Little Monster," where it was viewed to be a demonic wasteland filled with chaos. The dimension can be escaped by going through a portal in Hunson's house.

How to get there

  1. First draw a happy face on a surface.
  2. Douse the face with some bug milk.
  3. Chant, "Maloso vobiscum et cum spiritum!"


  • "Maloso vobiscum et cum spiritum" roughly translates from Latin to: "Evil be with you and with your spirit." This phrase may be a reference to the Catholic liturgy, where the priest says "Dominus vobiscum" ("The Lord be with you"), and the congregation responds "et cum spiritu tuo" ("and with your spirit").
  • The Nightosphere bears similarities to Hell in appearance. In addition, Finn states, "I'll see you in the Nightosphere, you sick freak," which is similar to the phrase "I'll see you in Hell."
  • The Nightosphere also exists in the gender-swapped universe, as Marshall Lee claims to be from there.
  • The inhabitants of the Nightosphere extrude banana-like waste from their ears. All demons consider the substance to be disgusting.

Cultural references

  • The depiction of the Nightosphere is inspired by the artwork of Hieronymus Bosch, in particular, the right panel of the triptych "The Garden of Earthly Delight." Note especially the giant, long-legged white creature with a bisected mouth/torso who carries people around like a bus. Another possible inspiration is Pieter Bruegel's Hellscapes (which were themselves inspired by Bosch).
  • The Nightosphere has many resemblances to the Nether in Mojang's sandbox game, Minecraft.
  • In a way, the Nightosphere is almost similar to Ben 10’s “the Null Void”.
    • Both are alternate dimensions full of unimaginable danger.
    • Both involve banishment. Marceline banished her evil dad to the Nightosphere, and the Null Void is where the galaxy worst of the worst are banished.
