Lone Sloane is a science fiction comics character created in 1966 by the French cartoonist Philippe Druillet.

Lone Sloane first appeared in Druillet's own debut, Mystère des Abîmes, published in 1966.

Other stories were published in the Franco-Belgian comics magazine Pilote from February 1970 to April 1971.

Very similar to Silver Surfer and Galactus, or Ulysses and the Greek gods, he is compelled to wander in a universe that is alien to him.

It is also known for the quasi-baroque style of Druillet's artwork, which features Lovecraftian space nightmares mixed with Escherian mathematically inspired worlds.
