In Greek mythology, Orthrus (Orthros) or Orthus (Orthos) (Greek: Ὄρθρος; Ὄρθος) was a two-headed dog and a doublet ("brother") of Cerberus, both whelped by the chthonic monsters Echidna and Typhon. According to some versions, the Drakon Chimaera (his own sister) was in love with him and spawned the Nemean Lion and the deadly Sphinx together.

Orthrus or Orthus was a monster in Greek mythology, a dog with two heads and brother of Cerberus, the three-headed dog that guarded the Underworld. They are multi-headed versions of Houndour and Houndoom, with colours and design elements taken from Zweilous and Hydreigon.

In Greek mythology, Orthus (Orthos) or Orthrus (Orthros) was a two-headed dog, almost as vicious as Cerberus, his brother. The giant Geryon used him to guard his fabulous herds of cattle. As with most of the significant monsters of Greek mythology, Cerberus was considered to be the monstrous offspring of Typhon and Echidna, two serpentine monsters of Greek mythology. The Orthrus Line encompasses Orthrus Houndour and Cerberus Houndoom, which were released as part of the fifty first Mass-Click Weekend on the 4 th of February 2019, and are Exclusive Pokémon. Cerberus was thus brother to the likes of the Lernaean Hydra, the Chimera, and another monstrous dog, Orthrus. They were the offspring of the father and mother of all monsters, Typhoeus and Echidna respectively.
