Mythical many-headed creatures

In Hinduism, Uchchaihshravas (Sanskrit: उच्चैःश्रवस्, IAST: Uccaiḥśravas or Sanskrit: उच्चैःश्रवा:, IAST: Uccaiḥśravāḥ), (lit. 'long-ears' or 'neighing aloud'') is a seven-headed flying horse, created during the churning of the ocean. It is considered the best of horses, as prototype and king of the horses. Uchchaihshravas is often described as a vahana of Indra, but is also recorded to be the horse of Bali, the king of the asuras. Uchchaihshravas is said to be snowy white in colour.

In Greek mythology, Cerberus (or Ancient Greek: Κέρβερος Kérberos), often referred to as the hound of Hades, is a multi-headed dog that guards the gates of the underworld to prevent the dead from leaving. He was the offspring of the monsters Echidna and Typhon, and was usually described as having three heads, a serpent for a tail, and snakes protruding from his body. Cerberus is primarily known for his capture by Heracles, the last of Heracles' twelve labours.

Shesha (Sanskrit: शेष, Śeṣa, 'Remainder'), also known by his epithets Sheshanaga (Sanskrit: शेषनाग, Śeṣanāga, 'The snake Shesha') and Adishesha (Sanskrit: आदिशेष, Ādiśeṣa, 'First Shesha'), is a serpentine demigod (naga) and king of the serpents (Nagaraja), as well as a primordial being of creation in Hinduism. In the Puranas, Shesha is said to hold all the planets of the universe on his hoods and to constantly sing the glories of Vishnu from all his mouths. He is sometimes referred to as Ananta Shesha.

The double-headed eagle is an iconographic symbol originating in the Bronze Age. The earliest predecessors of the symbol can be found in Mycenaean Greece and in the Ancient Near East, especially in Mesopotamian and Hittite iconography. Most modern uses of the emblem are directly or indirectly associated with its use by the Palaiologos dynasty of the Byzantine Empire, a use possibly derived from the Roman Imperial Aquila. High medieval iterations of the motif can be found in Islamic Spain, France, the Bulgarian Empire and the Serbian principality of Raška. From the 13th century onward it appeared within the Islamic world in the Seljuk Sultanate of Rum and the Mamluk Sultanate, and within the Christian world in Albania, the Holy Roman Empire, Russia, and Serbia. In a few places, among them the Holy Roman Empire and Russia, the motif was further augmented to create the less prominent triple-headed eagle.

Triglav (lit. "Three-headed one") was the chief god of the Pomeranian and probably some of the Polabian Slavs, worshipped in Szczecin, Wolin and probably Brenna (now Brandenburg). His cult is attested to in several biographies of the bishop St. Otto of Bamberg in the years immediately preceding his suppression of it in 1127.

Svetovit, also known as Sventovit and Svantovit amongst other variants, is the god of abundance and war, and the chief god of the Slavic tribe of the Rani, and later of all the Polabian Slavs. His organized cult was located on the island of Rügen, at Cape Arkona, where his main temple was also located. According to the descriptions of medieval chroniclers, the statue representing this god had four heads and held a horn and a sword. Dedicated to the deity were a white horse, a saddle, a bit, a flag, and eagles. Once a year, after the harvest, a large festival was held in his honor. With the help of a horn and a horse belonging to the god, the priests carried out divinations, and at night the god himself rode a horse to fight his enemies. His name can be translated as "Strong Lord" or "Holy Lord". In the past it was often mistakenly believed that the cult of Svetovit originated from St. Vitus. Among scholars of Slavic mythology, Svetovit is often regarded as a Polabian hypostasis of Pan-Slavic god Perun. His cult was destroyed in 1168.

The Lernaean Hydra or Hydra of Lerna (Ancient Greek: Λερναῖα ὕδρα, Lernaîa Húdrā), more often known simply as the Hydra, is a serpentine lake monster in Greek mythology and Roman mythology. Its lair was the lake of Lerna in the Argolid, which was also the site of the myth of the Danaïdes. Lerna was reputed to be an entrance to the Underworld, and archaeology has established it as a sacred site older than Mycenaean Argos. In the canonical Hydra myth, the monster is killed by Heracles (Hercules) as the second of his Twelve Labors.

According to Greek mythology, the Chimera, Chimaera, Chimæra, or Khimaira (ky-MEER-ə, kih-, -⁠MAIR-; Ancient Greek: Χίμαιρα, Chímaira, 'she-goat') was a monstrous fire-breathing hybrid creature from Lycia, Asia Minor, composed of different animal parts. Typically, it is depicted as a lion with a goat's head protruding from its back and a tail ending with a snake's head. Some representations also include dragon's wings. It was an offspring of Typhon and Echidna and a sibling of monsters like Cerberus and the Lernaean Hydra.

The three-headed eagle, also called triple-headed eagle, is a mythological or heraldic bird, as it were an augmented version of the double-headed eagle.

Yamata no Orochi (ヤマタノオロチ, also written as 八岐大蛇, 八俣遠呂智 or 八俣遠呂知) is a legendary eight-headed and eight-tailed serpent that appears in Japanese mythology. Both the Kojiki and Nihon Shoki record the serpent as being slain by the god Susanoo, in order to rescue the goddess Kushinada-hime. It is also noted that the Kusanagi-no-Tsurugi, one of the Three Sacred Treasures, was found within the serpent's tail.
