Both Odin and Adinath are ancestral figures to their worshippers. Odin is called Allfather and considered the ancestor of many European tribes and royal houses, including the Langobards.
Adinath, also called Rishabha (bull) and Ikshvaku (sugarcane), was founder of the Ikshvaku dynasty, from whom many ancient Hindu kings and deities, such as Sagara, Rama and Krishna, claim descent.
Sons of Adinath include Bhadrasena, Vidharba, Avirhotra, Ilavarta, Malaya, Kikata, Ketu, Bahubali, Chamas, and Bharata.
Sons of Odin include Baldr, Vitharr, Hodr, Yngvi-Freyr, Meili, Sigi, Hreksjoth, Vali, Hermothr, and Bragi.
Both Odin and Adinath are associated with writing systems. Odin is said to have won knowledge of Runic writing by enduring loss of an eye and surviving an ordeal of being suspended from an oak tree for 9 days. Adinath is said to have invented the Indian writing system called Brahmi script, which he named after his daughter.
Some depictions of Shiva in Hindu art show him with a trident spear. The trident spear is also wielded by Odin in Norse art.
Odin rode an eight-footed horse.
When Adinath retired from his reign, he went to live on Ashtapada (eight-footed) mountain.
The 14 Purvas, a set of lost Jain scriptures, allegedly contained material in one section which told how to attain magic powers.
The Havamal or Sayings of Odin is part of the Norse Poetic Edda. In the Havamal there is a boasting song in which Odin recounts the magical feats which he can perform.
