Part of what we know as the heritage of Iran and India has originated from the Indo-Iranian culture, and this heritage belongs to the East and the common life of Indo –Iranians in the past. We can consider the similarities between Arash-e Kamangir in Iranian mythology and Vishnu in Indian mythology as an original example in this case. In this research, we try to show the characters of Arash-e Kamangir, in the ancient, middle and Islamic periods, according to the comparative method in the French School and the method of content analysis. The results of the research show that Arash and Vishnu are two myths that have a common origin, and consequently, they have vast and widespread common aspects; and in making of mythological character, the subject of the attack between Good and Evil has a special place in the two cultures. Being warrior god of rain in creating the myths like Arash and Vishnu; being bodily and their connection with natural elements and heavenly realms are the other results obtained in this study.
