Vishnu PIE traits

IE gods related to Vishnu (Krishna/Madhava/Ra:ma):
Norse Vidarr
Latin Mars Gradivus (? the pontifex priest)
Greek Herakles, Briareos/Aigaion

Is there any Mitanni god equivalent to Vishnu? I see some IE traits in Bible, specially in Book of Judges and Exodus. Moses had a midianite wife, perhaps there was a Mitanni substratum in some of the Hebraic myths. Moses "opened the Red Sea and crossed it", I think it's a Vishnuvic trait.
