Rama was an avatar of Vishnu and a great god in the Hindu religion.
He was assisted by Hanuman when he killed the father of Indrajit, King of Demons.
Tataka manipulated people from all over India to ally against Rama and attempt to kill him.
Although not explicitly stated, Krishna is Vishnu's next avatar after Rama. Since Eli is identified as an avatar, it is possible that the writers originally intended for him to be the next avatar (which would technically make him the Buddha), but changed it later.
