Who is the Buddhist messiah?

Answer 1

In Buddhism the role of "messiah" is not present. This is mainly due to the non-theistic nature of Buddhism(enlightenment comes from within a person, not from the intervention of a deity)

Answer 2

Buddhism has no god, no damnation, no list of rules, no salvation and hence no savior.
The only person really capable of ending the cycle of death and rebirth for you is you.
