London, May 1 : Sylvester Stallone, who is writing his fifth `Rambo' movie, plans to retire his famous alter-ego John Rambo in the final instalment.

Stallone, 65, who will be seen alongside an amazing collection of movie stars including Arnold Schwarzenegger, Jet Li, Bruce Willis, Dolph Lundgren, Jean-Claude Van Damme, Chuck Norris and Jason Statham in `The Expendables 2' later this year, says battle-worn Vietnam vet Rambo will go out with a bang in Mexico.

"He realises what his destiny really is," the daily Express quoted him as saying.

"It's not to be a farmer, it's not to be obscure; it's to go out in a blaze of glory in a heroic fashion... That's who he is. I'm working on a formula for it right now," he added.

Stallone first appeared as `Rambo' in 1982 and has played the character four times to date, the last being in 2008. (ANI)
