'Batman' Star Burt Ward -- Hey DC Comics ... DON'T KILL ROBIN!!!

DC Comics is making a huge mistake by killing off Batman's iconic sidekick Robin in the newest issue ... so says the most famous Robin ever, who tells TMZ, the future of the Batman franchise DEPENDS on the Boy Wonder.

DC is slated to kill off Robin in the next issue of the "Batman Incorporated" series -- but Burt Ward (who played Robin in the 60s TV show) has one thing to say ... "Holy self-inflicted wound! Not good for corporate profits!”

Ward tells us, "It’s a terrible choice to kill off Robin. Why bite the hand that feeds you? ... Robin should only die in people's imaginations! Or in a state of primal ecstasy!"

FYI -- It's not the first time Robin's been killed off in the comics ... DC previously did him in back in 1988 when fans voted to off the character.

Nevertheless, Burt adds, "Every youngster realizes that he or she is too young to drive and they are not big like Batman. So, they all yearn to be Robin who gets to RIDE WITH BATMAN AND FIGHT WITH BATMAN!"

He's got a point.
