ROBERT GARRISON from the original "Karate Kid" died Friday morning.  He was only 59.

He had been battling kidney and liver issues.

Garrison played one of the bad kids from the Cobra Kai dojo . . . and he's the one who delivered the line, "Get him a body bag!  Yeah!"

Robert's character Tommy was brought back for YouTube's "Cobra Kai" series.  He died during a camping trip in season two, and the scene ends with him being zipped up in a body bag.
