Stone guardian

Stone guardians are powerful stone statues of zealots used by the Tal'darim to defend an alien artifact from being stolen by Raynor's Raiders on Monlyth.

The stone guardians have beam weapons which resemble those of the colossus, though stone guardians can also attack air units.

They look like normal zealot statues before being activated.
