Centurion droid

The Centurion guards exist in many versions of Generation 1 continuity.

We make Sentinel units look smart.

The Centurions are an automated defense guarding the Vector Sigma supercomputer. Thous psoessing no weapons, Centurions are trained in hand-to-hand combat to stop all intruders. They tend to be encountered in large numbers.

They must be either evaded or tricked to approach Vector Sigma- fortunately that's not hard.

Centurion guards appear to be nonliving machines.
