Mark X Executioner
The Mark X Executioner was a gladiator droid built by Arakyd Industries. Galactic customers for whom the droid was in demand included bored dictators and their subjects. The droids were not, of course, invincible and could be destroyed by well-aimed energy bolts or laser scalpels, if used correctly, as shown, on one occasion, by a buzz droid in a gladiator tournament.
The tall droid moved on two caterpillar tracks—a dual-tread drive system—and was outfitted with a variety of weapons and heavy armor. Its multiple weapon-arms included a neuron whip, vibro-ax, blaster rifle, missile launcher, flame projector, and a primitive spiked club.
