Quick custom Gladiator Droid. The torso and arms are from two "I dunno" figs, the legs are from a Magnadroid, the backpack is from an Armored Cobra Commander from WAY back when and the blades are from a Toybiz Wolverine (also from WAY back).
Gladiator Droid RR-X19g "Falco". Built on a smaller frame than most Galdiator Droids, the RR-X series relied on speed and agility rather than brute force or firepower. Extermely fast and maneuverable, equipped with a repulsor generator backpack most owners equipped the RR-X series with bladed weapons. The unit 19g, known as "Falco" was hailed throughout the fighting circuit and was a six time Universal Fighting Droid Champion. Equipped with a matched set of Phriik vibroblades, Falco is a force to be reckoned with in the ring.
The legs are slightly two narrow for the body, but I feel that helps enforce the "bird" motif found in the head and armor hardpoints on the arms and torso.
