Next to a life-size Stormtrooper replica or an authentic lightsaber, the Darth Vader robotic arm from Uncle Milton is quite possibly the coolest Star Wars–related toy we've seen this year. Vader's arm, which comprises 45 pieces (you build it yourself), is fully controllable, but it's not powerful enough to force-choke your enemies — not unless your midi-chlorian count is as high as Anakin Skywalker's.
