The Death Star II was the second version of the original Death Star. Like the Death Star wasn't enough of a bringer of death. Palpatine decided to make a bigger version of the ball, and protected it by a small shield generator on the planet of Endor. The bigger the better, I bet the only flaw of the whole thing was the gaping motherfucking gynormous hole on half the Death Star. Yeah it would have been perfect if they just patched up that 800km by 800km hole on the opposite side of the so called superfortress.
