I immediately loved the robot battles of Timeranger. The visuals where simply stunning, and most of the battles where with the sun eclipsed - essentially setting the battles at night.
And I simply loved how the robots came into the past era, being rocket away by a hammer, through the time-gate, and then flying through time to meet the Timerangers.
Well, here are some images of the robots. Enjoy.
