Tenkai Knights

A glowing red robot stands in a red-lit chamber, then the scene splits to show four robots in separate colored environments—red, green, yellow, and blue—before they assemble into a larger red and black robot. The assembled robot stands with a yellow robot in a desert-like setting, which then turns to face forward, raising its arms. The setting shifts to a close-up of a green and grey robot with glowing eyes, then back to the yellow robot in the desert, which raises its arms again.
