Denshi Sentai Denziman

In the past, Queen Hedrian and the Vader Clan attacked Denzi Star and devastated the planet. The Vader Clan later turned their attention to Earth, however, a survivor from the planet Denzi, Denzi Dog IC, sought out five descendants of the Denzi people to become the Denziman and fight against the Vader Clan.

She later recruited Demon King Banriki into the Vader Clan, but eventually wound up getting overthrown by him. After Banriki was defeated by the Denziman, they went to confront Hedrian in her throne room. Before they could do anything to attack her, Hedrian vanished shortly and set her base to self destruct.
