Hakaida is alive (as much as robot with a human's brain in it head can be alive) but he is a prisoner of The Shadow and he is not happy about it. Big Shadow is seen for the first, and appears to literally be a large shadow. Red Faced Tortoise and the new monster Lady Ghost are killed with "Blast End" as Kikaida-01 begins his dismantling of the Shadow organization. its a long road.
