It's Maskman and Turboranger for me. The former is the best sentai of the 80s while the latter had one of the coolest giant robots ever in Turbo Robo (w/matching shades) as well as having one of the strongest Red Warriors ever in Red Turbo, a very powerful sword-wielding sentai warrior which is probably rivaled only by Magi Red. Turboranger also had one of the best pair of villains in Yamimaru and Kirika, a duo which can only be rivaled by Rio and Mere in terms of strength and greatness. However, Maskman's serious storyline and Aura Power still tops my list of favorites from the glorious 80s decade of Super Sentai. Turboranger, carriers of the Yosei Power and Jidousha Power according to the lyrics from "Moeru Super Sentai Damashii," is a close second.
