Oh, they looks great as expected. That solider is probably an elite version, because the preview showed green soliders in large ammount, blue soliders in some ammount and a couple of white ones, with some Sally-Kinggon looking kaijin.
Considering villains don't send random monsters to attack Tokyo, as they usually do, but heroes going through universe fighting for freedom, it probably be a monster per planet. And looking at large numbers of Kuytamas, probably new one per planet too. I'm wondering how strong they are, because we needed the power of every sentai ever to repel Zangyak twice, and we are not having that this time.
"Saban's Power Rangers Ninja Steel starts deep in space, where Galvanax is the reigning champion of the most popular intergalactic game show in the universe, and monsters battle to prove who is the mightiest warrior. Zircon is determined to become invincible by controlling the mythical Spirit Crystal, which contains six supernatural Ninja Power Throwing Stars. The only thing standing in his way is a new team of heroic teenage Power Rangers who possess the Spirit Crystal. The evil Galvanax sends his warrior contestants down to Earth to steal the Crystal, where each epic battle against the Rangers is broadcast throughout the universe. Together, the Rangers must master their arsenal of Throwing Stars, Zords and Megazords, each made of legendary ninja steel, in order to stop this evil threat and save our planet from destruction."
