Sentai

Sentai is a tokusatsu subgenre centered on a color-coded team of superheroes—typically led by a red ranger—who use unique weapons, martial arts, and advanced technology to fight evil forces through intense teamwork. A defining hallmark of the genre is its escalating combat structure, where a ground-level martial arts victory forces the defeated villain to grow to colossal proportions, prompting the heroes to pilot separate vehicles that combine into a singular giant humanoid robot.
