The Megaforce Intro is the opening sequence and song to the 20th season of Power Rangers, titled Power Rangers Megaforce. It was introduced in Mega Mission, and last heard in Legendary Battle. While the song has remained the same, since the episode 10, the intro undergoes a change with the addition of the Ultra Mode, Vrak's Earth Armor, Bluefur and Bigs, and Creepox subtraction between the main villains, featuring scenes with Robo Knight, new monsters, the Sea, Sky and Land Brothers Zords and the Ultra Gosei Great Megazord. The OP then changes again at the start of Super Megaforce, but the song remains intact.
