The Vagabond Legend Rangers use the "lost" powers of the 34 previous Ranger teams to fight the evil Armada, whose first wave of invasion forces were completely defeated by the older teams until they arrive with reinforcements and invade the Earth once more, and they must visit the past 34 teams to obtain more power to fight against the ever-determined Armada.
As they continue collecting more Greater Powers, the Vagabond Gang runs into Captain Ruben Blaze's ex-crew mate, Vasura, who is also looking for the Greatest Treasure in the Universe, but he wants it all for himself. To that end, he betrayed his old crew and joined up with the Armada. He opposes the Super Megaforce Rangers with his own set of Ranger Keys and his partner Sally, a monkey-like alien who can summon Giant Battle Pseudo-Lifeforms.
Eventually, Lain joins the crew as the Super Megaforce Silver Ranger after obtaining his gear from three former Rangers (Tommy Oliver, Eric Myers, and Trent Fernandez) and proving himself worthy of being a Power Ranger. As a Power Rangers superfan, his knowledge of Ranger teams as well as pre-Zyuranger Super Sentai teams aids the the core five in their fight against the Armada and Vasura.
