Diabolico brings back his three generals merged as one monster, Troika, which the Rangers destroy with their new Battle Boosters. Diabolico then goes down himself and battles the Rangers, taking down the Supertrain Megazord. Ryan finds the cobra tattoo's power source, a cobra monster from the tomb, and destroys it, lifting the curse. He joins the Rangers and helps them defeat Diabolico with a new Zord combination - the Lightspeed Solarzord.
