Power Rangers Season 8 Episode 13

Ryan's Destiny

Diabolico unleashes his three most powerful monsters who threaten the city with explosive feathers. The Rangers are no match against them, until Ryan comes to terms with his evil past and becomes the Titanium Ranger again to fight for good. However, Ryan is penalized for his treason against Diabolico by the means of a Cobra tattoo, which will slither up his back every time he morphs until it reaches his neck and bites, thus destroying him.
