THE STORY
Determined to rid the universe of the Power Rangers once and for all, Lord Zedd has an arsenal of monsters inspired by Earthly plants and animals. To battle these new villains the Power Rangers are armed with new powers, new Thunderzords, and joined by the powerful White Ranger, who’s armed with Saba, the talking tiger sword and the mighty White Tiger Zord! Go, Go, Power Rangers!

Spiffy.

Looks nice.
