Series Power Rangers Zeo

The Zeo Crystal is one of the most powerful forces in the Universe. It was once sought by Master Vile, but the Rangers were able to divide it into five shards and scatter them through time.

The Rangers recovered the shards and used them to return the Earth to its natural timeline, then used it to fuel their new suits and weapons.
