Bio Dino Zords

Originally sent to attack the city while under the control of Mesogog, the Bio Dino Zords were quickly tamed and captured by the Rangers. At first, the Zords proved difficult to control, but the Rangers learned to combine them with ease. 

The Zords were originally designed and created by research carried out by Dr Tommy Oliver and Dr Anton Mercer. The Zords were then used for evil by Mercer's alter ego, Mesogog.

Ultimately, the Dino Zords were destroyed by Zeltrax in his evil Zord, the Zelzord.
