The Dimetro Zord is the Black Dino Ranger's Zord. The zord can attach itself as an arm on the Thundersaurus Megazord, using the Dimetro Blade attack/finisher. When not attached onto the Thundersaurus Megazord, the Dimetro Zord can use its saw on its back as a weapon as well as its aggressive nature. The saw on its back is strong enough to break an enemy's weapon.

The Dimetro Zord was originally found as en egg by Elsa and was used to attack the Dino Zords. Dr. Oliver was able to tame the Zord by using his morpher.
