Mutant Rangers

History
Six Putties were chosen to use the Badges of Darkness a powerful pseudo morphing device to become the Mutant Rangers. However, Goldar destroyed Putty #6 because of its clumsiness, as well as the Red Badge of Darkness. Without a Red Mutant, Rita chose her Commander Crayfish monster to lead them. When "morphed", the Mutants could mimic the voice of their opposing Ranger. The Mutants even had their own Power Blaster, which Zordon countered by giving the Power Rangers stronger versions of their old weapons. In a Blaster vs. Blaster fight, the new weapons proved too much for Crayfish and the Mutant Rangers. Pink and Yellow were destroyed, while the rest became giant from Rita's magic. The Power Rangers summoned the Ultrazord and destroyed Crayfish and the Mutants.

Difference

 * All Mutant Rangers are identical to their ranger counterpart with some exceptions such as the design of their gloves and boots.
 * All Mutant Rangers morph in the similar ways with their rangers counterpart but using Badge of Darkness instead of normal Morpher

Trivia

 * The Green Mutant Ranger fought using the Sword of Darkness, which was vaporized by Jason's Blade Blaster earlier in the series. Crayfish and the other Mutants used weapons similar to the civilian weapons of the Zyurangers.
