|This article is about a/an evil Ranger team in Mighty Morphin Power Rangers.|
Six Putty Patrollers were chosen to use the Badges of Darkness, a powerful pseudo morphing device to become the Mutant Rangers. Goldar put them through a training course which involved those Putties learning how to fight like the Power Rangers. However, Goldar destroyed Putty #6 because of its clumsiness (while sending his remains back to Finster's clay pot) as well as the Red Badge of Darkness. Without a Red Mutant, Rita had Finster create Commander Crayfish 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. The female Mutant Rangers were destroyed, while the rest became giant from Rita's magic. The Power Rangers summoned the Ultrazord and destroyed Crayfish and the male Mutant Rangers.

Mutant Ranger Calls
- Commander Crayfish : It's Mutant time! (evil laugh)
- Mutant Blue : I'm after you, blue!
- Mutant Yellow : Hey, Trini, you wanna play too?
- Mutant Black : Nice to meet ya', Zack.
- Mutant Pink : Told you I'd be back.
- The Mutant Rangers are identical to their ranger counterpart's designs with some exceptions such as the design of their gloves, belts and boots being those of Putty Patrollers.
- The weapons used by the Mutant Rangers appear to be generic versions of their counterparts weapons, with Commander Crayfish using a sword similar to Jason's. The Green Mutant Ranger does not use a generic version of the Dragon Dagger, instead being armed with the Sword of Darkness, or at the very least a replication of it. The Mutant Rangers are also not armed with Blade Blasters.
- The Mutant Rangers morph and pose is the same as their Ranger counterparts, but using the Badges of Darkness instead of the normal Morpher.
- Commander Crayfish and the other Mutant Rangers used the civilian weapons from Zyuranger. The Blade Blaster formation using these weapons was not seen in Zyuranger however.
- With no red Mutant Ranger, Commander Crayfish takes on the Red role not only in being the Mutants' leader, but he also mimics Jason's pre-battle pose during the Mutant Ranger roll call, and wields a sword. The would-be Red Mutant was a darker grey then most Putties.
- The Mutant Rangers are the first Evil Ranger Team to not be a copy of their rival team although they have similar suits.
- The Mutant Rangers are voiced by their counterparts' actors using sinister versions of their normal voices.
- They also could morph by placing the badge in their belt.
