Monsters gone good - Power Rangers

This was requested by one of my Facebook friends. Not all ugly monsters are evil.

Mr. Ticklesneezer (MMPR Season 1)

Even though just Trini's dream, he was a good-hearted doll Rita got to do what she wanted.

Bookala (MMPR Season 2)

Bookala was an good alien, Aisha made a little toy that was turned evil by Lord Zedd and then was good again and sent back home.

Defector (Zeo)

He tried to trick the Rangers into thinking he was good and left the Machine Empire. Klank then arrived to cause pain to Defector with a remote control. Rocky went to check on him, and he responded by attacking the Rangers. Rocky then went on the attack, and soon afterwards Tommy called on the Defender Wheel. So he wasn't really good, it was all a trick. He didn't survive.

Visceron (Turbo)
Dimitria's ally from Inquiris was deformed and brainwashed into Divatox's servant by Porto's transformation spray. Divatox then used him to plant a detonator at the KAGV Radio Studio. He was reverted back to normal when the detonator blew up in his hand during battle. He was revived shortly after that to deliver his message to Dimitria. 

 Waspicable (In Space)
A sweet-natured monster bullied by Sting King to be evil and as much as he tried he couldn't. He befriended Cassie and she felt compassion for the monster after realizing she hurt his feelings. When forced to destroy Cassie, Waspicable shot a Quantron beside her. Waspicable loved flowers and returned balloons to a little girl. He survived. He was a re-paint of a monster costume used for Season 1 of MMPR (Grumble Bee?).

  Seymour (In Space)
Seymour was a cute little Anglefish-like alien from Tirna that ran away from his master Jakarak and was saved by Andros. Andros told Seymour to scurry away but he stowawayed on the Astro Megaship. Seymour had an insatiable hunger and eventually grew to an adult form. After confronting his former master, Seymour was teleported to Tirna and met a cute female alien.

Deviot exploded Loyax when he had the Galaxy Megazord tried to remove the device.

     Itassis 

Itassis is a faithful follower of the rules of darkness and won't let anything get in the way of them being followed - even if that means helping the Power Rangers.

They responded it was courage, which she ultimately used to defeat Sculpin and help the rangers defeat the Master freeing herself from the puppet's strings.

    Norg (PROO)

His home was invaded by Flurious and is forced, sometimes willingly, to do dirty work for Flurious. He wounded himself and was healed by Tyzonn and Rose. He return the favor by saving Tyzonn's life using a healing ritual after he was wounded by the Fearcats. Norg befriends Tyzonn's fiancee, Vella, who notices his gentle nature. When Flurious completed the Corona Aurora, Flurious instructs his Chillers to dispose of Vella and Norg and this causes Norg to destroy all the Chillers left behind. He then reunited Vella and Tyzonn and now under the care of the Hartfords.
