|This article is about a/an monster in Power Rangers Lost Galaxy.|
Impostra was a Medusa-themed, shapeshifting monster.
She was one of the many monsters among Scorpius' army that attacked the Magna Defender's planet and witnessed his son's demise. Called into service by Trakeena, Impostra disguised herself as Treacheron to trick Destruxo, and frame Treacheron, all at once.
Impostra wanted to take the Lights from Destruxo, and trap them into her urn but the Magna Defender intervened, destroying her urn with his Magna Blaster. Magna Defender shot Impostra out of the tree. Pulling herself off the ground, she claimed she would be back, however, she was never seen again.
- Unlike her Sentai counterpart, who was destroyed by Treacheron's Sentai counterpart fter he learned that she has framed him, something that Treacheron never done, she only disappears.
