Impostra was one of those among Scorpius' corp that looted Magna Defender's planet and witnessed his son's demise. She disguised herself as Treacheron to trick Destruxo and frame Treacheron. Impostra wanted to take the Lights in her urn but Magna Defender destroyed her urn. Magna Defender blasted Impostra, she claimed she would be back but she was never seen again.
