In another life, she was Elita-1, an energetic, spunky Autobot Academy cadet. However, a fateful trip to an alien world saw her teammates abandon her to a horde of alien spiders. The accident changed her psychically. Now calling herself Blackarachnia, she hates her new body with a passion. Her loathing of her organic half is slowly driving her insane, and she will do anything to get rid of it, no matter whom she has to crush in her path. Her mutation fueled a newfound hatred of the Autobot cause and a quest for revenge that led her to join Megatron in his war against them. However, she does not appear overly loyal to her leader.
