Before, she was Elita-1, an energetic, spunky Autobot cadet. Until a fateful trip to Archa Seven, where she fell victim to a horde of mutated alien spiders. Now calling herself Blackarachnia, she hates her new body with a passion. Her loathing of her organic parts is slowly driving her insane, and she will do anything to get rid of them, no matter who she has to crush in her path. Her mutation fueled a newfound hatred of Autobots, and she joined up with Megatron. She transforms into a spider.
