17 parts Complete Alias is an unusual girl. She doesn't remember who she was when she was younger, her first memory was as a 6 year old, stumbling through the woods into an old abandoned barn, wounded and weak. This is where she meets the equally confused Cybertronian, who she named Nickname. As they grow up and learn about the world around them, they realize that the world is a horrible place.
And while Nickname has the Decepticons chasing him, Alias has a group of human sized metal warriors that seem endless and relentless chasing her. (Later revealed by Ratchet as power hunters from early Cybertron.) Oh, and did she mention her metal wings? No, oh well...
Once they meet the Autobots though, they seem to have found their peace, until they decide to help the Autobots of course. I mean, after Alias tries to kill them. Megatron isn't a very nice fellow per usual, and he had already stumbled upon the bounty hunters chasing Alias and claimed himself their lord and master.
