Transformers: The Emberspark

It was the last days of the devastating War of Cybertron. The planet was dying, unable to sustain its inhabitants much longer. The noble Autobots, with no other options left, seeks to activate the legendary Ark, a Vanguard-class Deep Space cruiser, able to transport billions of Cybertronian civilians, hoping to use it to evacuate every Cybertronian from their dying home.

Ashbreaker, an inventor, initially wants nothing to do with the war, wanting to live a life with her inventor friends away from the Autobots and the Decepticons. However, that all changed when the infamous Decepticon Justice Division attacked her lab, slaughtering all of her friends in gruesome ways.

Ashbreaker was the sole survivor of the carnage, broken and left for dead, until she was rescued by Autobot medics. Now left with nothing but her hatred for the DJD, she joins the Autobots with only a single purpose in mind: to scrap all the Cons responsible for the deaths of her friends.

Meanwhile, she joins an Autobot black ops squad known as the Emberspark, with the members have nothing left to lose and a mission: secure the codes required to activate the Ark, with them serving as the last hope for the Autobots and all of Cybertron.
