Shatterspark

During the war the decepticons started to create more soldiers to fufil their needs. Stallion and Shatterspark were two of these bots created, they trained together and quickly became fast friends and later lovers. Throughout her training as an intel scout Stallion began to question the methods of the decepticons and slowly started secretly delving into the autobot cause. On one of her missions she came face-to-face with Optimus and was able to covertly strike a deal to extract both her and Shatter from the decepticons. The infiltration goes wrong however and only Stallion is able to make it out but she vows to find a way to return for Shatter.

After Stallions abrupt leave, Shatter feels betrayed, convinced her lover abandoned both her and the decepticon cause. This betrayl is further exacerbated by the decepticons, convincing her that Stallion had been an autobot spy and only used her to gather resources for the autobots. The decepticons use her place of hurt to make her into an even better weapon, taking her apart and rebuilding her until they are satisfied with the perfect destroyer. Shatter becomes indespensable in battle, earning her full name for her penchant to go straight for the spark, forcing her claws through metal until it breaks.

Meanwhile Stallion has never stopped looking for her, after the invasion the decepticons secretly moved base but that didnt deter her. She still remains allied with the autobots, using her job as a bounty hunter to gather info for them while she looks for Shatter. Eventually Stallion is able to find her but she immediately goes on the attack. Stallion doesnt want to hurt her but she knows she has to put in her all, Shatterspark is bloodthirst and she remembered how dangerous she was in her academy days, even more now. Shatterspark is full of grief and rage when she sees her again, because despite after everything she still loves her...

I will figure out their ending later... disclaimer: none of this is canon compliant as of rn bc im still new to the fandom
