"They always know what they are: a wicked Decepticon or an honest Autobot, deal with it so they can decide what to do without doubt." A/N: This's a fanfic of Transformer, it's based on cartoons and comics. I'm Vietnamese and a big fan of Transformers. I wanted to write this fanfic long ago in Vietnam's language, yet there aren't much Vietnamese who would like to read it. So i decided to write it in English for the foreign fans of Transformers. However, my English skills are not good enough, i'm in the process of learning and have to practice more so if i do some mistakes, just tell me, i will correct it. I do not own any characters of Transformers. If there are any names that you don't know, they will be my OC.

After being killed in the crossfire of an Autobot vs. Decepticon battle, the young girl's body is taken by MECH and is reborn as Ace (Altered Cybertronian Experiment)

"There was thirty seven Primes, only thirteen survived the battle against Unicron. Now only two Primes remain and I am one of those two..." Perhaps the Great Cataclysm didn't offline every Predacon. Perhaps those Predacons are thriving in secret. Waiting for the right moment to correct a devastating error made by transformers war. The question is what are they waiting for?

Stay: Book One Tracy was normal. Human. No creepy special powers unless you counted her ability to turn situations around in her favor. But she won't be normal for long. She became special when she volunteered to give up her life as a human and become . . . an Autobot? One day leads to the rest of her life going from normal to extraordinary, and her bonds with the Autobots, one in particular, will be what gets her through the challenges thrown in her path, like when she is forced to face off with Megatron time and again. It's a deadly path she walks, and danger threatens her every move.
