Nightmare was always the one wolf among the Autobots back on Planet Cybertron, and well, she became one herself. Knowing full well that she is loyal to Optimus Prime for the rest of her life. Besids Boris, the were goose of course.

Nightmare is known as a wereformer, a wolf melding into a transformer whenever she transforms of course, and not mentioning the fact that she is also a legendary Prime as well.

Not many knew why she was a wereformer and a legendary Prime as well, save for Optimus and the Autobots. She knew that she had to find them and join their ranks to keep up with her training and to keep them and the humans safe as well.

After getting to Earth after the Mini-cons came back online, both Boris and Nightmare had gotten separated from the others, but at least they would have a trail to follow when she heard fighting off in the distance.

The kids, Rad, Alexis and Carlos were just trying to stay out of trouble when the two wereformers arrived on the scene with Hotshot asking,"Hey, what happened to you 2? Get lost along the way?"

Nightmare snorted as she replied with,"Don't get me started Hotshot. I've about had it up to my teeth from hearing it from Mr. Nerves over here. Besides, we're back aren't we?"

Boris went to where the kids and the 3 active mini-cons were and stayed put while the fight went on for a few moments while the wolf went crazy against Cylonus a bit till there was a landslide and Hotshot along with Red Alert protected the kids and mini-cons.

Nightmare's ears were laid back while she dealt with Starscream after dealing with the one she was fighting at the moment till they retreated after the kids found more mini-cons and two went to the Autobots.

She howled after the fight ended and Cylonus brought at least one mini-con back to the Decepticon base. The goose calmed the wolf down enough till they all went back to base to meet the kids and to introduce themselves.
