The Everfree was unnatural. Even though there are vicious monsters, they can be easily pacified, expert animal tamers like Fluttershy feel it’s a piece of cake if they were ever told to. However, those things are nothing compared to the ones made in metal.

One day, Daring Do was exploring the Everfree Forest, leading her much deeper and into the swamps, and saw a 33-foot tall thing standing above a dead hydra. With this knowledge, she has contacted the Mane 6 for help.
Another adventure awaits for them.

This will be intense for her and the others.

Added "Alternate Universe" tag. Because this happened when the Decepticons got the Allspark (TF: The Game, Decepticon Campaign).
