After Twilight's failed attempt to summon Starswirl and his companions, Rainbow just tried to forget about everything, and flew towards the Wonderbolt Academy. It was far away from the temple, but nopony called her "the fastest pony in Equestria" for nothing.
So, with not a single help, the Pegasus flew fast, facing her new destination. However, when she got half of the way, she started feeling strange, until realizing she was flying significantly slower than before.
"What the hay? Did Twilight do something to me or what?" Rainbow asked for herself.
As she wasn't going to receive any answer at that moment, she decided to just keep flying.
At the academy, Spitfire was watching the Pegasi as they tried to make some stunts they were practicing. Some time later, Rainbow arrived, landing next to Spitfire with a tired expression.
"What happened, Dash? You usually don't get too tired before coming here," the Wonderbolt leader asked.
"I don't know! I was flying fast, and the next minute I wasn't doing that! It has taken me even longer to come here!" Rainbow answered.
Spitfire doubted about what she heard, but Rainbow was clearly exhausted, "Well, I guess you could get some recovery inside the changing rooms."
"That would be so awesome," and the cyan Pegasus walked away.
"Well, here I am: the fastest pony in all of Equestria, unable to fly faster. Could this get any worse?"
Just as Rainbow pronounced those last words, she noticed something different: her wings wore another color. It wasn't cyan, and it wasn't blue either. Instead, both wings looked more... yellow.
"Ok, this is the craziest thing I have ever seen," Rainbow said, her voice sounding in a lower tone "Uuuuh... And this may be the... second craziest thing?"
Rainbow's athletic body went through a list of changes, the most considerable one being that she turned into a stallion. As for the colors, the amber on her wings extended to cover all of the fur, and her eyes turned blue. The colors on her mane and tail changed to just a moderate amaranth and then, the final details appeared.
A few bruises emerged on the wings, and some kind of armor, complete with a helmet and a red cape, covered her body, along with some piece of the armor getting put on one of her hooves.
In a matter of seconds, there was no other sign of Rainbow Dash than just her mind. And of course, she was freaking out.
"What!?"
"Sir? May I ask who you are?"
Rainbow turned to the door, spotting Spitfire as she stared at what she thought to be a different pony.
"Huh... It's a long story..."
