This is a 2-part Season premiere.

Speed Boost was on the train alongside Lightning Bolt and their daughters, Supersonic and Blue Streak."Where are we going?" asked Supersonic. "You'll know soon enough" said Lightning Bolt. The pegasus took out her Game Pony and began to mash the buttons. "Come on" Supersonic mumbled. She started pushing them harder and harder. And harder. And hard- HISS! The Game Pony was smoking. In a rush, Supersonic threw it out the window. "I told you that thing wouldn't survive much longer" said Blue Streak. Supersonic rolled her eyes. "Whatever" she said. Her sister was one of the most annoying sisters you could imagine. Supersonic looked at her flank. Her cutie mark was a lightning bolt with wings. She kept pondering the thought of why it looked that way. Until the train stopped. "Stop your daydreaming, it's time to go!" said Blue Streak. "Huh? What?" Supersonic had not realized the train stopped or that she was daydreaming. They walked out of the train. "Is that-SUPERSONIC!" Breakneck hugged Supersonic. Supersonic chuckled. "And who are you?" Supersonic asked. Speed Boost interrupted."She's your cousin, Breakneck." Supersonic walked out of the train. "You're not coming with me?" she asked her family. "We'll see you later, sweetie." said Lightning Bolt. "Bye Super-" Blue Streak was stopped by the train's noise. "I guess I should look around." Supersonic said to herself. She was walking for a while, but she soon bumped into someone. He was a handsome stallion. Supersonic noticed his cutie mark. A sonic rainboom. "Sorry!" she said. Supersonic walked off. "Hear ye! Hear ye! The Accelerania Race will begin in ten minutes!" "What was that?" Supersonic said. "Hey, maybe I could race!" she said to herself. So she went to the race. Supersonic was accepted into the race. She was soon at the starting line. "3...2...1...GO!" Supersonic was winning. Her cutie mark was glowing. She went faster and faster and faster until-It happened. She was in an empty space. Blue and empty. Then a figure approached her. It was Princess Lightning Strike. "P-princess?" "I thought you were gone" Supersonic said. "That doesn't matter now" said the alicorn princess,"You have finally proved yourself to be the heir to the throne." "Wait, does that mean-" "Yes, Supersonic. It does mean you'll be an alicorn princess too." "Now, you must get back" "Wait, princess! PRINCESS!" Supersonic appeared back in the race. She was taller. She had wings and a zebra pattern. Her hair was spiky. Supersonic was an alicorn princess! Plus, she was faster than ever. She won the race. She was so happy. But she was interrupted by a figure looking over her. "I AM STRIFE, AND I WILL RULE ACCELERANIA! MUHAHAHAHAHAHAHAHAHAHAHAHA!"

I'll release Part 2 if there's enough reviews telling me to continue. Also, guess who Strife is? Anyways, hope you enjoyed the first episode. See you next episode! Bye!
