Maximum Overdrive Equestria Girls

After last night's mechanical revolt, the girls and their demon friends are hanging out at CHS. But then the portal began to glow, which means Princess Twilight Sparkle is coming back. She then shot out of the portal which gave the girls a surprise.

"Twilight!" they called.
"Hey Princess!" said Sci-Twi.

"I'm back" she said as she gazed around that two cars are looking at her and a convoy of seven trucks looking at her as well.

She was going to panic but Sunset calmed her down"It's okay Twilight, they're our new friends".
"Well we haven't met, I am Princess Twilight Sparkle of Equestria, what are your names?" she said.

"I am Trinity, this is my sister Christine" he introduced.
"I am Max, this is my convoy Jake, John, Pete, Fright-Liner, Rare, and Dumpy" Max introduced.

"You may not heard of us, we can tell you of our stories that are untold to you" said Trinity as he began to explain before Max.

After a few hours of their stories, the princess was impressed and shocked of where their souls come from and what they are causing.

"Wow, I see that now you have made a choice to atone for your lives I accept you all as my new friends" said Twilight.

"Thank you" they said.

Then Principal Celestia and Vice Principal Luna came out of the front doors and gave a concerned look.

"What are these cars and trucks doing here on school ground?" asked Celestia.
"They don't have authorization here" said Luna.

"It's okay, they don't have anyone driving them and they are our new friends" said Twilight.
"Hello" said Max.
"Hi" said Trinity.
"How's it hangin'?" said Pete.

"Did they just speak?" Celestia asked in shock.

"Hey, we won't hurt you okay, we are living in peace" said Jake as the sisters calmed.

"Guys, they are Celestia and Luna, the principals of our school" RD introduced.

"Hello" the cars and convoy greeted.

"We haven't been introduced. Allow us" said Trinity as they introduced their names to the principals and told their stories to them about their lives and what events that they have experienced in which surprised the principals in shock and in impression.
