The Wraith Equestria Girls

As the convoy and the cars went to find Sombra, they have searched far and wide block after block but no sign of him at all. The groups then rallied to each other and discussed their searching.

"Anything?" asked Wraith.

"We looked uptown and he wasn't there" said Max.

"We looked downtown and we did not find him" said Christine.

"Well we need to keep looking he could be anywhere" he said

"I agree, we cannot allow him to make his own throne here like Nightmare Moon did" said Starlight.

Then there was evil laughter surrounding them. They jumped in shock and fear as they heard it. Then a pair of yellow headlights appear and rolled forward to approach the group. It was none other than King Sombra himself as a Chevy Corvette glaring and staring at them savagely.

"Hello Princess, it has been a while, and Wraith it is a surprise to see you here" he said.

"What do you want Sombra!?" asked Twilight.
"After my defeat by you with the crystal heart and by Wraith, I’ve had a plan to rid you and your new friends out of my way to begin my new rule here" he answered.

"You're not taking this world from us forgranted. We will not surrender to the likes of you at all in any way. Because we are not afraid of you!" said Max.

"You think that you can resist me? Well I will see to that as soon as I prepare myself and raise another army with the scrapped machines you all destroyed when you're in battle with Nightmare Moon" he said as he used his dark magic to resurrect the destroyed machines as they awake as undead machines.

"I'll give you a few days for you to decide to surrender, if not you will all perish" he warned.
"You will not touch my friend from a farm you varmit!" yelled Pete.
"We will decide but be warned, the darkness will not always be your strength" Trinity warned as the convoy and the gang left the city.

"It is only a matter of time before my new throne is made and you will all bow to me" he said as he watched the convoy drive away.
