In the future, Equestria has been overrun by Changelings including the Mane Six who have been converted by Chrysalis. One hero must defend what is left of Ponykind and build a new future.
"What do you mean?" Lime asked, suddenly more scared than ever. "What about this will put my town at risk?"
"You're a Changeling, Changelings seek out the hive," Scarlet answered. "And eventually, that instinct will become too strong for you to overcome. You may hurt your friends and family as a result, or if they find out they will throw you out or worse. Please Lime, we just want you with the Hive where you belong. It's what's best for everyone."
Hajime can empathize.
...Should we call the Black Joker into this universe to clean things up a little?
"Get out of this town and never come back," Sea said as she brushed herself off. "I'm not going to have more blood on my hands than necessary. I can finish you off here, but I'm not going to. Get out of Appletown, or I will make sure you regret not leaving."
Run away Scar(Let). Run away, and never return...
But seriously, I like her. She's a Changeling, yes, but she seems like a perfectly reasonable sort. Even saved Lime's life.
"Ah... I see you must be Elusive then," a feminine voice said happily. "You have such a lovely mind. What can I do for you? What is your greatest wish?"
"I..." Elusive said and paused a moment. "I want to create, I want to be able to make beautiful things and give them to the world. That's my greatest wish right now, the Hive could do so much more with what we have."
"Then your wishes shall be granted," the insect said as it started to glow with magical energy.
Corrupted Generosity. Oh, so we're going here again eh?
As the familiar armor formed over Sea Spray, she looked at Elusive expectantly.

Back in the lab in the Resistance base, Tinker had gotten back to work on the Guardian Driver. Ever since she had found out about what was happening to Sea Spray, she had felt like it was necessary to get this done even more.
As she worked on connecting the conduits of the magitek system, she testingly applied some of her own magic to it. The Driver was made to work on pony magic similar to how the Change Driver worked on Changeling magic.
Finally, sparks of magical energy flew between the connecting wires as she finished. A gold and white stone started to shine with an unnatural energy through the wires and she smiled.
It was done.
...Okay, now this is interesting... Secondary Rider perhaps?
