Chapter 4
The group was in the mystery shack.
Mabel: Dipper. What happened to you out there? You took down that big Xenomorph like it was some kind of trophy.
Wendy: And you treated the smaller ones like you were hunting them.
Soos: And to top it all off, when you killed that thing, you did that weird victory roar, and kept it's head as a trophy.
Dipper: It's the armor I'm wearing. The longer I keep it on, the more like the Yautja I become.
The news came on.
Reporter: This is Toby Determined of the Gravity Falls news. Gravity Falls is being attacked by strange alien monsters. They're attacking everybody here!
The camera cut off.
Dipper: You guys stay. I'll take care of those guys.
Stan: We're a family, Dipper. We do this together. We can use my guns.
Everybody picked up one of Stan's shotguns and loaded them up.
Dipper: Alright. From here on out, nobody leaves this group. We stick together and we take on this enemy together.
He made a rapid, guttural clicking noise.
Mabel: Dipper, you're starting to sound weird again.
Wendy: And you're skin. Look at your skin!
Dipper looked down and saw his skin was more reptilian than normal. It had a beige-green hue to it. The most noticeable change was his hair. It had been turned into tendrils hanging over his head that looked like dreadlocks.
Stan: We have to kill every last one of these before it's too late.
Dipper did the clicking noise again, having lost the ability to humanly vocalize.
Mabel: Oh no. He's so alien, he's forgotten how to talk like a human.
In Dipper's mask, he played back that sentence, and mimicked it to Mabel's exact voice.
Dipper:"Oh no. He's so alien, he's forgotten how to talk like a human."
Soos: Ha. He can mimic people. That's cool.
Dipper gestured the group forward as they ran through the darkened streets of Gravity Falls.
Out in the city, large groups of Xenomorphs were running rampant through the city, killing everyone mercilessly. Dipper and the group arrived and attacked the Xenomorphs. Dipper used a combination of all of his weapons to kill them. He blasted one with his plasma caster, cut up two with his shurikens, beat another down with his combi stick, decapitated another two with his wrist blades, and blasted the last one with his plasma caster.
Stan: This is still Dipper, right?
Wendy: Honestly, I don't even know anymore.
A bullet suddenly hit Dipper in the body. His eyes darted to the right, and he saw Wendy's father, Manly Dan, standing there armed with a revolver.
Wendy: Dad?
Dan: Wendy! Get behind me while I kill this thing.
Wendy: Dad. That thing has been keeping us safe.
Dipper slowly approached Manly Dan, getting hit by multiple revolver bullets that bounced off of his armor. He grabbed Manly Dan by the throat and pinned him to the wall with one hand. He pulled out his wrist blades from one hand, preparing to kill Wendy's father.
Wendy: Dipper, stop! Don't do this!
Stan: The Dipper I know isn't some heartless murderer.
Soos: Don't do it, man!
Mabel: Just because you turned into one of them, doesn't mean you are one of them!
After hearing this, Dipper dropped Manly Dan on the ground and let him escape. He then growled as his eyes darted to the group. His body disappeared as his eyes flashed a yellow color.
Wendy: Where did he go?
Soos: I think we made Dipper mad.
Stan: He's going to kill us all! Run!
The whole group ran as Dipper stalked over them, looking at them through his thermal vision. He pressed some buttons on his wrist bracer, which sent a signal to the Yautja home world.
