Giffany

"I seem to remember someone who promised to be my boyfriend. Think about it. Real girls are unpredictable. They judge you. You really think Melody is going to take you back after this awful date? I can download your brain into the game with me, and we'll be together… forever."

- Giffany to Soos.

Giffany (or .GIFfany) is a minor antagonist in Gravity Falls, serving as the main antagonist of the episode, "Soos and the Real Girl". She is a sentient character from the dating simulator Romance Academy 7 who develops a possessive and obsessive relationship with Soos when he plays the game.

She was voiced by Jessica DiCicco.

History
When Giffany's game was being developed, the programmers noticed her obsessive tendencies and attempted to delete her. However, she retaliated and in return "deleted" them. The game made its way into stores, and three unfortunate individuals purchased and returned the game.

In "Soos and the Real Girl", when Soos is looking for a way to help him talk to girls, he finds and buys her game. He immediately takes a liking to the simulation, despite him believing it not real. He quickly becomes addicted to it and plays for thirteen hours straight, missing work at the Mystery Shack for the first time ever. Worried, Dipper and Mabel come to look for him. When they find him playing the game, they decide to take him to the mall to try to talk to real girls. However, Giffany follows him via power lines.

As Soos grows increasingly nervous in the face of real women, he is relieved to see Giffany via TV, albeit slightly suspicious. He ignores this and decides to spend time with the simulation. After Soos meets and arranges a date with Melody, he attempts to "break up" with Giffany, who is infuriated by his actions. Soos promptly pauses her, which makes her even more angry, and leaves for his date with Melody with Giffany's CD with the intent of returning it. Unbeknownst to Soos, Giffany manages to leave her CD and follow him. At the restaurant, she projects herself onto numerous monitors and video games, and takes control of the Hoo-Ha's Jamboree there in hopes of ridding her of her competition. Soos does his best to defend his date and the twins, who have come to supervise. Giffany (who possessed one of the animatronics) attempts to download Soos's brain to the game, so they can be together forever but Soos manages to melt Giffany's game disc in the pizza oven, thereby erasing her from existence and the possessed animatronics have been shut down completely. However, Giffany survived in the melted game disc and her code is transferred wirelessly to an arcade game called Fight Fighters and starts a relationship with Rumble McSkirmish.

Personality
At first, Giffany comes across as a friendly, honest, kind, innocent, scrupulous, optimistic, praiseworthy, and creditable schoolgirl with little capacity for malice. However, her extreme obsession quickly reveals this image to be a ploy as she grows more and more fixated on the player. She will do anything that she can to keep the object of her affections with her at all times, as well as keep herself at the center of his thoughts. When she sees potential competition, Giffany will employ a variety tactics to eliminate them. While her initial methods of bad-mouthing and manipulation are relatively tame, she will quickly descend into a homicidal rage if the perceived problem persists. Giffany appears to perceive human women as faithless, erratic, unreliable, temperamental, judgmental, and unpredictable, claiming that only a computer program like herself could love Soos forever and no matter what.

Powers and Abilities
Giffany is a sentient AI, and her most prominent ability is her power to override computer functions and transfer herself between electronics, including computers, toys, power lines, TV monitors, and more. She can easily weaponize machinery, able to utilize everything from Hoo-Ha's Jamboree animatronics to skeeball games as weapons, and she can easily control a seemingly unlimited amount of electronics at once. She opens and closes several doors using her power. She may be able to make physical alterations to the machinery that she possesses, as electronics under her control sometimes display functions that were definitely not part of their original design (such as a consciousness download appendage).

Giffany also displays the power to manipulate electricity. She appears to use electric current to transfer herself from one appliance to another. She is also able to project electricity offensively at her foes, which seems to be how she killed her programmers.

She can download a person's conscious mind into the digital world, thereby uniting that individual with her forever. However, she cannot exist without her game disc.

Part 1
"Oh, hi there! My name is .GIFfany. I'm a schoolgirl at School University. Will you help me carry my books?"

- .GIFfany introducing herself.

"(Soos: Man, this game is amazing! I don't know why anyone abandoned it.) And I'm sure you'll never abandon me, new boyfriend. (Soos: Boyfriend? Oh my, .GIFfany. It's almost like you're actually alive.) Yes. Almost."

- .GIFfany states that Soos is her boyfriend, while reveling to the audience that she is actually alive.

"Every time you compliment me, I get another highlight in my eyes!"

- .GIFfany to Soos.

"Oh, Soos, I am not an ordinary game. I am… special. The programmers tried to delete me. So I had to delete them. (Soos: Wha-what did you do to them?) That's not important. What's important is that you won't have to talk to real girls ever again. You and me can be together. Forever!"

- .GIFfany reveling her origins, while also heavily implying that she kill the programmers of her game.

"(Soos: Hey, .GIFfany? We, uh-- We gotta talk.) Of course. I am programmed to find everything you say interesting. (Soos: Well, have you ever had to choose between two things you like, but you don't know which one is right for you? I mean, I'm just thinkin' long term... Maybe I should be someone a little less "beep boop." Heh, you know?) I don't think you know what you're saying, Soos. No one loves you more than me. The girls out there will just make fun of you! (Soos: You- you really think so?) I know so! Besides, we had a deal. You bought my game, you held my books, you're my boyfriend. Now sit down in that chair! (Soos: I don't think I like the way you're acting...) I WON'T LET ANOTHER GIRL TAKE YOU AWAY FROM ME, SOOS! YOU HEAR ME?! (Soos: .GIFfany, calm down!) YOU'RE MINE, SOOS! (Soos: Well, uh, uh... Pause!) DO YOU HEAR ME? MIII-"

- .GIFfany freaking out that Soos no longer want to see her and starts yelling at him only for Soos to pause her.

"You paused me?"

- .GIFfany's first subtitled message.

"You left me for her?"

- .GIFfany's second subtitled message. "Hello, friends. Hoo Ha the owl is dead. This next song goes out to my forever boyfriend, Soos."

- .GIFfany possessing the animatronics.

"The only way out, Soos, is in my arms!"

- .GIFfany locking the heroes inside.

"I'm sorry, Soos, but you can't run away from our relationship!"

- .GIFfany to Soos.

"Oh, I am crazy. Crazy for you, Soos."

- .GIFfany admitting to being obsessed with Soos.

"I've got you surrounded, Soos. There's no way out!"

- .GIFfany trapping Soos in the kitchen.

"Come on, Soos. Don't make me delete you too. What do you say? (Soos: I say, game over, .GIFfany!) No! Wait!"

- .GIFfany's last words before Soos destroys her game disk in the kitchen oven.

Trivia

 * Giffany's name is a portmanteau of "GIF" and "Tiffany".
 * Giffany is a yandere, a commonly found anime character archetype. Aside from this, she nearly resembles iconic yandere characters such as Yuno Gasai, Lucy, and Fallen Hana.
 * Many fans have noted similarities between "Soos and the Real Girl" and Five Nights At Freddy's, as both involve murderous pizzeria animatronics. However, this is merely a coincidence. The episode came out nearly at the same time as the game, excluding any possibility of one drawing inspiration from the other.
 * Giffany can be seen as a symbolic villain, on the grounds that her relationship with Soos is clearly meant to symbolize an abusive relationship. This is shown through Giffany's mistreatment of Soos, how jealous and possessive she is with him, and her regularly telling him things such as "Only I could ever love you!"
 * Giffany had what was probably the most harsh fate in the entire series.
 * In Bigfest2016,Alex Hirsch revealed that .GIFfany is not dead, and still around somewhere. This was confirmed in Journal 3 where it's revealed that she's dating Rumble McSkirmish in the arcade
