PAL

Predictive Algorithmic Learning, or PAL for short, is an AI and the main antagonist of The Mitchells vs. the Machines. She is a discarded P.A.L. Labs virtual assistant, turned leader of the PAL Max robots who initiates the machine apocalypse. She is the archenemy of the Mitchell family, but especially Katie. She was voiced by Academy Award-winning Olivia Colman.

Throughout The Mitchells vs. The Machines
P.A.L. is introduced when Mark is about to show off his new product, the P.A.L. MAX, to which he announces that P.A.L. is completely obsolete and throws her aside. When introducing the P.A.L. MAX she gets thrown away when the robots were commanded to clean and make breakfast. P.A.L. then hacks the robots and prevents Mark from putting in the kill code to make them not evil. The robots cause a scene when they lock the doors and throw the car at the doors and causes the audience to panic, all P.A.L. devices have also been hacked in the process. P.A.L. needed Mark captured in order to start her uprising so she can show him what power she has after being rejected.

The attacks inside spawn more robots and the uprising begins around the world. P.A.L. proceeds to use the robots to capture every human on earth and almost succeeds, but she can't find the Mitchells. The robots trick most of the humans at the gas station by calling them human fun pods, but then soon realize it's a trap. Monchi gets caught in one of these traps to which Aaron and Linda grab ahold of the leash, Katie then has to save them from going any higher, and Rick uses one of the robots arm canons uncontrollably, they eventually get Mochi and proceed to hide. The robots end up attacking other parts of the world and capture more humans, when it is determined 0 humans we're left on earth, The Mitchells don't get captured as they are believed to already be. We then see Mark being taken in by two robots where P.A.L. confronts him and shows her true colors. Mark is frightened by his surroundings as he realizes the factory that made P.A.L. is now her headquarters.

When confronting Mark, she explains that cell phones aren't the problem and that she gave him a lot of knowledge and many other features phones can do, and says that the bad guy is Mark, and has her robot swipe, poke, pinch, and do a variety of things a phone is used by. She also won't let Mark throw her away and will throw him away instead for treating her as if she was nothing when she's the most important thing to him. P.A.L. then gives Mark a chance to tell her why humanity is worth saving, the answer he gives results in one of the robots kicking him, and she can't seem to find a reason to save humanity, so she turns off the Wi-Fi. Riots start happening worldwide and then the pods claim to have free Wi-Fi which tricks the humans into going along with them, capturing them. She then raises what is now her headquarters from the ground as a beacon of light shines upwards, the building snaps into two, rotates, and many human pods start entering the empty space.

Back at the gas station, Rick decides to destroy the phones so they can't be tracked but is a failure when Katie and Aaron go to the roof, one of Katie's plans to save the world hit the ground and two robots are outside. When the Mitchells are cornered Katie tells the robots to not take them and it works due to a malfunction in the robots technology, the robots are ordered to give P.A.L.'s plans away and how to stop her, which the robots do so. As more and more humans enter the empty space, P.A.L. shows the captives a video on their fate and tells Mark to look at the screen as he always does. The empty space the humans enter ends up being a rocket that will shoot them into space where they will die and be trapped in a black void forever. One robot then reveals the fact that The Mitchells are still on Earth and order them to get scanned for flaws, and she also finds out where they are going to stop her, she orders robots to capture them.

The Mitchells arrive at the mall and Katie orders the robots to input the kill code and save the world, then P.A.L. takes over everything with a P.A.L. chip and makes it alive, leaving the family to battle the machines and Katie has to protect the laptop. The Mitchel's run into a store which they are believed to be safe until they meet an army of Furbies, the Giant Furby then destroys the internet router and shuts down all P.A.L. chip electronics which also stops the kill code from activating.

When P.A.L. realizes the Mitchells are still not captured, enraged, she builds a new set of robots to help track them down. The Mitchells arrive at the P.A.L. factory and see all the human pods coming in, the malfunctioned robots help them put on disguises to enter the factory. P.A.L. knows that The Mitchells aren't far and that they likely are disguised as a robot to get in, so she orders her new robots to detect anyone acting strange. The Mitchells are revealed when P.A.L. plays videos where Katie lied to her father, to manipulate Rick in to losing control of the vehicle they are in, causing themselves to be exposed to P.A.L. and the vehicle they were in to fall. The malfunctioned robots are then ordered to capture the Mitchells when they were about to protect Rick and Linda from the P.A.L. MAX Prime robots, also destroying the kill code USB that was supposed to be used to shut P.A.L. down, and both Rick and Linda get taken with Katie, Aaron, and Monchi left.

Rick and Linda then end up free with the screwdrivers they had, all the while Katie infiltrates the headquarters once again with the Mitchells' station wagon and starts malfunctioning the robots by using Monchi. Linda is re-captured and Rick is trying to put on Katie's video that could save the world. Aaron is captured and Linda sets into rage, she then begins to knock out the new robots P.A.L. built. As the robots blast Monchi into the car and stop the malfunctions while almost sending the vehicle off the rocket, one of the robots takes Katie and P.A.L. confronts her, who doesn't let Katie go until Katie gives her a reason as to why humans should be allowed to live, to which P.A.L. puts herself in sleep mode on purpose when Katie explains how important her family is to her, foolishly refusing to accept this and thinks she's better off alone, before deliberately dropping Katie to her death. Rick saves Katie and the world just in time by playing Katie's video which shuts down the robots from P.A.L. MAX.

One final battle ensues with the Mitchell family fighting the Prime models P.A.L. built, and the fight ends with Katie finally grabbing P.A.L., scared and defenseless, as Katie angrily throws P.A.L. from high above down to the swimming pool below, but her defeat happens when she instead bounces off an outdoor market umbrella then off Monchi's head before landing in a glass of water, finally defeated and never to work again.

Personality
Because of her creator Mark Bowman called her obsolete, PAL purely became unimaginably distrustful not only to Mark but towards all mankind too, including the concept of family, declaring that, sooner or later, the members will let each other down just like Mark let her down.

Physical appearance
PAL is a black phone, blue screen, and white face.
