According to Toy Story producer Ralph Guggenheim, John Lasseter, and the story team for Toy Story reviewed the names of Pixar employees' children looking for the right name for Woody's owner. Andy was ultimately named after Andy Luckey, the son of legendary animator Bud Luckey, Pixar's fifth employee, and the creator of Woody. The younger Luckey in interviews has claimed he wasn't aware that he was the namesake of the character, stating in Animation magazine that he believed it to be an urban legend and that he had assumed the character to have been named after Pixar animator Andrew Stanton.
Andy has fair skin, brown hair, and blue eyes. In the first two movies, he wore a red cowboy hat, which he stopped wearing prior to Toy Story 3. At the beginning of Toy Story, he wears a green t-shirt with a cowboy playing the guitar on the top right corner, blue shorts, white socks, and white sneakers with blue laces. When he goes to Pizza Planet, he wears a purple polo shirt but keeps his blue shorts. On moving day, he wears a light blue t-shirt with light brown shorts. However, He wears his original outfit in a shot where he sadly leaves his old room holding his hat and Buzz's box, but this could either be an error, or he slept in those clothes. He is seen in two sets of pajamas. They both consist of white short-sleeved raglan shirts with colored sleeves, shorts, and white socks. His first set is yellow with a cowboy on the shirt, and the other is blue with Buzz Lightyear on the shirt.
In the first part of Toy Story 2, he wears a white t-shirt with the bull-headed logo of Triple-R Ranch, dark blue cargo shorts, and grayish-blue sneakers. When he returns from Cowboy Camp, he wears a dark green t-shirt with gray cargo shorts and the same color amount of sneakers.
In Toy Story 3, Andy, now a teenager, has developed freckles and grew out his hair into messy bangs. He now wears a blue t-shirt with darker blue trim, blue jeans, and gray and brown sneakers. In the end, he wears a blue dress shirt with a white undershirt, but his jeans and sneakers remain.
In the flashbacks at the beginning of Toy Story 4, Andy appears as a kid again, but a few years older. He is seen wearing a blue baseball t-shirt with white sleeves and a darker blue border, blue jeans, and black converse sneakers. In a couple more flashbacks, he can be seen in other blue shirts: one with stripes, and another one that is similar to the shirt he wore in Toy Story 3.
As a child, Andy is portrayed as being an eager, imaginative boy who lives with his mother and younger sister Molly; his father is never seen in the films. He is 6 years old in his debut and is the owner of Woody, Buzz Lightyear, and the other toys, which he treats with a large amount of love.
As a teenager, Andy's personality changes drastically. He is now portrayed as being a gruff, easily irritated, and lethargic seventeen-year-old, but still a kind and compassionate person. Though he no longer plays with his childhood toys, he still cherishes them because of their importance to him as a child and finds it hard to let them go with Bonnie, especially when he found Woody (who had the same problem with his owner) inside the box.
In Toy Story, Andy and his family are preparing to move to another house the following week, so his mother decides to hold his sixth birthday party a week earlier, during which he receives a Buzz Lightyear action figure as a gift, causing tension between Buzz and Woody, who has always prided himself on being Andy's favorite. He spent much more time with Buzz and grew to love him as much as Woody, but he still held a special place in his heart for Woody himself, as evidenced when both toys went missing for a time and he fears they would be left behind after he moved to a new house with his family, when, unknown to him, Woody and Buzz are in Sid Phillip's house. Fortunately, he is able to find them as they are driving to their new house after he discovers that they were in the car the whole time (by that time, Woody and Buzz have put all tensions aside and become friends). Later that year during Christmas, he receives a puppy, though his bond with this new pet is never developed beyond his excitement about having one.
In Toy Story 2, four years after the events in Toy Story, Andy is now 10 years old and is seen only at the beginning, and for a short while at the ending. However, during the short time he is in the movie, it is easy to tell that he still loves his toys very much and they still feel the same about him. While Woody is having a nightmare after his arm accidentally ripped while playing with Buzz, Andy notices his rip saying that he does not want to play with Woody anymore and drops him into the cards left on the floor by Rex and Mr. Potato Head which lead Woody to land into a trash can filled with severed hands, Woody sees this yelling Andy not to do it and the severed hands grabs him by the neck sinking him and Andy sadly says goodbye to Woody and closes the trash can ignoring Woody's pleads. At the end of the film, Andy returns home from Cowboy Camp and is pleased to have five new toys, Jessie, Bullseye, and three Squeeze Toy Aliens, added into his collection and fix Woody's arm which has been fixed by the cleaner earlier and has been ripped open by Stinky Pete. Whenever Andy labels two of his new toys with his name on the soles of their feet. For Bullseye's case, Andy prints each individual letter of his name on each of Bullseye's hooves.
In Toy Story 3, seven years after the events in Toy Story 2, Andy is now 17 years old and preparing for college, intending to put most of his toys in the attic (except for Woody, whom he initially plans to take with him). While he apparently hasn't played with them some years ago, he still cares about them and is visibly upset when he can't find them anywhere. At the end of the film, Woody persuades him from afar to give them to Bonnie, the daughter of a family friend, who he realizes will look after them. When she finds Woody in the box as well, Andy shows great reluctance to pass on his favorite toy (who had the same issue with him throughout the film), but ultimately relents, allowing them to stay together in an environment where they'll be loved and played with. He spends a while playing with Bonnie and the toys one last time before leaving for college. From afar, his former toys see him off as Woody gives a final farewell.
Although Andy doesn't appear in Toy Story of Terror!, he is mentioned by Ron when he notices Andy's name on Woody's boot, thinking that it's his name.
Andy was mentioned by Rex in Toy Story That Time Forgot while trying to make Trixie feel better about never being played with as a dinosaur. Also, Bonnie and Mason mark their favorite toys, Trixie and Reptillus Maximus, respectively; just like he did with his four favorites.
Andy is constantly mentioned in the Toy Box world of this game, with Buzz becoming a target of Organization XIII due to the strong bond Buzz shares with Andy, and Sora relating to such bond to the bond he himself towards his own friends.
In Toy Story 4, Andy makes a brief appearance at the beginning of the film during a flashback segment two years after Toy Story 2 and five years before Toy Story 3. During a rainy night, Andy is first seen heading inside putting his toys on his bed before heading downstairs for dinner, and later, as Bo Peep was being given away, Woody considered going with her until Andy ran outside looking for him, making Woody realize just how much Andy needed him. He eventually finds him on the driveway. He is then seen in a few more flashbacks of him playing with his toys, and in another flashback of him giving his toys to Bonnie. He is also mentioned several times by Woody.
- The address of the Davis' second (and current) home is 234 Elm Street.
- Andy has been voiced by John Morris in every single Toy Story movie. Toy Story 3 was Morris' first role in more than a decade.
- Based on the T-Shirt he wears in Toy Story 2, Andy's "Cowboy Camp" takes place at Triple R Ranch, the setting for the classic Disney television serial Spin and Marty.
- The end credits of the first Toy Story movie has Andy's mom credited as Mrs. Davis, confirming Andy's last name is Davis. The beginning chapter of the book that contains Rex's POV of Toy Story 2 and the Pixar Pedia also shows this. However, it (as well as Andy's full name Andrew) is not displayed onscreen until Toy Story 3, where it is written on his high school graduation diploma.
- The original plans for a "Woody's Nightmare" scene in Toy Story have Andy throwing Woody in a trash can that gets trucked out to an alley when he notices that Buzz glows in the dark while Woody doesn't. However, this was ultimately unused, although only storyboards exist, finally found a place in Toy Story 2 when Andy trashes Woody because of his ripped arm.
- Andy's cell phone number is 555-0112, a number that is also seen in Monsters University when Mike shows Sulley a newspaper with the mailroom ad on it.
- At the end of Toy Story 3, he calls Jessie and Bullseye by their actual names. It is unknown how he learned their names, although he may have learned them from one of Jessie's pull-string phrases (which the real-life Jessie doll does say), or by either watching their show or investigating about them on the Internet or from friends.
- The shot of Andy giving Woody a ride on his back at the end of Toy Story 3 recalls one of the home videos his mom has made at the beginning of the film when young Andy has done the same.
- In the third film, when Andy is at his toy chest, deciding whether he should keep Woody or Buzz, it echoes the first film when he decides which to sleep with. In Toy Story, Andy chooses Buzz to sleep within his bed. In Toy Story 3, he chooses Woody to take with him to college.
- Woody and Buzz mentioned Andy when they were at the 2016 Oscars.
- If Andy was six in Toy Story, and if the film was set in the year it was released (1995), then Andy's birthday would have to be in 1989. This would also mean that Toy Story 3's release (2010) would not be the year of which the film would be set in, it would have to be 2006. This would also mean that his sister, Molly, would be born in 1994 and that she would be 12 in 2006. However, since none of the films or sources state any specific year where the films take place in, it is up to interpretation.
- The original storyboards indicate that Andy was originally going to wear eyeglasses.
