Buzz Lightyear - a "space ranger", and wears a space suit with various features such as retractable wings and transparent helmet, a laser "weapon", and various sound effects. In Toy Story, he begins the series and develops a rivalry with Woody, who resents him for getting more attention as the newcomer. He is extremely loyal to his friends. During his time trapped at Sid's house, Hannah, Sid's sister, called Buzz Mrs. Nesbit. In Toy Story 2, Buzz goes to save Woody from Al with Potato Head, Ham, Rex, and Slink (Slinky Dog) where he gets stuck in the Buzz Lightyear aisle in Al's Toy Barn by another Buzz and finds out for himself what he was really like. In Toy Story 3, a friendship begins to develop between Buzz and Jessie. He is particularly open with his affection when switched to "Spanish mode".Jessica Jane "Jessie" Pride -a cowgirl, and part of the Woody's Round Up gang. She first appeared in Toy Story 2 along with Bullseye and Stinky Pete. Initially, Jessie was hesitant to join Andy's friends. After she becomes part of the family, she is very happy (after the despite the Andy first calls her Bazooka Jane). In Toy Story 3, she was riding Bullseye when Woody fell off the train in Andy's opening sequence. She argued with Woody on their way to Sunnyside Daycare because of when the others think Andy threw them out. Later in the film, Jessie feels close with Buzz, even when Buzz got switched into Spanish. At the end, Jessie and Buzz danced to the Spanish version of "You've Got a Friend in Me". Jessie also appears in Pixar's Monsters inc. as one of the toys Boo gives Sully.Stinky Pete, or also known The Prospector-is a prospector doll. He is a toy modeled after a character on the fictional television show, Woody's Roundup, where the characters consists of Sheriff Woody, Jessie, Stinky Pete, and Bullseye. The Prospector doll seen in the film had never been opened and was still "Mint in the Box", making him sought after by collectors.Mr. Potato Head (often referred to as simply Potato Head)- a doll based on the real-life toy by Playskool. He is an outspoken and sarcastic potato-shaped toy: his patented design allows him to separate his detachable parts from his body by removing them from the holes on his body. He also has a compartment on his lower back to store extra appendages. He is capable of retaining control over his parts even if they are several meters away from his main body. For example, he can still see if one or both of his detachable eyes are removed, as well as being able to move his hands if they are detached. The same thing applies to his "Mrs." counterpart, as she was able to see Andy in his room through her eye left behind. While this attribute is mostly used for comedic effect (i.e. as a running gag, he often finds himself being split or falling apart due to outside forces), it does have its uses, particularly in the second and third films.Rex- an excitable large, green, plastic Tyrannosaurus rex who suffers from anxiety, an inferiority complex ("I just don't think I could take that kind of rejection!") and the concern that he is not scary enough. Rex's worst fear (after Sid) is that Andy will get another, scarier dinosaur, but feels better after Buzz gives him a few pointers on how to roar more effectively. He is among the largest of Andy's toys, and is often depicted as the heaviest. He is voiced by Earl Boen in the Toy Story 2 video game. Comic irony is created by the fact that although Rex is a toy dinosaur he dislikes confrontation and is sensitive in nature.In Toy Story 2, the toys discover Barbie dolls in an aisle while searching for Woody. Hamm asks them if they know where Al is. Tour Guide Barbie volunteered to help and got in their car and gave them a tour around Al's Toy Barn. The toys crash into a bouncy ball machine when Rex showed his strategy guide in front of everyone, making Tour Guide Barbie not see where she was going. Rex chased after the car when he fell off, making Tour Guide Barbie tell everyone to remain seated, along with reciting it in Spanish. During the end credits she is a cinema usherette and is seen giving out instructions to the audience. After a while she asks if everyone has gone and promtly stops smiling and complains that it hurts her face. She then leaves for her breakWheezy (also known as Wheezy the Penguin) - a rubber squeeze toy penguin with a red bow tie.In Toy Story 2, Wheezy is introduced when Woody finds him on the shelf, where Andy's mom had put him intending to fix his broken squeaker, then forgot about him. He is about to be sold at the yard sale, and in saving him, Woody ends up falling so that he is stuck at the yard sale himself and subsequently stolen by Al. At the end of the film, he gets a new "squeaker" and sings "You've Got a Friend in Me", the ending theme of the movie. During the outtakes, he describes himself as "not a good catcher" as he fails to catch Mike's microphone thus hurting himself several times.Wheezy does not directly appear in Toy Story 3 as he was sold in a yard sale 5 years after Toy Story 2, as mentioned by Woody, but he does appear in footage of Andy as a boy. Wheezy appears in the Toy Story 3 video game, where he is voiced by Charlie Adler in toy box mode along with Bo Peep.Slinky Dog is among one of Woody's most faithful, loyal companions; a plastic dachshund with a Slinky replacing a midsection. He shares a particularly close bond with Woody, as mentioned earlier, and is depicted as being typically easygoing, relaxed, and friendly. As an occasional gag, his abdomen may either benefit or burden him with its uses and disadvantages, such as its capability to stretch to convenient lengths or it becoming intertwined with various objects. He first debuted in the first film of the franchise, in which he appeared to be among the most faithful to Woody even after his betrayal of Buzz (albeit he still seemed skeptical of Woody after his return, but seemed reluctant to accept the facts of the cowboy's vengeance). He may usually play a slightly minor role, but peppered with moments of vitality in the film, such as endeavors embarked upon by the toys, where the advantages presented by his convenient Slinky midsection can be used as a weapon or helpful tool. He reappeared in Toy Story 2 in a slightly larger role, accompanying the other toys on their quest to locate Woody who has been snatched by a toy collector named Al at a yard sale, but still filling a similar purpose as on other occasions. Naturally, he made an appearance in Toy Story 3 as well, where, like the others, he was crestfallen by Andy's maturity and donation of the toys to a daycare center in which they are subjected to violent play and abuse, joining the others on missions and on accomplishing goals, and was later adopted by Bonnie. In this film, his Slinky body was very useful in one scene, when he helped to bridge a gap between a ledge and a bin when they try to escape the daycare.Hamm is a wise cracking realist piggy bank with a cork in his belly in place of a stopper. He and Mr. Potato Head appear to be best friends, and are often seen playing games, such as Battleship (with Hamm always winning). Out of all the toys, he is shown to have the most knowledge of the outside, often being very familiar with various gadgets that are shown, likely as an homage to Ratzenberger's famous role of mail carrier and bar know-it-all Cliff Clavin on the sitcom Cheers. 以上是全部的简介,如果嫌长的话可以删去一些.
