Tiny Tina

 is an NPC in Borderlands 2. She is a an unstable thirteen-year-old explosives expert, and was revealed on February 21, 2012, in the Borderlands 2 Launch Date Trailer.

Involvement
Tiny Tina's demolitions expertise are called into action when a Hyperion supply train believed to be carrying a vault key needs to be stopped. With that objective in sight, she then sets the Vault Hunters to the task of finding two rockets to carry a 'suicide'-bomber toy each, and then to set them on target.

Her collaboration with the Vault Hunters continues when she has them gather items and guests for a very special tea party.

Mr. Torgue's Campaign of Carnage
Tina appears in a supporting role in Mr. Torgue's Campaign of Carnage. Initially she is hired by Moxxi to help the Vault Hunters train prior to battling Motor Momma, but also asks their assistance in obtaining the autograph of her third favorite mass-murderer, Sully the Stabber, as well as walking her "puppy", a Badass Fire Skag named Enrique. She also provides commentary on many of the Vault Hunters' actions throughout the course of the DLC.

Trivia

 * Her voice is done by Ashly Burch, sister of Anthony Burch - Lead writer of Borderlands 2. (The two are also a part of the web series Hey Ash, Whatcha Playin'?.) She is also credited with the voice of the cursed gun, Bane.
 * Roland recognizes her as one of the greatest demolitions experts on Pandora and a picture of the two can be seen inside of her home.
 * Tiny Tina is mentioned by Brick on a mission in Sawtooth Cauldron as he recalls carrying her on his shoulders as they fought together. In the end credits, it is shown that they worked together again in this manner cleaning out the remaining Hyperion forces.
 * She sometimes starts singing the "Baby Finn Song" song from "Adventure Time".
 * Tina seems use several verbal mannerisms, often at random. They include a stereotypical Black American speech pattern, little girl speech patterns, stereotypically pretentious British English speech, to randomly violent and murderous speech similar to Psychos, and others.
 * Tina has amblyopia in her left eye. This was originally due to a glitch, but the developers enjoyed it, so they purposefully left it in.
 * In NowGamer, an interview revealed that there is part of a quest removed from the main game involving Tina. Originally, when telling of Roland's death, the players were to head out to Tiny Tina's home and tell her the sad news. It described her being deeply affected by it, and locking herself in her workshop to mourn. Anthony Burch, lead writer and the source of this news, says they regret they could not include this scene into the game. It was supposed to be the only moment in the game she loses her peppy mania.
