Claptrap

Claptrap is a character from the Borderlands games.

A type of Hyperion robot designed to provide assistance to settlers and newcomers to Pandora. They are almost universally hated by the population of the planet, and the bandits use them as target practice. The one who greets the Vault Hunters in Fyrestone is the most ubiquitous, and becomes a more major character in the second game, eventually becoming a playable character in the Pre-Sequel.

His action skill has him run VaultHunter.exe, a buggy program that analyses the battlefield and grants him a random ability it deems appropriate for the situation.

Personality
It has been programmed with an overenthusiastic personality, and brags frequently, yet also expresses severe loneliness and cowardice.

Abilities
Action Skill: VaultHunter.EXE. Base cooldown 40 seconds.

Claptrap's action skill analyzes the combat situation and chooses the most suitable "Action Package", providing it with bonuses and an appropriate fighting style for a short period. Some bonuses may also affect nearby teammates. Activating the skill instantly fills Claptrap's health, and it provides health regeneration for its duration.

In addition to Action skill, and unlike any other playable character, Claptrap can unlock and use Action Packages: Claptrap has three skill trees:
 * Torgue Fiesta
 * Pirate Ship Mode
 * Clap-in-the-Box
 * Gun Wizard
 * One-Shot Wonder
 * Laser Inferno
 * Boomtrap
 * I Love You Guys!
 * Fragmented Fragtrap

Trivia

 * "Claptrap" is an archaic word synonymous with drivel or babble, which is clearly not coincidental, since in-game claptraps ramble on and are rarely not speaking.*
 * Claptrap was born from a random sketch in a low-level assignment made by the JIRA project-management software system.
 * In the German version the initial Claptrap introduces himself as "CLP4P-TP", even though the subtitles read "CL4P-TP".
 * Claptrap is the only Claptrap that has been designated with an actual name, Claptrap P. Claptrappington.
 * Claptrap appears as an Easter Egg in Torchlight II. It offers a socketable item called Claptrap's Nut or Claptrap's Bolt.
 * Claptrap appears as one of the opponents in TellTale Games' Poker Night at the Inventory 2.
 * In bounty rounds, Claptrap bids with its Spike Video Game Awards Best New Character award. If the Borderlands inventory is unlocked, it wears a top hat and has a tuxedo decal. If the Portal inventory is unlocked, its design and paint job reflect the sleek white coloration and general design of Aperture Science's cores and turrets. It also has a (very one-sided) attraction to Portal's GLaDOS.
 * Claptrap mentions that all Claptraps are equipped with 8th Generation Emotive Resonators, allowing them to mimic a wide range of emotions.
 * Claptrap expresses excruciating pain when its eye is ripped out in Borderlands 2, but later when it is beaten by bandits it states that it cannot feel pain. The Claptrap unit featured at the start of Borderlands: The Pre-Sequel however, states that robots feel pain "in slow-motion with great intensity".
 * In Borderlands 2, Claptrap breaks the fourth wall in the mission Claptrap's Secret Stash when it addresses players directly and advises them that they can use the stash to twink their characters.
 * Claptrap's color scheme, yellow with a white stripe in the middle, matches that of a green quality Hyperion weapon, while the Jakobs claptrap has a color scheme that matches a purple-quality Jakob's weapon.
 * In Borderlands: The Pre Sequel, Claptrap shows jealousy when it meets a regular Claptrap, as the other Claptrap doesn't have to fight and just opens doors.
 * In Borderlands: The Pre-Sequel, Claptap's combat style is listed as "It's not stupid. It's advanced!". This is the exact same line given in the TV series Invader Zim when Zim is given Gir, his faulty robot.
 * He has a quick cameo in Ready Player One. The character Percival walks past a small booth with him in it after big race near the beginning of the film.
