''Gad Guard'' is a TV {{Anime}} from studio {{Gonzo}} directed by Hiroshi Nishikiori. With an original run between April and September 2003, the series culminates in 26 episodes. A LightNovel was adapted from the {{anime}} with illustrations by Izuna Yoshitsune and published by Media Factory in 4 volumes.

The story takes place several hundred years in the future, the resources of the Earth having run out, the progression of the human race stagnated and the world divided into "Units". Hajiki Sanada lives with his mother and sister in Unit Blue, in a place called "Night Town", where all electricity is shut down at midnight. Haijiki often skips school to work as a courier earning money for his struggling family. One day he has a chance encounter with a [=GAD=], a device with the ability to reconstruct materials while reacting to feelings of an organic life, which transforms into a giant robot. Together Hajiki and his new Techode set off on a journey of personal discovery to locate the other [=GAD=]s and their owners, who may be friend or foe alike.

!!This anime provides examples of:

* AfterTheEnd: A relatively tame example. Civilization's in a major slump, but hasn't descended into complete insolvency.
* BadAss: Hajiki Sanada, eventually.
** Katana, definitely.
* CrapsackWorld: Things aren't too bad living in good parts of the city like Gold Town, but poorer areas and those outside the cities just get grimmer and grimmer.
* DisappearedDad: Hajiki's dad was an astronaut test pilot who died when Hajiki was young.
* EeriePaleSkinnedBrunette: Katana pulls this off with blue hair.
* EmpathicWeapon: The Techodes are able to move and react according to their masters' emotions and personal wishes, as well as their innermost characters. [[spoiler: This explains why it seems that Thunderbolt goes berserk on Messerschmidt; although Takumi has nothing against Aiko, it seems he harbors a somewhat wrathful spirit along with his rather black-and-white desire for justice]]
** [[spoiler: The scarred man seems to have an attachment to Lightning, as his movements are also it's own. It is revealed that the nature of the Techode was split, and when they become one again, Lightning seems to get the ability to talk and sentience, as it seems.]]
* EnemyMine: Katana pulls this during the fight with the train A-Techode.
* GaiasLament
* GiantRobotHandsSaveLives: Many ''many'' times.
* HumongousMecha: Notably, of the retro Anime/{{Gigantor}} mold, as opposed the much more popular piloted type.
* KnightTemplar: Takumi. He mellows out towards the end though.
* MacGuffin: The [=GAD=]s.
* MagicSkirt: Arashi, considering it's tiny and she fights with kicks. Also Aiko has a habit of running around in one that looks more like a belt.
* MoralityPet: Sayuri, to Katana. [[spoiler:She existed only because he needed her after all.]]
* MrFanservice: Katana, the [[TheStoic cool]], [[IneffectualLoner brooding]], [[TallDarkAndHandsome handsome]] guy in the BadassLongcoat who also [[TheGunslinger kicks ass]], has a HiddenHeartOfGold and is voiced by Creator/JunichiSuwabe.
* NamesToKnowInAnime:
** Creator/KenichiSuzumura and Creator/TonyOliver: Hajiki
** Creator/JunichiSuwabe and Creator/DaveWittenberg: Katana
** Creator/FumikoOrikasa and Creator/KariWahlgren: Arashi

** Creator/MasayoKurata and Creator/MichelleRuff: Aiko
* NotDistractedByTheSexy: Katana couldn't care less about Wanda's attempts to seduce him.
* NotSoDifferent: Hajiki and Katana, mainly about how they both use their Techoid for violence. Hajiki is not very happy when being reminded by people around him (Katana included) about that.
* OddlyVisibleEyebrows
* OfficialCouple: [[spoiler:Hajiki and Arashi. Takumi and Aiko may be the BetaCouple.]]
* OlderThanTheyLook: Takumi is short and looks about 10, but he's in his mid-teens.
* {{Ojou}}: Aiko, though she doesn't have the haughty personality.
* [[spoiler:ReunionKiss: Arashi and Hajiki shared one of these in the last episode.]]
* TheRival: Katana. [[spoiler:He later graduates to being an AloofAlly.]]
* TokenMiniMoe: Sayuri of course. She's the youngest character in the show, positively tiny and made of cute.
* {{Tsundere}}: Arashi to Hajiki in the beginning, [[spoiler:before she comes to terms with her feelings]].
* ScarfOfAssKicking: Hajiki's Technode has two exaust pipes that look (and move) like one.
* ThemeNaming: The main characters' Techodes are all named after WorldWarII fighter planes.
** Hajiki and Katana are named after weapons, the gun and the sword respectively.
* TheOnlyOneAllowedToDefeatYou: Katana towards Hajiki, after Hajiki destroyed the Techode Katana built himself.
