The concept for Galidor as a toy line with an associated television series was created by the Lego Group, hoping to break into a new merchandise market during a period of financial trouble.

In the Outer Dimension, Nick displays a shapeshifting ability called glinching, allowing him to transform his limbs into different mechanical or organic objects.

They are Jens, a plant-like being preserved in a robotic form; Euripides, the last survivor of a genocide enacted by Gorm's forces; and Nepol, a warrior of the Siktari people.

Gorm now wants to conquer the Outer Dimension including Galidor, seeking out Nick's glinch powers to ensure his victory.

Nick was left on Earth to hide him from Gorm, who managed to steal a piece of his glinch abilities, before Galidor was sealed away by Riana.

The main storyline revolves around Nick and his allies finding fragments of the key to unlock the gates of Galidor, racing against Gorm and his agents while helping the people of the Outer Dimension's realms.

The series ends with Nick reaching Galidor and reuniting with Riana, while Gorm is revealed to have survived and is holding Sam hostage.

During the late 1990s to early 2000s, Danish toy company The Lego Group were suffering from falling profits; while licenses for franchises such as Star Wars and the in-house Bionicle line proved profitable, at the time there was a market shift away from the style of brick building toys the Lego Group had designed up to that point.

[9] Drawing inspiration from the Hero's journey concept,[1] Nicholas was created as a character dealing with feelings of both personal and social isolation.

This worried him, as he assumed the purchase was due to the commercially-successful Power Rangers franchise, and that Disney would not be interested in funding new series like Galidor.

[1] Galidor began simultaneous broadcast on YTV in Canada and Fox Kids in the United States on February 9, 2002 in the morning time slot.

[34] In their 2002 fiscal report, the Lego Group felt that the series had failed to attract the predicted popularity needed in the United States.

[1] In a review for the Rome News-Tribune after its first few episodes aired, Evan Levine cited the special effects as Galidor's main attraction, otherwise finding the premise and characters unoriginal.

[1] In a Bloomberg News article about the Lego Group in 2010, Jay Green referred to Galidor as "a Saturday morning cartoon cliché" which was dismissed as a long commercial for the toy line.

[38] In 2013 David Robertson, then a practice professor at the University of Pennsylvania and co-author of a non-fiction book on the Lego Group, called the television series bad and felt it had negatively impacted the careers of its actors.

[39] As part of a 2021 article on the Power Rangers franchise, Paste Magazine's Dave Trumbor mentioned the show as one of several productions at the time that failed to gain an audience, stating they had "abysmally immature computer-generated graphics as stand-ins for suited monsters".

An adventure game played from a top-down perspective, the goal was for the player to create an Outer Dimension character and progress the story through combat and solving puzzles.

[1] In December 2001, the Lego Group partnered with Electronic Arts to publish a video game tie-in based on the Galidor toys and series.

[46] During this period, Asylum Entertainment staff saw the mixed reactions series and toy line, and were eager to get it finished and move onto a new contract.

[1][53][54] Production of the toy line ran parallel with the series, led by senior Lego Group designer Niels Milan Pedersen.

The design drew inspiration from a number of early concepts about evolving and merging creatures, with the specifics coming together following talks with Lynch.

[56] One notable element of the crossover was the Kek Powerizer, a hybrid design combining the action figure elements with a rudimentary electronic device which would play sound clips based on both the parts attached to the Kek Powerizer body and the sound signals received from either the television series or video games.

[1][38][41] The Galidor toy line was discontinued in 2002 leading to some sets being cancelled,[1][62] with the Lego Group's stating they would abandon the action figure style going forward.
