Tecktonik (TCK), also known as Electro Dance , was a French youth subculture and dance phenomenon that surged in popularity between 2006 and 2008. The movement originated in the early 2000s at the Metropolis nightclub outside Paris, where events organized by Alexandre Barousdin and Cyril Blanc promoted electronic music genres like hardstyle and jumpstyle.

The culture rapidly spread from the Parisian club scene to a mainstream audience, primarily through online video platforms like YouTube, becoming a short-lived but intense international fad. The aesthetic is defined by its energetic and intricate dance style, which combines elements of rave , hip-hop , and voguing, and a distinctive fashion featuring tight-fitting clothing, punk -inspired hairstyles like mullets and mohawks, and bright, often neon, colors. The trend's decline was as swift as its rise, largely attributed to over-commercialization and its perception as a fleeting fad.

Tecktonik emerged in Paris during the early 2000s, within a broader European context of popular electronic music and the popularity of rave culture. In 2002, Alexandre Barousdin and Cyril Blanc coined the term "Tecktonik," derived from the French "tectonique" (tectonic), and began organizing "Tecktonik Killer" events at the Métropolis nightclub in Rungis. These events, part of "Tecktonik Events," aimed to promote Dutch and Belgian musical genres like Jumpstyle and Hardstyle within France. The scene featured dance battles incorporating styles such as Melbourne Shuffle and breakdancing, alongside visual elements like colorful LED lights, fire effects, and boxing rings. Participants in the early scene were referred to as "Killers" (masculine) or "Killeuses" (feminine).

In 2006 and 2007, the Tecktonik subculture quickly became a major trend thanks to the internet and forums such as Skyrock. One of the most popular videos  ever was "Wantek Danse electro!!!" by Jey-Jey, which gained 1 million views at the time. Consequently, it became a significant cultural export among teenagers in countries such as Côte d'Ivoire, Madagascar, Russia, Mexico, Japan and Spain. In the rest of France, many children and teenagers followed the trend and danced to Tecktonik at school or lycée (French secondary school). In June 2007, Tecktonik dancers were present at LGBT+ Pride month parades in Nantes and Lyon.

The unexpected incredible success of Tecktonik gave the creators the idea to turn it into an official trademark to start profiting off the movement and its potential. They sold all types of mass-produced merchandise trademarked as "Tecktonik," including T-shirts, oldschool phones, bags, fingerless  gloves, bracelets, purses, chewing gum, energetic drinks, branded hair shampoo and gel, belts with LED lights, and even an official video game for the Nintendo DS console, titled Tecktonik: World Tour . They even opened two official hair boutiques where people could get hairstyles with Punk crests, fluorescent hair extensions and dark make-up with star shapes. These hair salons made approximately 20,000 euros per month. Although Alexandre and Cyril Blanc made a lot of money off all of the merchandise, it was also problematic for the members of the subculture since they couldn't use the registered trademark for their own music events. That's why Tecktonik slowly started to fall apart: it was a musical movement that brought together people from all over the world but later became a simple, commercialized and profitable image because of businesses.

In 2008 it started rapidly declining. The Métropolis nightclub stopped hosting the Tecktonik music evenings, and iconic bands that shaped the subculture such as Yelle switched to other dance genres. Many people who participated in Tecktonik were mocked or cyberbullied online, and Hip-Hop and Rap became the next big trends in Paris during that year. Rappers and Tecktonik Killers had friendly rivalries as street fashion as well, and one notable example is the song " Anti-Tecktonik " by Sexion D'assaut. In the music video, this French Hip-Hop band pretends that they are hunting the members of the Tecktonik subculture and jokes about hurting or killing them with baseball bats.

Tecktonik fashion includes:

As a trademark, the official logo or trademark of the Tecktonik subculture is a grey heraldic eagle, split in half by a saltire that reads "Tecktonik" along with a pink star. This logo tends to be used in T-shirts and related merchandise, and the colors used may vary. 
When Tecktonik became a major trend in France and around the world, Alexandre Barousdin appropiated the very movement he started to profit off it. The logo was used in all types of merchandise, from T-shirts to drinks and even shampoo brands.

Contrary to popular assumption, Tecktonik (also known as Milky Way or Electro Dance ) is not actually a musical genre. Instead, it's a distinct dance style that emerged from dance battles in the Métropolis nightclub. The choreographies tend to be individual and vertical (the dancer never lies down or does somersaults) and the dancers usually keep their feet on the ground, even when elements related to kicks in the air are included. The most distinctive aspect of the dance style are the arm movements, with quick turns of the elbows in all directions.

The music associated with Tecktonik is primarily a fusion of Electro House, [Hardstyle, and Jumpstyle variants, characterized by a high BPM and metallic synth leads.
