[1] Unlike other new Tekken 6 characters who were based on fan input, both Lars and fellow newcomer Alisa Bosconovitch were created using a different approach, focusing on their importance to the game's story.

[3] In response to claims that the story of Tekken was complicated, Harada denied as he saw it as a "simple" struggle between members from the Mishima family and how multiple characters are dragged into this.

His original outfit symbolizes multiple heroes in fiction with his armor being derived from Dragon Ball's Goku and Marvel Comics's Thor's designs.

Michael Murray explained the Tekken team created Lars in order to appeal to the Nordic audiences based on the series popularity in that region.

[6] In redesigning Lars, Kishimoto removed his Tekken Force outfit and gave him one made of a soft rubber material, marked with a lion figure on his right arm.

After multiple drafts that gave Lars different colors and accessories, Nin-Nin made one which retains elements from the Tekken Force design, while adding a torn red cape.

The developers called him "quick and agile" based on his varied moves, which were intend to give players multiple strategic possibilities and prevent them from being cornered against a wall.

For Capcom's crossover game Street Fighter X Tekken, the official guide encouraged players to use Lars' strong kicks in order to cancel his enemies' special attacks and get close to the rival.

[28] Harada said he thought Lars remained the strongest character to use in fighting tournaments, though others claim Steve Fox and the Mishimas – Jin, Kazuya and Heihachi – were stronger.

[32][33] Famitsu commented on Lars' moves from Tekken 7, specifically referring to his great speed and his techniques, which provide him with good defensive and counterattacking options.

The group originally met Harada during a Twitter conversation when one of the band members asked him where he could buy a Tekken action figure in Tokyo.

[37] BatAAr's theme song for Lars was ultimately titled "Vrede" (Swedish for "Wrath"), and included in both a CD single as well as the original soundtrack of Tekken 7.

[45] Teaming with United Nation's agent Raven, Lars pursues a fleeing Jin into the desert, where he intends to awaken the ancient demon Azazel.

[46] As Jin lost to Lars, he explains his main reason to start a war against the world is to lure out Azazel and kill him, believing him to be the source of the cursed Devil Gene.

[52] Lars returns in Tekken 8, with his Yggdrasill army and Lee's Violet System, in addition to a recently recovered Jin are one of the few remaining humanity's resistances left against Kazuya's tyranny.

While having Yggdrasil's alliance reconciled United Nations once again, they also gains expanded allies from Sirius, Kliesen Family and other presented fighters within the eight tournament who not only opposes Kazuya, but also Azazel and the loyal remnants of its original servants.

After gaining more aids from other fighters against G Corporation, ahead of the great war at Yakushima, Lars and United Nations admiral Victor Chevalier co-commands their allied force.

[57] In retrospect, Satō was shocked when learning Lars was Heihahchi's son, comparing it to Masami Kurumada's manga Saint Seiya which uses a similar plot twist involving a man like Heihachi, Mitsumasa Kido, having several offsprings secretly.

[63] He also appears as a playable downloadable content character in the crossover game Street Fighter X Tekken, with his official tag partner, Alisa.

In 2009, Matsuyama read in a Weekly Shōnen Jump magazine that Lars' third costume had been designed by Kishimoto and thought he should be included in Ultimate Ninja Storm 2.

As a result, Matsuyama approached Tekken 6 producer Suguru Sasaki and his team and asked them to include Lars in the game using Kishimoto's outfit.

[70][71] Different types of merchandise with Lars' image have also been released,[72][73][74] most notably a Tanahashi shirt which the wrestler wears during promotion of Tekken 7 in late 2017.

[78] Additionally, Lars appears in a Tekken 7 trailer recruiting guest character Noctis Lucis Caelum from Final Fantasy XV for an unknown mission.

[85] He was found his role in his first game was positive and compared him favorably to Mortal Kombat's newer protagonists at the time, like Shujinko or Taven, who he felt were less appealing.

[89] Because of Lars' moves, writers have often recommended that beginner players of Tekken 7 play as him with Vandal comparing him with Jin as well as Ryu from the Street Fighter series, due to how easy to use he is.

Kotaku's Mike Fahey liked it, as it helped to expand the game's roster, but thought other characters from the Tekken series would be more suitable than Lars.

[98] In the book The Language of Gaming, writer Astrid Ensslin commented that Lars had been criticized mostly by Western audiences because of the way his role in the Scenario Campaign mode is presented.

[104] Michael Higham of GameSpot enjoyed the new techniques Lars performed, positively comparing his to Sasuke Uchiha's lightning based Chidori move from the Naruto series especially in cinematics.

[106] Tu Trumann of GameRant also drew comparisons to Sasuke's Chidori and Kakashi Hatake's variant Lightning Blade due to how the flashiness of their techniques help to deliver a sense of power when executing it.

[108] The same site and Comic Book Resourcs enjoyed his fight against Kazuya in the scenario mode as Lars evokes the strength of Heihachi when facing his half-brother.
