Yu-Gi-Oh! D.N.Action!

'''Yu-Gi-Oh! D.N.Action!''' is a spin-off of the Yu-Gi-Oh! anime series. It takes place before Yu-Gi-Oh! HEARTZ. It would've been one of the most popular shounen anime besides the traditional Yu-Gi-Oh! series.

Summary Sypnosis
The series is set in a parallel universe, and takes place in Sigma City, a fictional Japanese city and a bustling metropolis. The city's layout is similar to that of New York City, with the main city being divided into five Districts, four being mainland (Alpha, Beta, Gamma and Delta) and one being an island (Zeta). High-speed monorails allow easy access between the Districts.

Syrus Truesdale becomes a star of the Cyber Art Pro League, along with his brother, Zane Truesdale. Until one day, during a visit to the KaibaCorp, Syrus gets himself into a shocking accident that fuses his DNA with the DNAs of the eight legendary duelists of different eras and dimensions: Yugi Muto, Jaden Yuki, Yusei Fudo, Yuma Tsukumo, Yuya Sakaki, Yusaku Fujiki, and Yuga Ohdo, which gives him the strength, speed, agility, spirit, and the dueling skills and strategies of these dueling heroes!

Now, with his life turned upside down, not only does Syrus leave behind his Cyber Art Pro League career and become Jaden's and the other duelists' new and genetic brother, but it'll be his turn to become a new dueling hero that goes by the name he gives himself for his new form, Yusuke Soarin, and save the world from new threats with his new skills, a new deck along with a new duel disk, and also learning how use a new summoning ability called DNA Summon!

However, Syrus won't be doing it along as there will be some new friends and new monsters to add to his deck along his way, while he still has a lot to learn how to use his new abilities and how to use the new summoning skill if he'll have to prevent Master Obsidus from affecting all humans and duel monsters with Dark DNA.

Main
Yusuke Soarin (Syrus Truesdale)/Yusuke Marufuraito (Sho Marufuji)

The main character who used to work for the Cyber Art Pro League with his older brother, Zane Truesdale, until during a visit to KaibaCorp with their old friends, a shockwave accident occurs in Syrus that causes his DNA to be infused with the DNAs of the eight duel heroes. Since he has all seven of the DNAs combined with his DNA, including Jaden's DNA, Syrus becomes the genetic brother of them and learns that will have to use his new abilities, intelligence, and skills of those duelists to protect his friends and the world from evil, like the Master of Dark DNA, Master Obsidus, by using a new watch-like device called a Duel Watch that transforms into a duel disk when he transforms into his alias form, Yusuke Soarin (Yusuke Marufuraito in Japanese dub), and use a new duel summoning ability called DNA Summon.

His ace monster is the DNA duel monster Jumpstart Dragon and his spirit partner is Junkuriboh.

When he and Syrus were kids, he gave a copy of his Power Bond card to him but told him to not use it for play which made Syrus develop a lack of confidence until their year at Duel Academy, Syrus had managed to prove Zane wrong by becoming a stronger duelist thanks to Jaden Yuki, who was soon the genetic brother of Syrus in the future after Syrus had his DNA fused with his, along with the other DNAs of the seven legendary duelists.

Although his younger brother's DNA is infused with the legendary duelists' DNAs, including Jaden's DNA, he still remains as a Truesdale.

Jaden/Judai Yuki

A handsome, hot-blooded and famous Slifer Red duelist who graduated from Duel Academy like Syrus and their friends, and is now a world traveling duelist who is thriving to be the next King of Games like Yugi Muto.

His ace monster is the Elemental HERO Neos and his spirit partners are Winged Kuriboh and Yubel, who is fused with Jaden after their duel in another dimension.

Known for his singing voice and guitar skills, he is referred to as the "Slifer Rocker", mainly because he is a Slifer Red duelist while he is an aspiring rocking musician, as he got a red electric guitar from his travels.

Bryan Everglade/Kaede Miura

A small and very intimidated duelist who was picked on by a group of bullies, who made fun of him and his deck, until Yusuke stood up for him by dueling the leader of the gang. He has a great sense of honesty and holds a deck full of plant-type monsters and Fluffal archtype monsters.

Jarred Stone/Akira Kato

Yusuke's rival who holds gem monsters in his deck and envies the main protagonist because of his DNA duel monsters that he thrives to be better than him by dueling him, only to lose. However, he begins to warm up to Yusuke (despite not knowing his true identity) and becomes an ally to him, although he still keeps his snarky personality.

Manga
This is the first time the manga isn't being serialized in Shueisha's V-Jump, but rather Weekly Shonen Jump, unlike other spin-offs. Also, the manga was released before the anime and follows the same story as the latter.

Anime
The anime is aired worldwide on Jetix Network, through the block titled Anime Invasion.

Unlike the 4Kids/4K Media dubs, the Western version of this anime has no plot edits nor censorship, making it more loyal to the original Japanese version, and actually includes fanservice, mostly involving Jaden's handsomeness. Thankfully, 4K had now lost the rights to the Yu-Gi-Oh! series, which even lead to Jetix owning the rights, and starts undoing the mess that 4K had done.

Video games
Several games inspired on DN-Action have been developed by Spike Chunsoft and published by Konami worldwide (e.g. World of DN-Action! and Duelverse).

Music
Opening Music: DNA Charge! (international) / Light Colors by Lia, covered by KENN (Japan)

Ending Music: DNA Charge! Instrumental (international) / Get Up & Move!! by Koda Kumi, covered by KENN (Japan)

Image songs
A series of character songs/singles from the anime and video games were released by Jetix Records, a subsidiary of Disney Music Group, via Creative Commons. It spawned a set of singles featuring the main cast, such as Yusuke/Syrus (Masami Suzuki), Jaden (KENN) and Mana (Yuki Nakao).
