Streaming service Viewster has added the Tenjho Tenge television anime and the Galaxy Express 999 and Adieu Galaxy Express 999 anime films. In addition, the streaming service has expanded its regional availability for the DNA² and Mazinger Edition Z: The Impact! anime to include the United States and Canada — both shows were previously available in other territories.

The 2004 Tenjho Tenge anime adapts Oh! great's school fighting manga about the violent brawls that ensue at Todo High, a school dedicated to training its students in the art of combat. Geneon Entertainment previously released the series on DVD in 2005-2006, and Discotek Media released the series in 2014. Toshifumi Kawase (Beyblade, Matchless Raijin-Oh) directed the series at Madhouse Studios and Toshiki Inoue (Death Note, Dennō Coil, Chaos;HEAd) handled the series composition.

Viz Media is releasing the original manga unedited in North America. DC Comics' CMX Manga line previously released the manga series with edits through volume 18 before the imprint was closed in 2010.

The 1979 Galaxy Express 999 anime film, like the television series of the same name, is based on Leiji Matsumoto's original manga. Discotek Media released the film on DVD in 2011 and describes the story:

Galaxy Express 999 is the name of a train which travels through space, beginning at Megalopolis Station on one end of the galaxy and ending at Andromeda on the other. But the Galaxy Express is more than just a train - it's also a metaphor for life itself, with passengers constantly boarding, debarking, and dreaming along the way. Tetsuro Hoshino is a youth who'll give anything to board the Three-Nine, including a promise to accompany a mysterious woman named Maetel all the way to Andromeda, the planet where, she tells him, he can get a free machine body to avenge the cruel death of his mother at the hands of the villainous Count Mecha. But nothing is as easy as it sounds, and Tetsuro is about to learn the true price not only for boarding the Three-Nine and avenging his mother, but for leaving his childhood behind, falling in love, and becoming a man.

Discotek released the Adieu Galaxy Express 999 anime film on DVD in 2011, and it describes the film:

Tetsuro Hoshino was once a boy willing to give anything to board the Three-Nine, including a promise to accompany a mysterious woman named Maetel to the other side of the Galaxy, if only to fulfill a vow to avenge the cruel death of his mother at the hands of the villainess Count Mecha. Now, two years after the events of Galaxy Express 999, Earth has become a battlefield, and Tetsuro is summoned to board the Three-Nine once more. All questions will be answered and all mysteries revealed as Tetsuro embarks on a journey the destination of which is unknown even to the Galaxy Express Railways locomotive C6248 itself... a journey which will reveal a secret so awful, even Maetel herself can hardly bear speak of it.

The film debuted in 1981 as a sequel to Galaxy Express 999 and Galaxy Express 999: Glass no Clair films.

The television anime of the DNA² manga by Masakazu Katsura (Video Girl Ai, I''s ) aired in 1994. There was also a three-episode DNA² original video anime project in 1995. Central Park Media released the entire series in 2003 on DVD and described the story:

Junta has a problem. He's deathly allergic to girls! All this changes when a beautiful woman arrives from the future and transforms him into the super-suave Mega-Playboy. But the transformation is unstable, and if Junta can't unravel the time traveler's mystery, he (and the fate of the world) will never be the same!

Discotek revealed in 2013 that it had licensed the series, and it shipped the DVD with all 15 English-dubbed and English-subtitled episodes in June 2014. Crunchyroll added the anime in May 2015.

The Mazinger Edition Z: The Impact! anime is based on Go Nagai's 1972 Mazinger Z manga and television anime, and it premiered in 2009. Discotek Media released the series on DVD under its Eastern Star label in June 2015, and it describes the series:

What would you do if you had ultimate power thrust into your hands? As a normal high school boy, Kouji Kabuto never thought he would have to face that problem. But when your grandfather is a scientist known for having discovered the means to end the world's energy crisis, just living a quiet life in a mansion isn't going to last. Japanium, an ore capable of producing Photon Energy, promises to lead humanity into a bright future... though not everyone wants to use it for good. The evil Dr. Hell is determined to use Photon Energy to power his malicious Mechanical Beasts, which would make him unstoppable! Darkness falls upon Kouji's home town of Atami, the first city lit by Photon Energy, and the first step on the doctor's quest for world domination! Not all is lost, however, as Kouji's grandfather grants him the power of Mazinger Z - the ultimate fighting robot!

Crunchyroll added the anime earlier this year in April.
