A large portion of the Machine Robo toy line was exported and sold by Tonka in America as GoBots and Rock Lords. Central Park Media released 15 English-subtitled episodes of the series on three DVDs in 2003; these remained the only official English releases until 2022, when Discotek Media released the complete series and its associated OVAs on one SD Blu-ray set.


The story takes place on the mechanical world of Cronos. A band of villains called the Gyandlar have come to the planet in search of the mythical energy known as the Hyribead.

Kenryū (Blade Dragon)
Larger robot body of Rom Stol. At the peak of light energy, Kenrō can cross the dimensional barrier and call forth Kenryū. When Rom combines with Kenryū, his power increases by tens. When the combination is complete, he says, "Wherever there is darkness, there is light. Wherever there is evil there is also good! The emissary from the heavens, Kenryū, is here!"
Baikanfu (ViKung-fu)

Original video animationsEdit

Leina Stol in Wolf Sword LegendEdit

When Revenge of Cronos left off, Rom and Leina had crossed a dimensional barrier. Their physical forms changed from robot to human, and they were separated, with blurred memories. Leina Stol is incarnated as Reina Haruka, a Japanese schoolgirl. As the story progresses, she meets up with Rod Drill, Blue Jet, Triple Jim, and Rom, all of whom are now human. Given the fact the Revenge of Cronos robotic characters appear here in new human forms, the Blue Jet and the Rod Drill appearing with the usual robotic forms in Battle Hackers may be all-different robots.

Lightning Trap - Leina & LaikaEdit

Taking place in the middle of the Wolf Sword Legend feature, this story centers on Leina Haruka, whose plane has been hijacked by a group of thugs led by the supernatural wizard Zarik. At this point, the series has no resemblance whatsoever to the Machine Robo toy line that spawned it.

Video gamesEdit

Machine Robo was featured in three of Banpresto's Super Robot Wars series, beginning with SRW Compact 2: Part 2 & 3 in 2000 on the Wonderswan. All three parts of SRW Compact 2 were remade in 2002 as SRW Impact on the PlayStation 2. In 2004, the series was included in the PS2's SRW MX's line-up, as well as the PSP port of the same.
