Machine Robo: Revenge of Cronos (マシンロボ クロノスの大逆襲 Machine Robo: Chronos no Dai Gyakushū?), known in English as Revenge of the Gobots, is a Japanese anime television series produced by Ashi Productions. It ran on TV Tokyo from July 3, 1986, through May 28, 1987.[1]

A large portion of the Machine Robo toy line was exported and sold by Tonka in America as GoBots and Rock Lords. To date, only 15 episodes of the series have officially been released with English subtitles on three DVDs by Central Park Media.


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

Original video animations

Reina Stol in Wolf Sword Legend

When Revenge of Cronos left off, Rom and Reina had crossed a dimensional barrier. Their physical forms changed from robot to human, and they were separated, with blurred memories. Reina 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.

Lightning Trap - Leina & Laika

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 games

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.
