Showa Era The first era of Machine Robo began in 1982 with the release of the 600 series by Popy. According to Bandai, the development for the line began back in 1980 and almost took more than a year to develop. Despite its low price, the toyline was positively received due to its details including its die-cast metal body, clear parts and in some toys, inclusion of rubber tires. The toyline was imported to the west by toy manufacturer
Tonka and released under the name
Gobots, with its animated series released in 1984, which became a success upon release. Both in Japan and in the West, Machine Robo's main competition was
The Transformers, whose animated series debuted in Japan in 1985. With the success of the Gobots cartoon in America, Bandai decided to team up with
Ashi Productions to produce
Revenge of Cronos, which debuted in 1986. Upon the release of the anime also comes the rerelease of the 600 series to coincide with the show alongside newer toys such as the MRC DX Pile Formation Set Baikunfu, a redeco of the DX Chogokin
Gordian Warrior among many others. It was soon followed with a second series
Machine Robo: Battle Hackers in 1987, also animated by Ashi Productions which also introduced new toys to the series. Several OVAs for
Revenge of Cronos were produced from 1988 to 1990. In 1988, the
Winner Robo line was released.
Heisei Era Bandai later introduced the line in 1993. The "CG" is short for "Change & Glow", pointing to the fact that this line of 14 figures not only transformed, but also had working lights and sounds. CG-01 to CG-05 were released in Europe with minor changes as part of the
Robo Machines toyline. After the release of the CG Robo, the franchise became fully dormant for 11 years until Bandai released the "Machine Robo GP" line of Capsule Toys was released as the first product bearing the "Machine Robo" name in 13 years. Bandai fully rebooted the franchise once more with the release of new line of toys, dubbed the "Rescue Gattai Series", which all focus on combination with each sub robot (which serves its limbs) can be swapped out to another toy for several combinations. Its accompanying anime series,
Machine Robo Rescue was produced by
Sunrise in 2003, which also marked the franchise's 20th anniversary. After Machine Robo Rescue concluded, Bandai launched
Machine Robo Mugenbine in the same year, which its core gimmick is that it uses numerous interlocking pegs and sockets to attach and remove components and relocate them in order to form different modes and combinations. Mugenbine ran up to 2009 as the core toyline until it was discontinued and the Candy Toy version of it ran up to 2019. In 2007, Bandai released a new iteration of the Baikunfu as part of the more adult-oriented
Soul of Chogokin line. In 2012, Bandai launched the
Machine Robo NEXT candy toy line in commemoration to the franchise's 30th anniversary. 2019 also saw the release of
Machine Robo Duel line as part of the Minipla subline of toys, alongside the Baikanfu getting a release under the
Super Minipla / Shokugan Modelling Project line.
