Diaclone is a joint American-Japanese anime series. It is based on Takara's Diaclone and Microman lines, which provided the molds for the original Transformers toys. The series premiered on WBC (Western Broadcasting Company) on Labor Day 2014, and will premiere on TV Tokyo on Christmas Day. The scripting and English voices are handled by WBC (with the voice cast being a combination of Johnson's own in-house voices, FUNimation, and Bandai), while the Japanese dub is handled by TV Tokyo, and animation by Toei. The series is banned in Germany due to its use of the Nazis as the villains.


The series takes place in an alternate 1980s. In this timeline, the Nazis won World War II, conquering all of Western Europe (except Britain) and eventually invading the United States. This invasion was swiftly pushed back, followed by a Spanish invasion of former Southern France, starting the Spanish-German War. Meanwhile, Japan still loses in the Pacific, and the atomic bombs are dropped on Hiroshima and Nagasaki, but the United States does not occupy Japan. Hideki Tojo remains in power, which causes a massive civil war that was won by the Rebels in 1962.

Following the war, Japan saw massive breakthroughs in robot technology in the 1970s. Working hand-in-hand with the United States, they created large, transforming, one-pilot robots that replaced the JSDF in 1979. Unfortunately, some of the designs were stolen by German spies, who now have robots of their own and are using them to wage war with the United States and Japan, the last remaining superpowers after the United States defeated the Soviet Union in World War III following the Cuban Missile Crisis (a one-sided war in which the USSR was unable to deliver even a single nuclear bomb because of their aging bombers, improperly-built delivery systems, and unreliable ICBMs). The USSR was disbanded, Russia was restored, made a democracy, and is now an ally of the United States and Japan.

The series focuses on a joint Japanese-American taskforce of "Car Robots". These robots are piloted by "teens with attitude" and are led by Paul Popper, pilot of Battle Convoy.


Note that all robots on both sides are mass-produced; the robots in this article are the specific robot within each unit.

Car Robots

The Car Robots are a special forces unit of the Japanese-American Mechanized Forces. They are the main protagonists of the series and fill the role of the Autobots.


  • Billy Holland (Bryce Papenbrook) - The main protagonist of the series. Bill is a rookie pilot from San Francisco who was forcibly enlisted by his abusive parents who consider him an "accident". Billy doesn't want to be a pilot, yet he is aware of the threat posed by the Germans. He soon finds he is a natural at piloting, and has the uncanny ability to one-shot his opponents (a "critical hit", in his words). Since he joined, Billy has become an outgoing pilot who seeks to rid the world of the Germans.
  • Hikari Mihama (Stephanie Sheh) - The deuteragonist of the series. Hikari was the only person besides Paul Popper to show any form of civility towards Billy when he arrived. A kind, soft-spoken girl, Hikari is often paired with Billy on missions. She has a major crush on Billy that she struggles to tell him about, but is too shy. This goes both ways, believe it or not, as Billy also has a major crush on Hikari. This has not escaped the attention of the shippers, who pair the two in fanart and fanfiction.
  • Paul Popper (Ron Perlman) - The wise leader of the Car Robots Force. When Billy arrived, he saw great potential in him and scolded the other pilots (bar Hikari) for their hostility towards him. Paul leads the Car Robots into battle against the Reich Changers fearlessly and without breaking a sweat.
  • Shinji Hotaru (Spike Spencer) - Very much like Evangelion's Shinji Ikari (right down to the first name and voice actor), this Shinji is also a shy, nervous, non-confrontational person who just wants to lock himself away from the rest of the world. But when duty calls, look out for him to be a fierce warrior who gallantly defends his country!
  • Miku Tenzen (Kristen Schaal) - The very definition of a Genki Girl, Miku has boundless energy that she directs into either annoying people or blasting German robots. She is the master of beer pong, since she seems immune to being drunk.
  • Ed Bigby (Frank Welker) - Based on the Machine Wars character, Ed is the bully of the group. He is the personification of hatred, as he always beats up Billy. But many times, he is foiled by Hikari, whom he is scared of.
  • Shuta Go (Josh Grelle) - Yes, it's THAT Shuta. He is something of an action-hero who also has a ton of modesty.
  • Minerva (Caitlin Glass) - ALSO that Minerva! She is Shuta's partner and girlfriend. Daughter of a US Senator, she is a pilot only to boost her dad's approval rating.
  • Mel Gibbs (Johnny Yong Bosch) - Obsessed with British cinema, he often quotes James Bond films and loves The Railway Series, even having his own model railway of Thomas' Branch Line.
  • Mark Hart (Corey Burton) - A hypochondriac who spends half of his time in First Aid and the other half in his sterilized cockpit.
  • Jenny Sullesburgh (Karen Strassman) - A walking, talking encyclopedia (much like Strassman's best-known character, Miyuki Takara of Lucky Star), she can identify any type of robot, weapon, and other systems with extreme accuracy. Rumored to have Asperger's Syndrome, a fact she'll never talk about.
  • Kensuke Takara (Ian Sinclair) - A guy who think's he's cool, but is perpetually stuck in the 1960s. Talks like a hippie.
  • Itsuki Tanizaki (J. Michael Tatum) - Obsessed with the paranormal, including ghosts, aliens, time travellers, espers, and cryptids.
  • Minamo Ayanami (Michelle Ruff) - An emotionless girl (as if her first and last name didn't tip you off). She fights with clinical efficiency and has no sense of humor. None at all.
  • Jason Stiletto (Christopher Sabat) - A condescending pilot who looks down upon his comrades with great disdain. Believes he is the greatest person who ever lived, but is really just an insecure crybaby.
  • Lee Johnson (R. Lee Ermey) - A former drill seargent who takes everything a little too seriously.
  • Kirito Mazuka (Crispin Freeman) - A deadpan snarker who points out all the absurdities around him. Considered a mouthpiece for the fandom.
  • Kaito Hajime (Doug Walker) - A man in his 30s who criticizes every little thing he finds wrong, from movies to TV shows to the way weapons are constructed. Makes everybody laugh.
  • Other Pilots - You think I have time to make up names and bios for each pilot? Let's just say there's like 40-something pilots and leave it at that.
