Data Evolution:
Z Gundam Tenfold Enjoyment Book
> Back to Data Evolution


Mobile Suit Z Gundam Tenfold Enjoyment Book, published in May 1985 as an "emergency special issue" of Kodansha's Comic BomBom magazine, was created as an introduction to the recently launched Z Gundam series. As well as setting and production materials, a brief interview with director Yoshiyuki Tomino, and an overview of the Mobile Suit Variation and MS-X series, it includes a Universal Century timeline based largely on Tomino's Mobile Suit Gundam novels.

This U.C. timeline, described as "a complete series chronology to understand the old and new works," was compiled by Masaya Takahashi of the "Stream Base" modeling group. Takahashi was also the writer of the comic MS Senki and, later, the Gundam Sentinel photonovel. A translation appears below.

Translator's Note: This timeline includes almost all the historical dates and events from Tomino's novels, though some of the timing is adjusted to match the ages of the characters in the anime, and lists the events of the original Mobile Suit Gundam TV series without precise dates. I've added some annotations on individual items.

  Operation V starts.
  White Base docks at Side 7.
In order to gain an advantage in space strategy, where they lagged Zeon, the Federation Forces had carried out a project to develop mobile suits and new warships to operate them. First, two units each of the Gundam, Guncannon, and Guntank whose development was led by Tem Ray were brought to Side 7. Here they were assembled and adjusted, and underwent final tests. Tem returned to Jaburo with the satisfactory results. He then headed back to Side 7 aboard the White Base, constructed by Engineering Colonel Seki's team, to collect the three mobile suit types. The ship was meant to return to Jaburo carrying six fully equipped and operable mobile suits, but it was discovered by Lieutenant Commander Char. Having lost its regular pilot, the Gundam accidentally ended up becoming Amuro's machine.
  White Base heads for Luna II (Luna II escape operation).
The three types of RX-series mobile suits are loaded aboard the White Base, and Captain Paolo, who was headed for Jaburo, entrusts the ship to Bright and the other boys and girls. The White Base now leaves the regular Federation Forces chain of command, becoming an extra unit, and heads for Earth.

Translator's Notes

(1) The formatting of the published timeline is a little confusing here, as the year "1979" also appears above this text, but I think this must be an error.

(2) This information is from the timeline in the original setting notes.

(3) Char is 20 years old in the Mobile Suit Gundam anime. In Tomino's novels, he appears to be a little older; most likely he was born around U.C.0057, making him the same age as Garma Zabi.

(4) Garma is 20 years old in the Mobile Suit Gundam anime. In Tomino's novels, we are told he was eight years old when the Principality of Zeon was established in U.C.0065, so presumably he was born around U.C.0057 and is now about 22 years old.

(5) Sayla is 17 years old in the Mobile Suit Gundam anime. In Tomino's novels, we are told she was three years old when Zeon Deikun died in U.C.0062, and is now 20 years old, so presumably she was born around U.C.0059.

(6) Amuro is 15 years old at the beginning of the Mobile Suit Gundam anime. In Tomino's novels, we are told he is one or two years younger than 20-year-old Sayla, and that he was separated from his mother at age six. The latter date may correspond to the start of Side 7's construction in U.C.0067, suggesting that Amuro was born around U.C.0061.

(7) Tomino's novels offer conflicting information as to when Char entered Zeon. At one point we're told it was in U.C.0070, but elsewhere Tomino writes that he separated from his sister seven or eight years ago, which would be around U.C.0072. We're also told that Char entered Zeon at age 15 and enrolled in military academy at age 18, and those claims appear to be the basis for the dates used here.

(8) This ship is also mentioned in the game book "The Last Red Comet," published in May 1986, but this appears to be the first published reference to it.
