Ultraman Wiki

The Heller Empire (ヘラー帝国 Herā Teikoku) is an empire established by their namesake leader, serving as the antagonist faction for the 14 final episodes of The☆Ultraman.



10,000 years prior to the series, Heller and his 3,000 followers were banished from Planet U40 by its ruling council when he voiced his intent on using the Ultra Mind towards those of immortality. Within the dark nebula, Heller Empire was established as they built their military forces over time.


Heller Empire commences their attack on Planet U40 as revenge of their banishment. In addition, countless planets have fallen to their might, such as Planet Fedelico and Planet Gilo to name a few. To cement their victory, Heller Empire established Heller City (ヘラーシティ Herā Shiti) as their base of operations.

When Amia flee to Earth to warn her brother Ultraman Joneus, Heller sent his trusted lieutenant Roygar to command a fleet of ships to pursue Amia, tracking Joneus and secure/destroy the ancient U40 battleship Ultria on Antarctica. Their objection failed due to the siblings' persistence and mankind's assistance in countering against the invasion.

By setting up Titan Base (タイターン基地 Taitān Kichi) on Saturn's orbit, Roygar overseers the invasion on Earth using various forces of Heller Army, which includes deceiving aliens to their bidding. Under Heller's orders, the army attacked Earth to prevent mankind from interfering with their affairs against remnants of U40's forces. By slipping into their ranks, Amia managed to convince the Science Guard Party into joining the fight but she was kidnapped during the assault on Titan Base and brought to Heller City on U40. As the conflict against U Fleet ensues, Heller captured the Science Guard Party and trapped the Great Sage into a data disk for safekeeping while abusing the Ultra Mind's power into a cannon to eliminate opposing forces. Choichiro Hikari escaped to re-merge with Joneus and rescue his teammates before Makdatar could execute them with the help of Elek and Loto. As the entire 8 great warriors attacked Heller City, Heller attempted to escape by jettisoning the city but Joneus interfered to rescue Amia and the Great Sage. Heller died when his namesake city crashed into the ground, therefore disbanding his empire once and for all.

From Ultraman Titas' recollection, his parents were soldiers of Heller Empire and conceived him during their banishment into dark nebula. Despite their dedication to their leader, they sent an infant Titas to U40, believing that he deserved to be raised differently from their path. The★Ultraman Titas - Part 1 Titas was part of a faction of rebels fighting against a portion of the Guar Empire's army in a nearby area from Heller City. Kishiader was unleashed to kill the rebels, including the captain Grigoreos and Titas' friend Mattia. This gave him the push to transform for the first time and kill the space monster with Planium Buster. The★Ultraman Titas - Part 3


Heller and his other 3,000 U40 dissidents discarded their Ultramen forms for eternal youth. Although they are by no means an "Ultra Kaiju", the 2013 Ultra Monster Photobook proclaims them as Anti Ultra Humanoids (反ウルトラヒューマノイド Han Urutora Hyūmanoido).
