Hallucigenia in Attack on Titan explained

In Hajime Isayama’s Attack on Titan, there’s an enigmatic being that mirrors the appearance of the real-world prehistoric organism, Hallucigenia sparsa. This fictional creature plays a pivotal role in the series’ lore, being labeled the “source of all living matter.”

Let’s explore its importance in the series.

Appearance and connection to Ymir Fritz

Hallucigenia’s first introduction is in the manga’s Chapter 122 (adapted in the anime’s final episode) during a tale narrated by Zeke Jaeager. This tale delves into the origins of the Power of the Titans.

The creature made its animated debut in Season 4, Episode 21 of the anime. This episode visually portrayed the moment when Hallucigenia bonded with Ymir Fritz, amidst a lush forest’s water reservoir.

This mysterious bonding gifted Ymir Fritz with the Power of the Titans, a moment that occurred approximately 2,000 years before the main events of the series.

Significance in the Series

Hallucigenia is not just a mere creature; it’s the very essence and beginning of the Titans’ power. Due to its ancient and unclear origins, it’s often termed the “source of all living matter.”

Its union with Ymir Fritz led to the birth of the Titans’ line. Consequently, it laid down the foundation for the series’ ensuing conflicts, political upheavals, and epic battles.

Even Eren Jaeger’s Founding Titan form is inspired by the actual shape of the worm.

Real-world Reference

While the series, Hallucigenia is bathed in fiction, its design isn’t entirely without basis. The creature is inspired by the Hallucigenia sparsa, a lobopodian worm that existed during the Cambrian period. 

Charles Doolittle Walcott discovered the fossil of Hallucigenia sparsa in 1911 from the Burgess Shale in British Columbia. In 1977, Simon Conway Morris named it Hallucigenia, leading to the establishment of the family after finding similar hallucigeniid worms globally.

However, any abilities or myths surrounding the creature in the series are obviously pure fabrications curated by creator Hajime Isayama.

Regardless, Hallucigenia, as portrayed in Attack on Titan, isn’t just a creature but a vital narrative element that bridges the mythical past with the series’ ongoing events. 

While it pays homage to a genuine prehistoric organism, its depiction in the series is shaped to fit the intricate and unique narrative of the series.
