Grosse Augen, also known as "an Ally of Humanity", is an alien that is a giant in size unless it merges with a human, at which point it can change between the sizes. It has many psychic powers. One part of the media supports it.
Jirou ends up finding the host/human that contained Grosse Augen but disobeyed the orders of the Superhuman Bureau in order to let the human host live after Grosse Augen had been released.
- Grosse Augen's name means "big eyes" in German. Jiro named it this because of the large eye it has on its chest.
- Grosse Augen's origin story of an alien who merges with a human to fight evil giant aliens is a reference to the origin of the original Ultraman.
