A mechanical centipede-like creature, Ouroboros is born from the merging of the 24 Kazakh Officers. The leading officer, General Mikiel, takes on the form of its head and torso, while the other officers all jump behind him to transform into the various 2-legged segments that form part of its large body. It attacks by flying in circles around the chamber, trying to hit its target with its two main weapons: a three-way beam cannon found in its head, and a hammer and sickle combination held in its hands, both part of a known Communist symbol.
StoryEditHiryu starts his mission to stop Grandmaster Meio's plans by infiltrating Kazakh's capital, and eventually reaches the chambers of the city's government officers. Upon Hiryu's appearance, General Mikiel gives a hand gesture and all officers jump into the air, to combine and create Ouroboros. Despite its large size and strength, Ouroboros is eventually destroyed by Hiryu.
Later, during Hiryu's final assault on the Third Moon, Ouroboros is ressurected by Grandmaster Meio's power. However, it instead ends up helping Hiryu reach the final area where Meio is awaiting, before being destroyed a second time.

In the first fight, Ouroboros mostly follows Hiryu around the spacious area, moving in a circular snake-like pattern, while swinging his two weapons and shooting his three-way cannon. If Hiryu remains close to it, sometimes Ouroboros will start moving in circles close to him. Hiryu can also ride atop Ouroboros and strike him from behind, but its constant circling movement makes it hard to stay in place. It can also start moving in reverse in order to shake Hiryu off.
During the second fight, Ouroboros is immune to damage at first, as it's impossible to reach the area of the final battle with Grandmaster Meio without it. Once a platform to stand on is reached, Ouroboros starts circling in place, now vulnerable to damage. Despite still attacking with all its weapons, it can still be easily destroyed.
Ouroboros' concept was based off an old children's book Isuke used to enjoy, while its name and general serpentine appearance are taken from the ancient symbol representing eternity and immortality. The move in which Ouroboros flies around itself forming a perfect circle references the symbol's most recognizable representation: a snake biting its own tail.
This monster is well known as one of the most outlandish and unique designs in the original game, helping shape up its distinctive feel. It has served as inspiration to similar boss enemies in the series, being succeeded by the Emperor Dragon in Strider 2 and the Ouroboros Mk.III in the 2014 Strider.
He's shown being capable of talking in the pre-battle screen, presenting itself by name and repeating "Quiz!" two times.
