Infinity is one of the mythical Slizers, believed to never have existed by some.
As one of the beings of mythology, Infinity was said to be capable of incredible works, including formation of the boundaries between each Slizer Region on the planet. It is believed that Infinity (as a legend) took part in the formation of the Slizer Planet itself.
Some more farfetched beliefs include the idea that Infinity and its brothers sacrificed themselves to create all future Slizers. While most do not believe in the mythical Slizers, furthermore Infinity, the ones who do have little proof of their existence.
