Super Saiyan Aleph

Super Saiyan Aleph is a hypothetical transformation or the single Saiyan exists in a higher level of reality. Just known that the form is the strongest transformation in the universe. It's firstly introduced by Genesis as a hypothesis. It then had become a infamous legend across the world until it was forgotten after thousands years.

Overview
"We, normal Saiyans' strength is measured by the height of this world we are living... As an Aleph Saiyan, that Saiyan was a mere mortal who had come to "the beyond realm". The one who had challenged all limits, all levels and transcended all of those."

Since the transformation is just a hypothesis. Therefore, there is no way to attain the legendary Super Saiyan Aleph. Or not. The form is described as a ultimate limit of the Saiyan, based off the limitless potential of a Saiyan. The omnipotent, all-mighty, limitless god. Beyond all the concepts of space, time, dimension, life, death, all numbers, all existences. The Saiyan who attains this form exists from an even higher world, viewing all of beings as pieces in a game broad.
