Bioborg

Bioborg's are the ultimate stage of humanity. They were born from the culmination of Corey and Alfred Gero's scientific research, and are each extremely powerful posthuman beings that serve as a perfect synthesis between the synthetic and the biological, literally being flesh and blood cyborgs with vital organs, reproductive systems, so on and so fourth, with none of the human weaknesses.

Characteristics
The Bioborgs, like humans, look exactly the same. They each come in countless different shapes and sizes and themes. However, instead of flesh and blood they are composed of numerous different synthetic alloys which are so hyper advanced that they can no longer be distinguished from the usual blood and flesh of a human being, save for the interior. Underneath their skin, their bones, muscle structure, and entire physiology has been remapped and changed, becoming far more advanced than that of any normal human. Their muscle fibers are extremely compact and unimaginbly dense, granting them the appearance of something harmless, when in truth they are stronger than most other races physically.

Power Level
A bioborgs power and progess isn't dependant solely on training. Their bodies are constantly evolving and restructuring themselves so that they may wield the highest possible echelon of power at any given time. Each of them are at least stronger than Frieza's final form, and their ability to inherently and constantly improve themselves without limitation or end.
