Cyborg Number One

Cyborg Number One, more often called "One" by his creators, is a highly advanced cyborg created by the enigmatic Doctor Tenma.

History
Very little is known about One's life currently, as during his reconstruction, One's memories were suppressed, his personality altered, and his identity erased. It is suggested that he was a fireman in life, and so it is safe to assume that he died on duty, before his body was collected and used in Tenma's experiment.

Memories
It is assumed that One regained his memory, which is what caused him and the other cyborgs to revolt, however he did not live long enough to share those memories. Because we do not know who One was before he became a cyborg, it is impossible to know whether or not anything of his original personality remained intact. Due to the striking differences between he and Cyborg Number Eight, it isn't necessarily safe to assume that their memories were altered to similar degrees or in similar ways.

Purpose
One was designed to be the ultimate rescue officer, able to operate domestically and on the battlefield. One was created to save lives and prevent disasters, however many of his life-saving features can also be used to kill.

Technology
One's body is on a scale of genius comparable to that of Tenma's other seven cyborgs, however, being the first of its kind, One's bulky frame and shoddy reasoning skills make him seem almost primitive in comparison to the rest of the series. It is important to note however that One can survive in conditions which the other seven cyborgs could not, and his durability is second only to Cyborg Number Two.

One is equipped with the ability to cool or heat the area around him to an incredible extent, nearly melting lamp-posts and asphalt during his fight with Eight. One is also equipped with powerful heating elements in his hands which were originally designed to melt snow and ice. One has modified these heating elements to reach incredible temperatures.

His body is designed to be bulletproof, resistant to extreme temperatures and rapid change in temperature, incredibly durable, and able to withstand great weight and pressure. It is also waterproof.

As with all of Tenma's cyborgs, One's left forearm houses a small memory bank which acts as the equivalent of a flight recorder. This memory bank is designed to be able to endure incredible damage and extreme conditions, and is infallibly the last part to fail on Tenma's designs. By his own account, the data stored on the black boxes will outlive him.

Like the other cyborgs in the "series", One seems to run on Mako, and can store large amounts of it within his body.

Trivia

 * One's body was much cheaper than Eight's, however it still cost Tenma a fortune.
 * One does not possess a "foldout" form, but is instead one of the few single-form and single-purpose cyborgs.
