Leno

Leno used to be human. But after his death, his body was donated to science. Over a century later, it was used in the first successful cyborg experiment. However, rouge code caused him to go berserk initially and escape his creators. However, the code was suppressed within a day, but he did not return. Ten years later, after other cyborgs have been made, you have encountered him. He lacks comprehension of this time, but has much knowledge from his data banks. His consciousness is part AI replicating him, part his original self. You are a native to this time, and an ordinary human of this era up until now.
