A descendant of a family that studied Nasods, Add is an intelligent mechanic who had inherited the fascination for the robotic race. When his entire family was captured and slain for investigating the Nasods' forbidden secrets, Add was forced into slavery. While trying to escape, he fell into an ancient library and was trapped for a long time. Here, he continued his study of Nasods and in due time, he invented a weapon called the Nasod Dynamo. He eventually used the weapon to escape the library before it could collapse on him.
Ridden with insanity due to isolation, Add took to the road to find rare Nasod codes, but discovered that the library's time distortion had sent him far into the future when the Nasod race had already fallen. He tried to return to the past at first, but he found himself intruiged by this time and decided to stay, after all, there were experiments to be done.
