Add was a descendant from a family who studied Nasods and inherited their fascination with robotic beings. Despite losing his entire family due to investigating forbidden secrets, Add remained determined to learn more about the Nasods. He discovered an ancient library where he continued studying them until he invented the Nasod Dynamo weapon. Trapped in the library for a long time, Add eventually escaped and became ridden with insanity from isolation. Driven by his quest for rare Nasod codes, Add traveled through time to find them but found that the library's distortion had sent him far into the future where the Nasod race had already fallen. He tried to return to the past at first but changed his mind when he discovered traces of Eve.
