The series marked the franchise's switch from Columbia Music Entertainment to Avex Group, which continues to produce music for the Kamen Rider Series today.
This was the first series to feature outright evil people who became Kamen Riders.
Producer Shirakura originally wanted a staggering 50 riders to appear, basically one every episode. Director Ryuta Tasaki responded that it was a "tough request. Thinking about just suit costs, what about 13?" In are recent talk show,
Shirakura remembered the story, but could not help but wonder "Why is the director worrying about suit costs?"
The first series to explicitly feature a variety of animal motifs, which would later also happen in OOO, Build, and Zero-One.
Kamen Rider Zolda's name is derived from the German, French or Russian word, "soldat" meaning "soldier" or "mercenary".
