The Italian version, Jeeg Robot d'acciaio (Jeeg Robot of Steel), featured a rewritten theme song that became iconic. The lyrics "Jeeg, Jeeg, Jeeg, Jeeg Robot / Spaziale, Spaziale..." are instantly recognizable to anyone who grew up watching European television in that era. This Italian localization was the version syndicated to other countries, influencing how the show was presented in the Eastern Bloc and the Middle East.
