- It is also a homophone of "hertz", a unit of measure for cyclical actions which is defined as how many times an event occurs per second. Heartbeats can be measured in hertz.
- This monster appears in the artwork of "Cyber Revsystem", being clad in "Cyber Dragon's" armor to create "Cyber Dragon Sieger".
