* This card gets its name from [[wikipedia:Ragnarök|Ragnarök]]; a series of future events that eliminates the world's occupants, before renewing it and repopulating it in Norse mythology.
* This card's name contains a pun similar to that of "[[DDD D/D/D Hell Armageddon the Cruel End Overlord]]": "Kaichiō" (壊薙王) sounds like "Kaichō" (会長), which means "chairman".
