Raimi was one of the 17 Specters sent in secret by Wyvern Rhadamanthys to attack Athena’s stronghold, Sanctuary. When the group reached the Temple of Leo, five of them were immediately killed by its guardian, Leo Aiolia. As the other Specters continued their attack, Raimi saw this as an opening and entangled the Gold Saint, claiming him to be his victim. However, the Specter underestimated Aiolia and after sending the other Specters to the next temple, Raimi was soon killed by the Leo Gold Saint.
The Worm Specter in the 18th century also appears briefly in Next Dimension, battling against Leo Kaiser, whom he is unable to defeat, and the Specter is ultimately defeated by Cancer Deathtoll with an humilliating attack. The name of the Worm Specter in that era was not revealed by Kurumada, although he wears the same Surplice and his appearance is identical to Raimi’s.
