"Evilswarm Castor" is missing the red Evilswarm emblem normally present on his hip-plate. The significance of this, if any, is unknown. It could be that, as the card's name suggests, "Evilswarm Castor" is being purified and being reborn to his former self before being corrupted by the Evilswarm virus.
The inclusion of "Constellar Rasalhague" may allude to Asclepius, who in Greek mythology was a healer who ascended to godhood after he began resurrecting souls, but was smote for the crime against nature.
This card's Japanese name could be a pun on the word "Supernova" (超新星 Chōshinsei).
