This card has the shortest effect text of any monster in the TCG (Errata'd card).
This monster's crown in its TCG artwork is the exact same crown as the one "King Fog" possesses.
Despite the card artwork not showing this monster's body, the anime and its Capsule Monsterspiece, shows this card to have a body.
All of this monster's TCG names are a portmanteau of the words for "skeleton" and "angel", except for the Italian name simply meaning "Skeletal Angel". Ironically, it has anything but a visible skeletal structure. Its Japanese name is a pormanteau of 透ける (sukeru "to be invisible") and エンジェル (enjeru "angel"). The Korean name (스켈엔젤 Seuker-enjel) probably uses the English pun, while the Chinese name (隱形天使 Yǐnxíng Tiānshǐ) literally means "invisible angel".
