This is the only "Earthbound Immortal" to never have been a Featured Card in Yu-Gi-Oh! 5D's.
Furthermore, Although the other Immortals were picked on the "Card of the week" by Leo and Luna (Japanese version, before the episode starts), this is the one Earthbound Immortal that was never chosen.
This card's design is based on the Hummingbird geoglyph of the Nazca Lines.
"Aslla Piscu" comes from the word "Piscu" which in Latin means "fisherman" but erase the "s" and it becomes "Picu" which stands for "hummingbird". Aslla has no translation in Latin.
This is currently the only card that has a word (other than the, of, on, to, etc) in its name, that doesn't have its first letter capitalized, as it should be to all words in cards' names, except the, of, on, to, etc.
It is one of the two Earthbound Immortals to speak in the anime
It is also the only Earthbound Immortal to speak a total of three times (once in Carly's flashback, Another while possessing her to continue the duel, and the final time is speaking through her).
