Within the angelic hierarchy, feathered serpents are '''C-rank''', ranking above [[angel|angels]] and [[pterolykos|pterolykoi]], at the same level as [[shrine maiden|shrine maidens]] and [[guardian angels|guardian angels]], and under [[seraph|seraphs]].
Feathered serpents are unique creatures; though they cannot speak, they are highly intelligent and capable of understanding any language, and possess magical abilities in three distinct domains. They can fire ''airblasts'' much like a [[draconair]]; ''psi-blasts'' much like a [[psionic warrior]] or a [[satori]], and one angelic power unique to this creature, the ''seraphic speed'' techniqueangelic power (borrowed from [[seraph|seraphs]]), which allows them to spend some of their accumulated Angelic Energy to make themselves even fasterthan normal.
Like [[pterolykoi]], feathered serpents are non-evolving and not considered sapient. However, their psionic abilities have long been the subject of a debate on whether these creatures are capable of reading minds, in much the same way [[satori]] can. Heaven, Ltd. has so far refused to speak out in an official capacity on the subject, but this theory is considered plausible by the scientific community, with many stories and anecdotes supporting it and claiming it to be true.
