Trivia

 * "Valkyr" is derived from Valkyrie. According to Norse Mythology, the Valkyries were a host of divine creatures in service of the gods that brought the "chosen" among the fallen up to Asgard (where the gods resided). It was generally believed that dying in battle with your honor intact was a sure way of being chosen.
 * She is the second female Warframe whose base stats defy a trend of fragility; despite having low shields she has the highest armor value out of all the Warframes.
 * Both her Warframe Profile video and in-game description state that she's a product (or possibly a failure) of the Zanuka Project.
 * Valkyr is the only Warframe which has human-like audible cries, voiced by the Digital Extremes community coordinator, Megan.
 * Valkyr is the 2nd Warframe to replace Alloy Plates with Circuits when building. (The 1st was Saryn.)
 * Valkyr is the most robotic-looking of the Tenno, possibly due to her being experimented on with Corpus technology.
 * Valkyr is one of the two Warframes that were made in the current time period. Almost all of the other Warframes were made during the Great War with the exception of Nova who is said to be a recently developed Warframe under the Tenno Council. Valkyr was, however, an existing but unknown Warframe herself before being experimented on.
 * Valkyr in many ways resembles and may be based off a feline, if only vaguely:
 * Hysteria gives Valkyr a set of claws.
 * An alternate helmet, Bastet, is named after an Egyptian Cat-headed Goddess of Home and Family.
 * Equipping a whip (Lecta or Scoliac) while using Hysteria gives the appearance of a tail, though it may possibly be just a bug.
