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.
 * 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 based off Corpus technology.
