Readers of the graphic novels have already met a version of the Sparrow Academy, but if you're purely a series watcher, you might be asking who these six (minus Ben, since we already know him) are. Luckily, "The Umbrella Academy" showrunner Steve Blackman is shedding some light on the matter. In an interview with Inverse, Blackman made sure to note that the mysterious six siblings are "new people." "They're not our characters," he said. "They are different people, and that's all I can really say."
For those who need more context, the Sparrow Academy has been introduced in the Gerard Way-penned graphic novels and will be heavily featured in the next book. Way told Forbes that volume four of the series will be called "Sparrow Academy" and deals with "a very big reveal in the 'Umbrella Academy' universe . . . and our siblings learn a lot about what was happening behind the scenes, as well as discovering the true nature of some characters that have been with them since the beginning."
He added, "The series finally starts to answer the question: 'What about the other babies born on that day, in that moment?' The 'Umbrella Academy' siblings are not alone in the world anymore."
Sounds ominous, doesn't it? Well, the "Sparrows," as they are called, make their first appearance in "The Umbrella Academy: Hotel Oblivion" and don't seem like they're meant to be rivals to the Hargreeves at all. One of them refers to Luther as a brother and they appear to be present to help deal with a villain crisis, so it's safe to assume that they're also a group of the 43 children born under curious circumstances on Oct. 1, 1989, and don't mean any harm to their "siblings."
How that translates to the Netflix series is the real question.
