Umbrella Academy Season 3 Ending Explained: What Happens To The Hargreeves Family?

gamespot.com:

Umbrella Academy Season 3 has arrived on Netflix, and the Hargreeves family is up to their usual antics of squabbling with each other and facing down a massive, cosmic-level threat that may or may not consume all reality. You know, regular dysfunctional family stuff. This season took things bigger and, somehow, weirder than ever before--and we don't say that lightly, considering Season 2 saw them time traveling the '50s and facing off with a group of Swedish assassins and also a man who was actually a sentient goldfish on robotic body.

We're going to break the whole thing down for you here, but please be warned if you haven't finished Season 3, there are major spoilers ahead--and most of them probably won't make a lot of sense if you're not at least mostly caught up on the Umbrella Academy as a whole. Please proceed with caution!

By interacting with their father in the past, they've inspired him to adopt better children--which is totally possible, after all, they weren't the only mystery babies to be born that day back in 1989. So the Umbrellas have been replaced by the Sparrows, a well oiled fighting machine who are basically better and more successful than the Umbrellas in every way. But there's a problem--the incongruities in time and space have created what Five calls a Kugelblitz, an anomaly that is growing larger and larger until it finally consumes all reality and destroys the universe.

Whoops.

So settling into their new lives isn't an option, the Umbrellas, with the reluctant help of the Sparrows, must figure out what's happening and stop the Kugelblitz--or just let it go. It turns out three back to back
