There Are Elements In The Comics Not Used In The Umbrella Academy Season 1
The Umbrella Academy comics won't be irrelevant, though. The Umbrella Academy season 1 may have exhausted the plot of the comics, but there are still several themes and ideas that could be tapped into. The most obvious is the existence of extraterrestrial life. In The Umbrella Academy comics, Sir Reginald Hargreeves himself was actually an alien who had disguised himself as a human being, which neatly explained his mysterious depths of knowledge and insight; Hotel Oblivion introduced Hargreeves' vessel, the Minerva, which was capable of interstellar flight. There were other aliens, too. In fact, in The Apocalypse Suite, Luther was staying on the Moon because he really was needed to defend the planet from alien invaders. It's certainly possible that The Umbrella Academy season 2 could involve aliens. Is that any less fantastical than time travel or... Pogo?
Meanwhile, Umbrella Academy season 1 has left an important question unanswered: what happened to the rest of the 43 children who were born on that fateful day years ago? Sir Reginald Hargreeves only managed to acquire seven of them; while several would have died due to complications during the birth, a lot of them will have survived, and will still be out there. Gerard Way used this idea to explain the existence of super-villains in his comics, revealing that several of them had chosen to use their powers for evil. They included villains like the Murder Magician, a teleporter who called himself Obscura, and - most dangerous of all - a super-powered titan known as the Scientific Man. The Umbrella Academy season 1 didn't provide a hint as to the existence of any of these other super-powered individuals, but they could well be introduced in The Umbrella Academy season 2.
What Can We Expect From The Umbrella Academy Season 2?
Netflix is yet to officially renew The Umbrella Academy for a second season, but it's surely only a matter of time. It's currently the most in-demand superhero show in the United States, beating every Marvel and DC TV series. Given the amount of time it takes to make an effects-heavy superhero TV series, it's reasonable to assume The Umbrella Academy season 2 won't release until 2020, at the earliest.
Naturally, the plot will pick up exactly where season 1 left off, with the Umbrella Academy emerging at some point in history and attempting to reorient themselves. There are clearly going to be physical impacts from the time travel; the students appear to have de-aged back to teenage form, and it's even possible Ben will have effectively been resurrected. But it shouldn't be assumed that they'll be stuck in their younger forms with all the knowledge of their older selves. The Umbrella Academy season 1 warned that time travel can affect the mind as well as the body. It seems more likely that the siblings will be rather confused, setting up a dark plot where they're once again attempting to avert an apocalypse they don't truly understand.
There's a solid chance that the Umbrella Academy will have traveled back to a time when their "father," Sir Reginald Hargreeves, was still alive; there are still two many mysterious surrounding that character for the show to simply move on from him, and revealing the truth through his past self would be a nice touch. Meanwhile, the Commission is sure to return, working to ensure the end of the world happens and the Umbrella Academy are unsuccessful in changing the past. All this leaves a lot of room for fresh ideas to be woven into the story - perhaps even including some of the concepts that are present in the comics, but not in The Umbrella Academy season 1.
The Umbrella Academy season 1 is streaming now on Netflix.
