The Umbrella Academy on Netflix follows the story of seven children adopted by billionaire Sir Reginald Hargreeves (played by Colm Feore), who form a group of crime-fighting anti-vigilantes. As the Academy, which consists of characters including Luther (Tom Hopper) and Klaus (Robert Sheehan), grew up, they lost contact, until their dad died and they reunited for his funeral. His death remains shrouded in mystery until the end of the series, which has left many fans asking: Who killed the dad in The Umbrella Academy?

HOW TO WATCH THE UMBRELLA ACADEMY ONLINE The Umbrella Academy: Klaus tells Luther (Image: Netflix) Will there be another series of The Umbrella Academy on Netflix? The Umbrella Academy season two is yet to receive the green light by Netflix. Reginald Hargreeves’ death in the first season didn’t stop the character from appearing on the show in flashbacks, so Feore could appear once again should The Umbrella Academy be renewed. All six living members of the Academy managed to escape the apocalypse in the season finale, meaning there could be returns for Number Five, Luther, Klaus, Allison (Emmy Raver-Lampman), Diego (David Casteñada), and Vanya (Ellen Page). Their late brother Ben could also make a comeback in season two – how Ben died prior to when the Netflix series was set had viewers guessing throughout the first season. There may be returns for Pogo, Harold Jenkins/Leonard Peabody (John Magaro), and Cha Cha (Mary J Blige), but only in flashback form after all three died in season one. The Umbrella Academy is available to stream now on Netflix.All rights reserved for this news site express.co.uk and under his responsibility
