Doomsday Creators (The Umbrella Academy)

The 10 Hardgreeves siblings have never had an easy life, growing up with super powers, and a neglectful father.
Only 6 of them actually make it into adult hood, as the rest are lost along the way. Or so they all thought.
When the siblings come together to mourn the death of their father, their brother number Five suddenly reappears and reveals that the world is going to end in 8 days.

Lucy Hargreeves, never really fitted in with her siblings, so when Five returns she is over the moon to see him, as he always used to be her favourite brother.
When he tells her about doomsday, she is desperate to help him stop it, but she knows that deep down her powers are not as good as everyone elses. She also knows that if she uses them too much, she might slip into a coma, and never wake up again.
