Ben Hargreeves

Ben Hargreeves, originally designated as Number Six, is one of the forty-three children who were all born on the 12th hour of the first day of October 1989 to mothers without any previous signs of pregnancy. The baby was one of seven adopted by Sir Reginald Hargreeves with the intention of training them to save the world. Ranked by their individual usefulness, Ben was Hargreeves' Number Six as a member of the Umbrella Academy. He possessed the ability to summon eldritch creatures through a portal to another dimension located in his body. Ben's death is one of the main reasons that the Academy disbanded.

Transported to February 11, 1960 with Klaus, Ben was determined to be seen by those he loves and vowed to go further than ever before to make his presence known. It was Ben who ultimately saved the world by sacrificing himself to calm Viktor down. After stopping the apocalypse, Ben's ghost moved on to the afterlife.

Ben is a very introverted person. While he was dead, he was scared to go into the light and spent time hanging out with his brother Klaus. It often became exhausted for him to watch and supervise his brother, due to Klaus always acting very volatile and harming himself. Ben cares very deeply for Klaus, and had FOMO for the real world. This is proven true, when Ben begs for Klaus to let him possess his body. When Ben is possessing Klaus, he is very happy and extroverted, revealing a side to him none of us have really seen before, He feels happy and freed from all the limits. When he reunites with Diego, they both burst into tears due to Ben's death a long time ago. Ben's usual personality is very stoic because he's always accompanied Klaus, caring and watching over him. This exhausted and drained him. But deep down he is a very happy person who is willing to care for his brother.
