Diego Hargreeves

Diego Hargreeves, originally designated as Number Two, 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, Diego was Hargreeves' Number Two with the power to manipulate thrown objects such as knives while in flight. After Five failed to avert the apocalypse, Diego found himself transported to Dallas, September 1, 1963. After publicly claiming that JFK will be assassinated, Diego found himself locked up, but broke out of the hospital with his newfound friend, Lila, for whom he later began to develop feelings. Diego attempted to save the day — and the president — all on his own in an effort to show the Umbrella Academy he is worthy.

Diego is a sweet but impulsive and brash individual with a tendency to show off. However, beneath his confident, cocky behavior lies a deeply insecure individual who desperately wants to prove himself. He had a sibling rivalry with his brother Luther, over being number one. He has a deep emotional connection to his animatronic "mother", more so than his siblings. As such, he is fiercely protective of her even going so as to throw evidence away that could possibly implicate her in his father's death. Diego meets a human Grace in 1963, he is shocked but happy to see she used to be real, however with his obsession with saving president Kennedy he sees Grace again and warns her about Reginald plotting to kill the president, initially Grace thinks it's nonsense but then grows suspicious of "Reggie". Despite his tough exterior Diego has shown to be very caring about his family, especially Klaus whom he was close to when they were children, Diego urges Klaus to stop doing drugs and alcohol. Diego also seemed to be close with Ben before he died. Throughout the seasons Diego becomes more mature and no longer fights with Luther, he also grows to be supportive of Viktor whom he used to mistreat in the past, especially when he comes out as transgender. By season 3 Diego shows a deep care and affection for all his siblings, even Allison. Diego grew to love Stanley as his son very quickly but Lila lied to him about being his son to test his fatherhood skills since she is actually pregnant. Diego is considered by many to be unintelligent. Diego often shows moments of ignorance (such as calling the Hadron Collider "Hard-On") and frequently makes reckless (if not outright foolish) choices. However, he often shows a surprising degree of insight.
