Credence Barebone

Credence Barebone is one of the antagonists of the 2016 fantasy film Fantastic Beasts and Where to Find Them. Crednce was the adopted son of Mary Lou Barebone, leader of the anti-witch No-Maj group the New Salem Philanthropic Society. Shy and withdrawn, this caused Credence to be susceptible to her abuse.

Early Life
Sometime before the events of the film, Credence was born to an unnamed witch prior to being adopted by Mary Lou Barebone, the fanatical leader of the New Salem Philanthropic Society. Whilst under her care, Credence was physically abused by the deranged woman as to suppress his magical abilities. Her frequent abuse of her adopted son would cause him to become arguably the most powerful Obscurial in the Harry Potter universe.

Present day
By 1926, Credence had been losing control of his Obscurus, which was running amok in New York. During that time, Credence had gotten into contact with Gellert Grindewald, who had been masquerading as Percival Graves, the head of the Department of Magical Law Enforcement (MACUSA). Gellert requests that Credence help him search for the obscurial child in the Second Salem Church, stating that he'd help Credence realize his potential in return. After the Second Salmers fail to garner support from Henry Shaw Senior, as well as being insulted by Mary, Credence's Obscurial breaks loose, and wreaks havoc on the City Hall fund-raising dinner, killing the senator as a result. This act unwittingly exposes the wizarding world.

The next day, Mary discovers a wand, and immediately includes that it belonged to Credence. As she was preparing to beat him yet again, Modesty speaks up, insisting that it was hers. She pries the belt from her adopted mother's hand, which causes Credence's Obscurus to manifest. The Obscurus mauls the fanatical leader of the NSPS to death, but it also ends up killing Chastity, and heavily damaging the house. Grindelwald arrives, demanding that Credence lead him to Modesty, who had escaped the destruction of her home. Once there, Grindelwald betrays him, saying that he no longer needed him. Angered, Credence reveals his Obscurial form, much to the astonishment of the infamous wizard. Despite insisting that he'd train him, it was too late for Credence, and he goes on a mindless rampage.

Pursuing him to the subway station, Newt attempts to comfort Credence only to engage in a battle with the treacherous dark wizard. Seraphina Picquery and aurors are reported by the attack, and they cast destructive spells at Credence leading to his presumed death.
