Malthus, more commonly known by its vessel Annabelle the Doll, is a powerful demonic entity that, despite being able to exist independently, frequently latches onto a porcelain doll to torment those who own it. It is one of the artifacts taken by paranormal investigators Ed and Lorraine Warren during one of their cases. Annabelle is considered to be their most dangerous and haunted item and has a habit of moving around unseen. Malthus appears to be absent of any kind of mercy or remorse, often toying with its victims before attempting to kill them and take their souls. Malthus is also very sadistic, persistent, aggressive, and terrifying. It also takes pleasure to see its victims terrified or depressed, tormenting them by taking on forms of their loved ones, such as Annabelle "Bee" Mullins. It is also very violent, such as gouging out Esther's left eye and then years later, murdering her by chopping her body in half and then having the bisected upper half of her body crucified onto the wall. Just like Valak, he also acted in an disrespectful manner regarding the death of the Warrens by old age, laughing and mocking of it.
