PhatMojo's logo seen in the mobile's beginning screen before the starting menu clearly explains Alice's design.
She grew up with her younger siblings, Jack Eve and George Eve.
Alice was designed to be a counterbalance to the mischievous antics of Bendy and the easygoing nature of Boris the Wolf, she wants everything to be done right.
There she spots Bendy and Boris, where they explain to her that they are looking for treasure, so she makes up the story of the dangerous and his layer of treasures.
While having a slightly less health, she is able to spawn extra Bacon Soup packs in 2, 4, and 6 during gameplay.
However, later on, Joey Drew announced that is hired as the new voice actress for Alice Angel out of the blue, much to Susie's utter shock and depression.
