The Three Doughmen

As Experiment 1322, the Bigger Bodies version of Doey, his personality can be divided into three, matching his components: Matthew Hallard, Kevin Barnes, and Jack Ayers.

Matthew is the most prominent mind in Doey, and he is often overly cheery and playful, displaying his characteristic charisma that made everyone in Playcare fond of him and that got him chosen for Project: Doey in the first place. In casual moments, he is teasing and friendly towards The Player, referring to them with diminutives such as "pal" and "bud". He has a tendency to refer to darker subjects, such as his killing and devouring of Pianosaurus and if The Player has killed The Doctor yet, gleefully, which can come off unnerving yet never seems ingenuine. However, during certain moments, such as when he debates Poppy Playtime about the ethics of her plan to detonate the Factory and everyone within, he becomes more serious and cautious and speaks more monotone. He is extremely compassionate, seeing humanity in all the experiments and wanting to protect the ones he leads in Safe Haven, which leads him into conflict with the more pragmatic Poppy. Though he is overall the most dominant mind in Doey, he cannot restrain Kevin when the latter becomes enraged, as seen when Kevin blames The Player for Safe Haven's destruction and Matthew tries to give a more nuanced perspective, Kevin instantly shuts him down and takes over to attack The Player. Despite his usual cheer, Matthew is deeply insecure, sourcing from an incident that got his family killed; he believes everything that goes wrong is his fault and berates himself for it, often attributing it to him neither being good enough nor intelligent enough. His behavior possibly stems from his lack of intellect and strength prior to the procedure, and with Doey being very physically imposing, he is left feeling his sole purpose was "only made to hurt things". He is also afraid of The Prototype, as he freaks out when Poppy reveals he's near Safe Haven when she, The Player, and Kissy Missy arrive, and later is very hesitant to even lead 1006 away when Ollie informs them he's nearby.

Kevin is the second-most prominent mind in Doey, though he still takes over far less than Matthew. He suffers from severe anger issues, seemingly sourcing from however his parents were, considering his reaction to Jack's parents and listing his own among those he needs to "hurt back", which Playtime Co. seemingly never attempted to treat and just let him stew in, leading him to respond to stressful situations, which is when he typically emerges, by finding someone to blame for the situation, screaming extensively, forcing the other two minds into submission, and, of course, attacking who he chooses to be responsible, as seen by his breakdown after Safe Haven's destruction. Notably, he does seem somewhat compassionate, as he is angry at Poppy for abandoning her supporters in the past and snaps when Safe Haven is destroyed. He may also be insecure, as when Matthew starts to berate himself near the end, Kevin seemingly tries to join in, only to be interrupted by the killing blow. He may also surface during rare moments of reflecting on the past, particularly Playtime Co.'s cruelty, without rage, using a dry voice, but it's difficult to distinguish this from Matthew's serious moments.

Jack is the least prominent mind in Doey by a vast margin, only surfacing a few times in Chapter 4, notably near the end in response to extreme distress. He speaks rather immaturely and often playfully. He expresses grief over Safe Haven's destruction like the other two, but attributes blame to the direct culprit, The Prototype, without focus rather than raging at the indirect in The Player and Poppy, unlike Kevin. He laments being trapped in the Factory, calling out for his "Mommy" and "Daddy", who Kevin killed previously in a fit of defensive rage. It's clear he also regrets Kevin's violence, as when Doey is dying, he tearfully apologizes first, proceeding Matthew's own apology.
