"!" *For Huggy Wuggy, his general premise is to hug children, with his name being a play on the word 'Hug'. Going on the same logic, Kissy Missy's purpose would be to kiss children, hence it can be safely assumed that her toy form's personality is loving and kind.

According to the Digital Collectible Campaign, she is a stickler for rules and does not hold back on reprimanding those who go against said policies.

Unlike the other toys, who are very hostile, she appears to be benevolent, sweet, and helpful towards The Player, even going so far as to assisting them in opening the gate door via the lever on the other side rather than killing them. In Chapter 3, she assisted them once more alongside Poppy Playtime, serving as the latter's form of transportation in order to stop the Prototype and end this once and for all.

However, during the Hour of Joy Tape, she killed the train workers (with her arms alone) who were escorting her to Playcare, showing a much more ruthless, merciless and stronger side akin to Huggy Wuggy. It's worth noting that she returned to her original position soon afterwards, implying she didn't fully participate in the rebellion; given that she is rarely aggressive, it is possible this was done in the spur of the moment due to anxiety, which Kissy regrets doing. Kissy also harbors bitter memories of Playcare, appearing again while exiting out of Home Sweet Home and tackling The Player, though sparing their life under the request of Poppy Playtime as she had mistaken them for a threat.*
