(Capcom's primary storyline)
Dorothy (code: D-004) was a girl who was genetically engineered by The Connections as a prototype of their D-Type bioweapon series, which involved infecting her embryo with Mold and rapidly-aging her to reach the appearance of a ten year old girl to suit her function for infiltration.
Dorothy was killed by her creators, who were disappointed in her poor mind control skills.
Dorothy is only mentioned in a file that can only be accessed through datamining.
