(Covers information from Anderson's universe)
Specimen 87 was engineered as part of Dr. Isaacs' attempt to treat the millions infected with the T-virus, having theorised that Alice was a perfect test subject for developing new treatments. Without access to Alice, he resorted to creating a number of clones to replicate her. As a side-project, he intended for each clone to become a potential replacement to her, thus forcing #87 to go through a laser grid and booby trapped corridors to test her reflexes. Eventually she was killed in a recreation of the Raccoon City Hospital by a Super Undead.
