A bottle of Coldkiller X.

While they were both studying at Ivy University, Dahlia Hawthorne attempted to kill Phoenix Wright with his own bottle of Coldkiller X by mixing in some poison she had stolen from the pharmaceutical department. Her reason for doing so was in order to regain her bottle necklace, which was evidence from her poisoning of Diego Armando.

Coldkiller X was also present in the Zodiac Art Gallery's infirmary.
