History
By 2011, a Helicron, a matter gun, and a skull crusher was stored in the Vault, the original site located under the Cheviot Hills. According to director Vanessa Hardcastle, the matter gun had accidentally disintegrated two humans, Patricia and Zufran; as Vanessa believed that as the duo had no families, and that the "relevant procedures" had been carried out, the deaths weren't worth reporting. This prompted Patsy, from P.R.O.B.E., to send Giles and Archie to investigate the site. Vanessa later told Giles and Archie about the deaths.

After the Cyberon fluid escaped its container due to it being improperly stored, the Cyberon went to the cold storage, considering various hosts within, including a Helicron, but the Cyberon decided against the Helicron, chosing a young, deceased werewolf instead. After the Cyberwolf hybrid rampaged around the site, many items in one of the warehouses were knocked to the ground, including the Helicron skull crusher. (PROSE: A Worthy Successor)
