Drexel Power Plant.

First Appearance: "Russian Roulette."

Details: Russian bounty hunters Sonya Barovsky and Yuri Pogrebin made their hideout in the old Drexel Power Plant while fixing their mutant detecting device, the Puska H5B7. After Mutant X had deactivated the Pushka and notified the Immigration and Naturalization Service of the pair's operations, Brennan Mulwray destroyed these headquarters.
