The Bunker is an underground base underneath M.I.9 HQ. This was where Frank London, Stella Knight directed the war with KORPS.
- The Bunker's equipment is out of date and Tom Tupper jokingly asks "Did a caveman sit here?"
- The walls are made of titanium which allowed Dan Morgan to turn the wall into an electromagnet in "Trojan KORPS".
- During the secret world war with KORPS there were 150 agents working in the bunker and 200 similar facilities around the world.
- The bunker is a restricted high-security area.
