From CoH Comic Index
Kirk Cage is the owner of Cage Consortium, one of the dominant construction companies in the Rogue Isles.
A ruthless American businessman, Cage arranged the purchase of Sharkhead Isle so he could have the mineral rights to mine the strange substance known as bauxite. As the owner of the isle, he was given a governorship by Lord Recluse and has free reign to run the area as he wishes.
But even though he almost literally owns a whole island, Cage still yearns to dominate the construction business in the United States, and especially in Paragon City. To that end, he retains contact with local businsses through his connection to the clandestine group otherwise known as Shadowborn. City leaders refuse to work with Cage, citing his control over Sharkhead Isle and his connection to Lord Recluse, which is a violation in and of itself of several U.S. laws.
(See his Paragon Wiki entry for more information.)
Although mentioned, Kirk Cage is currently never seen in-game.
