Aeon Corporation or "Aeon Corp" is one of the biggest companies in the Rogue Isles in the City of Heroes MMO. It is founded, owned, and operated by Doctor Thaddeus Aeon, a man who holds several unique distinctions in the Isles. He serves as one of the "elite" members of Arachnos, but he is also a key member of the Rogue Isles Infrastructure and a founding partner of Architect Entertainment and an advisor in the United Nations global security division Vanguard.
Aeon Corp is the leading technological company in the Isles, providing endless power for the Isles through the Power Transfer System. They also invented both NutriPaste and the experimental hydroponic farms to grow food for the Isles.
(See its Paragon Wiki entry for more information.)
Aeon Corp was seen in the one-shot "Naughty Nadya".
