Ohmega
In Reality Z-25 31-H, Ohmega was an unscrupulous organisation who researched bio-energy and related advanced science and engineering. (COMIC: Kate Five vs Symbiote - Chapter 5) Its chairman was Robert Pelham. (COMIC: Kate Five vs Symbiote - Chapter 6)
History
Ohmega helped David Cameron be elected as Prime Minister of the United Kingdom, in exchange for him promising to facilitate Ohmega's operations once he was in office. (COMIC: Kate Five vs Symbiote - Chapter 6)
Kimberley Jones came to work for them, developing her own bio-engine-based E-Valkyrie suit and self-repairing nanites. After she learned that her sister Kate had bonded with a powerful alien entity known as a symbiote, she convinced Ohmega to lend their resources to diverting the imprisoned Kate from official channels of prisoner transfer to take her to their secluded on facility on Sark Island. There, she studied the symbiote, and then, as part of “Project Fenris”, arranged for it to “escape” and impregnate her with a spawnling, hoping to harvest the new symbiote from birth and use it as a living battery. However, forewarned telepathically by Kate's symbiote Ghede of the doctors' intention, the new symbiote was born fighting, and, with Kate and Ghede's help, it slaughtered large numbers of Ohmega's staff and security personnel, including the lead doctor assisting Kimberley on the project.
However, a second round of security forces soon arrived, led by Red Giant, an other bio-energetic-armour-user (COMIC: Kate Five vs Symbiote - Chapter 5) who was also a vampire. He nearly got the better of Kate, but she was saved at the last moment by Battle Angel (COMIC: Kate Five vs Symbiote - Chapter 6) who had come to the Island with fellow Section P member Nexus Girl to retrieve Kate, whether as an ally or a prisoner. (COMIC: Kate Five vs Symbiote - Chapter 5) Meanwhile, Ohmega forces had subdued the symbiote-bonded Kimberley and, deeming Balthus a more valuable resource than the fickle human scientist, prepared to forcibly extract the symbiote from her in a manner which would have killed her. Nexus Girl intervened, calling on the power of the Nexus Stone. Accepting that Ohmega had betrayed her, she agreed to team up with Section P as they made their escape. Meanwhile, however, appraised of the situation, Robert Pelham phoned David Cameron, asking him to tell Sir James Carey to stop Section P from interfering in Ohmega's affairs.

A few minutes after Kate Five's escape, the Sark Island facility was again breached by people who were looking for her: this time, New York City's Centennia and Captain Perfect. Centennia let the two of them get captured, hoping to get information, but broke her restrains with ease as soon as she heard that they'd “just missed” Kate. Centennia then got a phone call from Professor Madison, explaining that Kate and her friends had in fact teleported to New York, and were now waiting for her in the Fortress of Evening.
