Red Giant
From Jenny Everywhere Wiki
In Reality Z-25 31-H, “Red Giant” was an operative of Ohmega, drawing his name from having been granted the use of one of the organisation's experimental bio-energy-based power armours, with his being a striking silver-and-scarlet colour scheme.
After the symbiote-bonded Kate Five and the newborn symbiote Balthus tore their way through the regular security forces watching over the process of Balthus's birth, a squad led by Red Giant intervened. Though wounded, Kate insisted on facing Red Giant herself, telling Nexus Girl, who'd only just arrived on the scene alongside Battle Angel, to keep back. (COMIC: Kate Five vs Symbiote - Chapter 5)
