|Unknown (presumably 2012)|
The first known deployment of the Ogroman was on Christmas Eve, 2012, when the Edonian Liberation Army was losing its fight with the newly arrived Bioterror Security Assessment Alliance. Despite Carla Radames' warnings of a flaw in the Ogroman's design, the ELA's commanding officer had no time to wait for the correction to be made and sent it out against the BSAA. Encountering the North American Alpha Team, it was fought off by the combined efforts of Chris Redfield and Piers Nivans. Later when Chris and Piers encounter Jake and government agent Sherry Birkin, the four of them fought another Ogroman transported by the ELA J'avo, whilst destroying three anti-aircraft guns. After destroying two of the guns, the Ogroman that was driven off earlier reappears. After killing one of the B.O.W.s and disabling all the guns, the second beast is killed by an airstrike.
Another Ogroman was later encountered by Chris and Piers on the deck of Neo Umbrella's aircraft carrier. It was released to prevent them disabling the missiles aimed at Lanshiang but Chris managed to distract it long enough for Piers to deactivate the missiles. This Ogroman was presumably killed when the aircraft carrier was destroyed.
The creature is an approximately 30 feet tall humanoid, albeit one with disproportionately long arms, and an overdeveloped bone structure; seen in its legs, hips, and jaw. In at least one instance, there is a large, rod-like device that connects to its internal organs and protrudes slightly from its back.
The Ogroman possesses impressive strength, capable of picking up humans, buses, and other heavy object, as well as damaging buildings and destroying gun turrets by punching them. It used its weight to its advantage, employing a wide range of crushing attacks, from stomping, smashing, or accidentally falling on its targets. Its bone structure also made it nigh-invulnerable, with even artillery having little effect on its protected areas. Despite this, the Ogroman has two visible weak points; the first being its raw and gaping mouth, and the second, if applicable, the internal organs exposed by pulling the rod-like device on its back. Damage to either will stagger the Ogroman, forcing it to its knees.
The creature is presumably of human origin, but whether it is the result of multiple fused humans or is created in a similar manner to the El Gigante is currently unknown.
When the Ogroman is killed, it will disintegrate into indistinguishable biomass, similar to other B.O.W.s of its origin. If the player gets too close, they will pull up their arm over their face, apparently from disgust, and their health will deplete while doing so.
