Lieutenant Gomez is a commissioned officer of the UNSC Navy who serves aboard the UNSC Infinity.
In March 2558, Gomez was present onboard Infinity during Fleet Admiral Terrence Hood's diplomatic mission to Ealen IV. During the peace talks, Infinity lost communication from the surface. Unbeknownst to them, the delegation had come under attack by Covenant mercenaries. Gomez had suggested deploying Orbital Drop Shock Troopers down to the planet, though Commander Bradley refused to send a battalion to the diplomatic meeting, as he believed the loss of radio contact did not indicate hostilities.
