Private First Class Ricco Frost, nicknamed “Frosty” or the “Zen Master” owing to his cool attitude, was a member of the United States Colonial Marine Corps, part of 2nd Battalion Bravo Team. He was a member of the combat unit deployed to LV-426 aboard the USS Sulaco in 2179, to investigate the sudden loss of contact with the colony of Hadley’s Hope. He subsequently perished as a result of the Xenomorph infestation at the colony.
Frost was part of Second Squad’s rifle team, along with Corporal Dietrich, and was also a skilled martial artist, holding a first-degree black belt in the Marine Corps Martial Arts Program. He was killed by friendly fire inside the Hive when Dietrich accidentally set him alight with her flamethrower.
