The older of the Valentine brothers, Luke is the contrast to the younger Jan, sporting a high-class image and calm, composed demeanor. Much like his brother, he does not express any high class vampiric abilities and instead, uses a pair of sawed-off M1 Garand rifles as well as knives in combat. Luke ultimately challenges Alucard during the siege of the Hellsing Headquarters but grossly underestimates him and ends up devoured by Alucard's Hellhound.
