The Valentine Brothers

Jan and Luke

Luke and Jan Valentine are a pair of vampire brothers who work for Millennium, having apparently worked as hit-men or have a long history in criminal activity while being presumably Americans. In the anime, the brothers were night club owners before their conversion.

While the volatile and rude Jan Valentine (ヤン・バレンタイン Yan Varentain) is a run of the mill vampire armed with a pair of heavily modified, suppressed FN P90s, the calm and reserved Luke Valentine (ルーク・ヴァレンタイン Rūku Varentain) is specially modified to have accelerated healing and speed with the use of a pair of sawed-off M1 Garand rifles, a curved bowie knife, and a Walther PPK concealed up his sleeve. With an army of ghouls in militant garb, the brothers stormed Hellsing HQ.

While Jan faced off against Walter and Seras, incinerated by Millennium upon failure and using his final moments to reveal the group's name, Luke descended into the basement to kill Alucard for the sake of infamy as believed he was superior to his opponent. But when Alucard removes his restriction seal over who he thought to be a worthy opponent, Luke is revealed to be unable to regenerate loss limbs and is devoured by Alucard's Baskerville familiar.

In Hellsing IX, during Alucard's fight with Walter, Luke emerges briefly from Alucard's Baskerville familiar which was sliced in half. He is subsequently used by Walter as a puppet to fight Alucard. However, Alucard used his powers to turn Luke into a decoy to catch Walter off guard.[6] The Valentine Brothers also appear in the omakes in the manga after their debut, making light of their deaths. Their prototypes were in The Legends of a Vampire Hunter.
