Yngwie (イングヴェイ, Inguvu~ei) is one of the Tycoon Brothers and acts as bodyguards during the Calamity Auction. He and his brother make their first appearance in Blood Blockade Battlefront: Back 2 Back Chapter 15.
Unlike other Blood Breeds, the Tycoon Brothers act as a security team protecting whatever their clients need. The two act very professional, not showing much emotion while on the job. However Yngwie can be often spotted carrying their pet dog. The siblings are well known throughout Hellsalem's Lot as “the strongest and most feared security tag team” and “known to always act together”. The dynamic duo have certainly earned their reputation as according to Marcus Law “no one who has ever fought them has survived”.
Yngwie can summon blood spikes that penetrate his opponent’s body. Like other Blood Breeds, he can summon a cloaked figure that acts as a portal. He is also shown to be able to catch bullets in midair as well as catching a sword with two fingers. As far as regeneration Yngwie is shown to be able to survive being cut in half.
