The Wulfeck males are such alpha-males that when they are standing too close to a beta-male, the beta-male will find himself starting to feel ill with almost flu like symptoms.
This is because the Wulfeck aura is attacking the energy field of the beta-male trying to take his life.
Even when a Wulfeck seems innocent, he is not, and is always trying to destroy his enemies.
Oh, shit Noah, do you have the Wulfeck Flu?
