A Siberian demon tiger is quite like a standard Siberian tiger, in that their base coat is a brilliant white. However, their stripe's and even genitalia's color change based on their mood. As they grow older they learn to better control this, but they are still subject to color changes when they have extreme emotions. Color is not all that is affected however. Each affected area is covered in small glands, which secrete various flavors that match the tiger's color. When ingested these secretions deliver powerful feelings of euphoria, and in several cases have even been reported to have hypnotic/hallucinatory properties. They use this powerful combination of colors and flavors to draw in unwitting prey, often seducing them first, before claiming their meal.
When they eat demon tigers rarely kill their victims, often choosing instead to take non-vital parts while the prey is trapped in a state of euphoria. In fact, a large number of their victims are often grateful for the experience, and many choose to begin lives of service under the demon who afflicted them. Fortunately Demon tigers do not need to eat very often, and can go for weeks at a time on a pound or two of meat.
It is worthy of note that during times of extreme happiness, the stripes of a demon tiger will take on a rainbow pattern. While in this state the secreted flavor takes on a very different chemistry, losing it's hallucinogenic property, and instead assuming the flavor of the testers most cherished foods. This state is easiest to observe when with someone they love deeply.
Krechevskoy in particular has inherited a precious family heirloom. He wears a crimson scarf which he inherited from his grandfather, a former royalty. The scarf is a powerful artifact which was used during the fallen empire's reign to signify kings. It is given to a demon child at birth and grows with them, almost like an extra limb. It can move and shrink and grow on command, limited only by the will of the user. The cloth is strong, and even when torn, it can quickly regenerate, making it very useful both as a shield and a weapon. It can be removed, but he is almost always seen wearing it.
