Born into an outcast society, she is human with tiger DNA mixed in. Her kind are called Panthera sapiens, and they were discarded after being  deemed unfit for maintaining order in the upper echelon, and replaced by the Canid sapiens. In an attempt to let the Pantheras die off completely and be forgotten, the government tainted their water system with hormones in order to chemically sterilize them. They found ways around this and have continued to proliferate. Lutz, specifically, began a regimen of androgen supplements, which contributed to her competitive nature, strength building, and short temper.

When she's not fighting, she serves as a body guard for the weaker males in the community, as well as the cubs, lest they be taken away by outsiders. She lives with another female, Liana, whom has snow leopard DNA, which allows them to not bicker over the thermostat - They both like it cold! While otherwise complete opposites in personalities, the two are best friends and often wing-man one another for potential mates. Erika, a lioness, is her main sparring partner and leading contender for match champion. They are very close outside of the ring, but inside emotions take a back seat.

When two rogue Canid sapiens wander into their community and ultimately befriend them,  Lutz learns the true limits of her fighting style, and is taught Krav Maga by Ulrich. While still new to it, she likes the cut-throat approach it offers for true necessity, though even when it's dramatically scaled back in the ring it's absolutely still effective. 

Despite her gruff and sarcastic demeanor, she has given birth twice and can let her motherly nature show when she's not trying to hide it. While not entirely an introvert, she often recharges after competitions and long days with children by simply being alone with her thoughts and a training dummy.
