After graduating from Ohio State University, she landed a job at a small tech firm in Northern California, but also took an interest in competitive fitness. Soon, she was spending all of her weekends flying to different cities to compete in fitness competitions, bodybuilding competitions, triathlons, Tough Mudders, Crossfit Games and more. She began making so much money from winning these competitions that she was actually able to quit her day job.

Things, however, began to get out of hand when Lilly got hooked on synthetic steroids. At first, the effects of the drugs were pretty normal – she was getting stronger, faster, more muscular and more agile. But she continued to chase more powerful mixes, which eventually led her to discover a super-substance that had been created and developed through a cryogenic process.

Through a few friends in the fitness community, she was able to gain access to the “Hyper-Cryo.” But when she injected herself, something went terribly wrong. Her body had an immediate and extreme reaction, as her muscles began to grow at a ridiculously rapid rate. But that wasn’t all – suddenly, the molecules in her body began to accelerate at such a high speed that her body actually evaporated and became a snowy mist!

Incredibly enough, however, she wasn’t dead. In fact, she could still think and move in mist form. After the initial shock of it all, she discovered it was quite extraordinary. Eventually she figured out how to reconstitute her physical body, which was now even more ripped and muscular, and quickly learned she had gained extreme hyper-strength.

The combination of her immense strength, along with the ability to take the form of cold mist at will, made her a very powerful individual. She also had the ability to fly, and found that she could now breath in outer space. So she decided to become an intergalactic superhero, and after a few months of battling super villains from both Earth and beyond, she was noticed by the mighty Magnifica, who asked her to join the Diamond Alliance.

Thundersnow jumped at the opportunity, and became the team’s strongest member (at least in terms of sheer strength). She also continued to evolve her computer skills, and often acted as the team’s tech advisor. But really, she preferred to be the enforcer, and her brutal strength and brash attitude came in handy when the team was attacked by Eridanus, a member of the savage warrior collective called the Denizen Supreme.

Eridanus had tracked down the Diamond Alliance to a moon in the far reaches of the Andromeda galaxy. His mission was to find King Ka’Desh, the former ruler and last survivor of the now-destroyed world Mederia. The Denizen Supreme was the group responsible for the destruction of the planet, and now Eridanus was there to make sure its people were extinct as well. Ka’Desh, along with Magnifica and Utopia, tried to fight him off, but he was entirely too powerful.

Fortunately, Thundersnow and the other members of the Diamond Alliance arrived! Thundersnow was the only one who could match the brute strength of the winged warrior, and the two of them clashed in a world-shattering battle. Despite nearly losing her life in several instances, she was able to gain the upper hand and lure Eradinus into the moon’s mountainous region, where her and the other members of the Diamond Alliance were able to trap him beneath several thousand metric tons of rock and stone. It was clear that he wasn’t dead, but at the very least it would take a long time for him to dig himself out.

Thundersnow continued to valiantly serve as the Diamond Alliance’s powerhouse until the team’s final battle.
