At 7 feet tall and nearly 400 pounds (2.1 meters and 29 stones where she's from), Lily Fenn is a fiendish enforcer and courier for a grey and black market dealers.

From a young age, Lily displayed a cruel and sadistic nature. One of these unique habits was to attempt to alter her grimer-body with as many toxic chemical she could get a gooey on, making her a terror when it came to inflicting poisonous attacks on others in schoolyard brawls.

When evolving into a Muk, it was discovered her body's naturally forming toxins, combined with the unnatural ones she has injected herself with over the years, were far more potent than usual. This combined with her less-than-pleasant odor necessitated the use of a full body suit that sealed her poisonous body away from the rest of the world. She enters it from a port in the back, and rarely is seen eating in public, as food has to be put through that same port as well (having an amorphous body helps to move her mouth anywhere in her body). Rumor has it that her suits have secret ports that allow her to spew toxic slime, though she has yet to be confirmed using these.

If you ever wanted to feel what a waterbed filled with oobleck felt like, just give her love handles a pat and a squeeze. The punch after that would also provide a good example of her strength.

Her closest enemy and rival in the illegitimate delivery industries, a scrawny Rattata lady named Lavender, always takes a chance to call her "Minging" when they meet on business. Someday, Lily will show that mangey masked rodent the true power of her toxins.
