Lily is a large Gamma-irradiated French poodle, Lily is the second largest and only female of the trio of beasts. Despite her breed, she possess a strong, muscular build. Unlike her two male counterparts, she has less green on her body and is the least mutated in appearance. Lily still has glowing green eyes and her tongue and jowls are green. She seems to be the most obedient of the three as she is totally focused on getting to Betty Ross rather than Hulk. Before her exposure to Gamma radiation, it is hinted that she is one of David's favorite as she is seen sitting by his side when he enters Bruce's lab. In something of foreshadowing their Gamma-irradiated battle, Bruce encounters Lily sitting in the hallway of his lab. When he approached her, she gnashed her teeth at him as a warning not to touch her without permission. She appeared to be more reserved in comparison to Smokey and Sammy, sitting by David's side while the former two run amok and play. During the battle she still does attack Hulk at certain times while most of his damage comes from the two male beasts. She has the least damaging bites albeit when she bit and latched onto Hulk's groin. This resulted in him smacking the dog off hard with Lily flipping before hitting the ground. She is the most threatening to Ross whom is the intended target by David. Interestingly, this suggests that Lily is the most intelligent of the group but no less savage. Like the other two dogs, Lily eventually meets her match at the hands of Hulk as the others do. As she is attacking Ross's SUV, Hulk who had just killed Smokey, jumps high above and lands squarely onto Lily, snapping her spine. Lily's head is thrown through the windshield by the impact and is inches from Ross's face. As Ross looks into Lily's face, the dog's body begins to melt right before Hulk then aggressively grabs Lily's corpse and throws it away from Ross, where it explodes in a glowing burst of green mist midair. Seemingly the damage inflicted upon Lily had caused the Gamma radiation in her to go into meltdown, resulting in her remains melting then exploding.
