Worst: Squirrel Girl
Yes, Squirrel Girl is a superhero that actually does exist. She is a mutant with no squirrel biting story, unfortunately. She has many powers similar to squirrels which are as weird as you think. She has superhuman strength and agility, which allows her to leap several stories, as well as an enhanced sense of smell. She also has 2 – 3 inch retractable knuckle spikes that can slice wood, in addition to sharp claws on each digit that can be used for climbing. She can also communicate with squirrels. What does she use these powers for? Thankfully, beating up Deadpool.
