Molly Hayes

Molly Hayes (also briefly known as Princess Powerful or Bruiser) is a fictional character in the Marvel Comics award-winning series Runaways. She was created by author Brian K. Vaughan & artist Adrian Alphona, and debuted in Runaways #1 (April 2003) with most of the other main characters. Like every member of the original Runaways, she is the daughter of evil villains with special abilities; after the other older Runaways learn more about themselves, they raid Molly's home to find out her mutant abilities had already manifested. Often called "Mol" for short, Molly is the youngest Runaway and her innocence often serves as humor in the series, but she has demonstrated great insight at critical moments.

Molly was originally the team's sole mutant; despite having telepathic mutant parents, Molly's mutant powers are superhuman strength and invulnerability. She used to be the youngest member of the team, but after inviting fellow mutant Klara Prast to join, Molly takes comfort in having another mutant and someone her own age. She is extremely proud of her mutant heritage and admires the X-Men. Runaways creator Brian K. Vaughan played a significant role in the character's subsequent development as well as artist/writer Adrian Alphona. Molly was named after Runaways creator Brian K. Vaughan's younger sister, Molly Hayes Vaughan. Her trademark is an expansive lineup of hats displayed throughout the series. In 2009, Molly was named the fourth (out of ten) toughest females in the Marvel Universe, after Rogue, She-Hulk and Ms. Marvel.
