Frizzletop was an army nurse who lost an arm during a Japanese air raid in the Philippines and was called Frizzletop because of her frizzy hair. She was engaged to marry Tiger Lily’s brother, John who had also been stationed in the Philippines. Sadly, John was killed in the same air raid that cost her an arm and she returned to the States to tell Tiger that his brother was dead.
She tracked Tiger to Wood City, which he had recently vacated. In Tiger’s abandoned apartment, she met Dick Tracy who was investigating Tiger’s involvement in a certain train wreck and the murder of Mr. Amard. She told Tracy a bit about her background, then left to continue her search for Tiger, whom she found in the nearby town of Haver. Tiger maintained a secret hideout and took a liking to Frizzletop and hired her to work in his clubhouse.
Frizzletop soon discovered evidence of Tiger’s criminal activities and began to fear for her safety. She attempted to flee on a boat, but collided with Dick Tracy and Junior, who were using a raft to try to observe Tiger Lilly’s actions. Tracy and Junior had been living at the golf club, posing as a new grounds tender and caddy, respectively. When Tiger discovered Frizzletop was conspiring with the cops he set a death trap for Dick, Junior and his brothers fiance using a holed boat on the river.
Junior and Frizzletop managed to plug the hole long enough to be rescued by a passing police officer, Dennis O’Copper. They then returned to Tiger Rest and rescued Tracy. Tracy and O’Copper resolved to track down Tiger Lilly and bring him to justice. They instructed Frizzletop and Junior to stay at a nearby hotel.
After attempting to hide out at a local hunting cabin, Tiger and two of his men had left a local game warden for dead and were trying to escape on a raft. The raft was pulled into a new water intake channel, and the three men were stranded. The channel was located very close to the hotel where Junior and Frizzletop were staying. One of Lilly’s men tried to swim to shore and was believed drowned. Junior and Frizzletop heard the commotion and called in the local constable to help pull the men to safety. After Tiger and his associate were arrested and in custody, Frizzletop returned to the city with Tracy and Junior in Dennis’ borrowed car.
On the trip back, the trio was in an accident and took refuge for the night in a nearby barn. There, they discovered the body of George “Cal” Bullett . This led them to investigate the poison gas manufacturing scheme set up by Bullet’s son Cal Bullet Jr. Cal was passing messages to the mysterious “Boche” (later revealed to be Pruneface) by way of a request juke box operated by Clara. Tracy used Frizzletop’s skill at mimicking voices and had her impersonate Clara to get information on who Cal was working with, though Frizzletop had no further involvement with the Pruneface investigation.
Later, Frizzletop announced her intention to go back to Texas and help her father operate his ranch. However, she was soon offered a job as a nurse at a day-care facility for the children of war workers, which was operated by the wealthy philanthropist Mrs. Potter. One of the children, Johnny Wreath, was kidnapped by his father Nifty. Frizzletop notified Tracy, which started the search for the child. She later consoled Johnny’s mother, Myrtle, and was present when the family was re-united.
Frizzletop re-appeared in 2012, having married Dennis O’Copper in the time since she was last seen. It has not been established if she took Dennis’ last name. She revealed to Chief Patton that she was a cousin of the notorious criminal Flattop Jones Sr., and that Flattop’s estranged wife Stiletta (aka Mrs. Flattop) was seeking revenge on Dick Tracy.
