Daniel Eugene Spivey (born October 14, 1952) is an American retired professional wrestler best known under the ring names "Dangerous" Dan Spivey, Dangerous Dan, The Left Hand Man, Danny Spivey, Mr. America, and Waylon Mercy, initially working under the name Starship Eagle. Throughout his career, he has worked extensively for World Championship Wrestling, the World Wrestling Federation, and All Japan Pro Wrestling. He retired from wrestling in 1995 due to injuries and now works in alcoholism counseling in his native Florida.

Spivey spent a lot of his career as part of various tag teams and is especially known in the U.S. for teaming with Sid Vicious and then with "Mean" Mark Callous as "The Skyscrapers" in WCW and teaming with Mike Rotunda to form The U.S. Express in the WWF. He started his career teaming with Starship Coyote, collectively known as "American Starship". In Japan he teamed with various wrestlers over the years winning the World Tag Team Championship with Stan Hansen and teaming with Johnny Ace for long periods of time.

His last wrestling persona, Waylon Mercy, was inspired by Robert De Niro's portrayal of Max Cady in the 1991 remake of Cape Fear. While he only worked a few matches under that name, he later inspired the creation of the Bray Wyatt character as Spivey worked with Windham Rotunda to initially develop it.

Spivey was born in Tampa, Florida. He attended the University of Georgia, where he played football for the Georgia Bulldogs for three seasons as a defensive end and was named an All-American football player in his sophomore year. Spivey aimed to play football professionally and was drafted by the New York Jets but did not sign with the Jets, instead deciding to sign with the Jacksonville Express of the World Football League in June 1975. He was released by the Express in late July 1975, before the start of the regular season. Spivey spent several years working in a number of jobs in Tampa before meeting professional wrestler Dusty Rhodes, who offered to train him to wrestle.

Spivey was trained as a wrestler by Dusty Rhodes, the then-booker for Championship Wrestling from Florida (CWF) and made his debut in 1983. Spivey and Scott Hall formed a tag team in CWF called "American Starship". Spivey adopted the ring name "Eagle" and Hall the ring name "Coyote". The men wore furry boots, bright masks and silver pants.

In 1984, Rhodes moved from Championship Wrestling from Florida to the Charlotte, North Carolina–based Jim Crockett Promotions, bringing Spivey and Hall with him. Initially, American Starship worked only sporadically. At first, they were booked so sparingly that the two were given a job for the Charlotte Orioles (which Jim Crockett owned at the time) as part of the ground crew. When the two men did get into the ring it was with little success. The highlight of their stay in Jim Crockett Promotions was being defeated by Arn Anderson and Ole Anderson when the rookies challenged for the NWA National Tag Team Championship.

In March 1985, American Starship joined Bob Geigel's Central States Wrestling promotion based in Kansas City, Missouri. The duo had a shot at the NWA Central States Tag Team Champions Marty Jannetty and "Bulldog" Bob Brown but did not manage to win the titles. Spivey's stay in the Central States territory was short-lived; according to Scott Hall, Spivey did not like Kansas City.

In June 1985, Spivey returned to Jim Crockett Promotions where he worked as "American Starship Eagle". He wrestled there until October 1985.
