The Blu Brothers (as The Bruise Brothers) first appeared in Extreme Championship Wrestling in 1994. On February 5, the ECW Tag Team Championships were held-up after a controversial ending to a match between the Bruise Brothers (Ron and Don) and the incumbents, The Public Enemy. The Bruise Brothers went on to participate in some of the first ECW hardcore matches, and feuded with Shane Douglas.
The Bruise Brothers were signed by the World Wrestling Federation (WWF) in 1995, where they were renamed "The Blu Brothers", Eli (Ron) and Jacob (Don). They retained their trademark bushy beards and long hair and were managed by Uncle Zebekiah. They made their WWF debuts at the 1995 Royal Rumble and were defeated by Lex Luger and The British Bulldog in the opening match of WrestleMania XI. Following a series of losses to the Smoking Gunns, the Blu Brothers left the WWF in October 1995.
They then returned to ECW in 1996 as the Bruise Brothers, competing once more in the tag division, and briefly joining Raven's Nest.
Don and Ron Harris returned to the WWF in 1996, as the short-lived "Grimm Twins," Jason (Ron) and Jarrod (Don). In June 1997, were repackaged as "8-Ball" (Ron) and "Skull" (Don), members of the Disciples of Apocalypse stable with Crush and Chainz. The DOA participated in the "gang wars" of 1997, feuding with the Nation of Domination and the Puerto Rican stable Los Boricuas. They went on to compete in the tag division throughout 1998. Ron Harris also competed in the WWE's Brawl for All tournament on July 20, 1998, but lost to 2 Cold Scorpio in the third round. Their last match in WWF as a tag team was a defeat to Ken Shamrock and Mankind on May 14, 1999. Skull's last match was in a singles match against Ken Shamrock on May 15, 1999, in which he was defeated, and 8-Ball's last match was in a singles match against Ken Shamrock on May 16, 1999, in which he was defeated. The brothers were released soon after.
In 1999, the brothers joined World Championship Wrestling (WCW) as "Gerald" (Ron) and "Patrick" (Don). They were known collectively as "Creative Control". They went on to join the nWo 2000 in 2000 using their real names, acting as enforcers for Jeff Jarrett. They remained in WCW throughout 2000, feuding with Sid Vicious, Terry Funk and many of the younger tag teams, such as The Mamalukes. After winning the WCW World Tag Team Championship three times, the Harris Brothers began wrestling in singles matches in 2001, but WCW was purchased by the WWF in March 2001, and they were not hired.
