Hulk Hogan and Brutus Beefcake began their careers more or less at the same time, quickly becoming lifelong friends and would team up from time to time. Their most well known “Pre-WWF” teams were as “Terry & Ed Boulder” and as “Hulk & Dizzy Hogan”, billed as brothers.
During the summer of 1989, Hulk Hogan came under attack from “The Human Wrecking Machine” Zeus, an actor who had starred as Hulk's enemy in the WWF financed film No Holds Barred. Zeus teamed up with “Macho Man” Randy Savage in hopes of destroying Hulk Hogan. Faced with overwhelming odds, Hulk Hogan turned to his best friend Brutus Beefcake to even the odds.
At SummerSlam 1989, Hulk Hogan and Brutus Beefcake teamed up to take on Randy Savage and Zeus in the main event, a clash that saw Hulk Hogan pin Zeus after his trademark Leg drop. Hogan and Beefcake would once again team up after being attacked in the locker rooms during the closing moments of the 1989 Survivor Series PPV by Savage & Zeus.
It was decided that the feud had to be settled in a steel cage match, which was featured on a “Mini-PPV” as a double feature with the movie “No Holds Barred”. Hulk Hogan and Brutus Beefcake were successful in the cage, after which Zeus was not seen in the WWF. After the steel cage match, Hulk Hogan and Brutus Beefcake both went back to working singles matches.
In 1990 Brutus Beefcake suffered a devastating face injury during a parasailing accident that forced him to retire from in-ring competition. After an aborted comeback attempt in late 1991/early 1992, Brutus Beefcake finally felt he was ready to get back inside the squared circle in 1993.
On February 1, 1993 (shown on Television February 15), Brutus Beefcake faced off against “The Million $ Man” Ted DiBiase with his Money Incorporated partner Irwin R. Schyster and manager Jimmy Hart at ringside. IRS would interfere in the match with Money, Inc. double teaming Beefcake, even going so far as to hitting him in his surgically reconstructed face with a metal briefcase. The actions of Money, Inc. were so horrible that life time heel (bad guy) Jimmy Hart took objection to it and tried to protect Beefcake from further harm.
At this point in time, Hulk Hogan was not active in the WWF, having gone into semi-retirement a year earlier, but the attack on his lifelong friend brought the Hulkster back to the WWF. With newly turned babyface manager Jimmy Hart at their side, Hulk Hogan and Brutus Beefcake joined forces, swore vengeance on Money, Inc. and then officially named themselves “The Mega-Maniacs.”
Due to the attack by Money, Inc, Beefcake took to wearing a red and yellow protective facemask when competing in the ring and Brutus's entire outfit changed to red and yellow as a show of unity with Hulk Hogan.
Leading up to WrestleMania IX, the Mega-Maniacs took on the Beverly Brothers during house shows to get ready for their shot at the WWF World Tag-Team titles at WrestleMania. The Mega-Maniacs were not successful in their challenge as they lost to Money, Inc. when Hulk Hogan used Beefcake's steel face plate on the champions. Later in the night, Hogan would win the WWF World Title in an impromptu match.
The Mega-Maniacs would team up and take on Money, Inc. several times during the months of April and May on the house show circuit with the World Champion not defending his title once. Hogan would lose the title to Yokozuna at June's King of the Ring pay-per-view, and both he and Beefcake would leave the WWF soon after.
When Hulk Hogan signed with World Championship Wrestling in 1994, Hogan's friend Brutus Beefcake was not far behind, being known as “Brother Bruti” in WCW. Despite appearing together many times over the years in WCW, they only teamed actively in the ring for a very short while when Brutus Beefcake was known as “The Booty Man” during the early parts of 1996, but they could not use the name “The Mega-Maniacs” due to the WWF owning the copyright.
