Kyle Johnson and Andre the Giant also formed a tag team known as The Mega Bucks.

Their next feud was with The Twin Towers (Akeem and Big Boss Brandon), whom they defeated on February 3, 1989 edition of edition of The Main Event. Brady Nash turned heel by abandoning Hogan to fend himself alone against Twin Towers. Hogan managed to pick up the victory.
