Main Event Mafia 2013: Possibly the most pointless 'Re-union' of a group ever. The idea of the reform was to fight Aces and Eights. The results were Rampage promoting his next fight, Kurt Angle goes to rehab, Magnus feuds with Sting after only a few months or less leading to a Magnus heel turn. Terrible idea, Ken Anderson ended up finishing the Aces and Eights.
Judas Mesias in TNA: From first glance Judas Mesias coming to TNA was exciting, he had Abyss' former manager James Mitchell at his side and the guy looks fucking scary. After the Abyss rivalry TNA really had nothing creatively for him so he was released from his contract. Although the gimmick has been successful in other promotions it just did not work out for TNA.
Hulk Hogan in TNA: When Hogan joined TNA I was a little surprised and excited that he could change them for the better, I was wrong. The idea of Hogan being in TNA is great, I mean Hogan is an American wrestling legend and hall of famer right? So naturally he would bring a constant line of fans to TNA right? Nope. The storylines just sucked, they brought in Brooke Hogan to be a part of those storylines too :aries:. It's best that TNA fans forget Hogan's time in their company.
These are the first three things on the top of my head in TNA that hypothetically sounded good for business but turned out poor.
