7. Unholy Alliance, - Undertaker and Big Show, 1999
The Undertaker and Big Show tag team was short-lived, but very interesting. The partnership was formed on distrust, as Taker explicitly told Big Show, I will eventually turn on you. Imagine having a partner like that! The duo feuded with Kane and X-Pac over the tag team titles, which they won at Summerslam. By far the best part of the team was the theme music, which had a dread and doom feel to it. Unfortunately, the team was short-lived, as Undertaker got a serious groin injury in September, and took a leave of absence from the company.
