The main event was a Thunderdome match pitting Ric Flair and Sting against Terry Funk and The Great Muta.

Flair and Sting won when Funk and Muta's manager Gary Hart threw in the towel for his team.

[2] Ric Flair's feud with Terry Funk ended at Clash of Champions IX when Flair made Funk submit to the figure-four leglock in an "I Quit" match, then Gary Hart's J-Tex corporation began a full-scale feud with Fiair and Sting, but in early December Arn Anderson returned from the WWF and joined Flair, Sting, and Ole Anderson to reform the Four Horsemen.

Tommy Young's long refereeing career in the NWA ended in November, 1989, during a TV taping of WCW Saturday Night when Tommy Rich knocked Young to the mat and into the ropes during a match, legitimately injuring his neck.

In 2020, after 19 years since the acquisition of WCW, WWE revived Halloween Havoc as an annual event for their developmental brand, NXT.
