Coming out of WrestleMania 36, much of the fan and critical chatter centered around two very creative and unusual gimmick matches: the Boneyard match between The Undertaker and AJ Styles, and the Firefly Fun House match pitting Bray Wyatt against John Cena.
So, who do we have to thank for these rather unorthodox productions?
According to Dave Meltzer on Wrestling Observer Radio, the Boneyard match was headed up by longtime WWE creative voice Michael Hayes. Meltzer also notes that Triple H was heavily involved with the planning, as was Jeremy Borash. Borash was the driving force (alongside Matt Hardy) behind the imaginative "Broken Universe" franchise when it came together in Impact Wrestling four years ago, most notably the chord-striking "Final Deletion" match between Matt and brother Jeff.
As for the much more eclectic Firefly Fun House match, Meltzer says that the creative leads for that were Wyatt himself and Bruce Prichard. His report does claim that Cena made a lot of changes to the segment that were reportedly "for the better".
