#3 Hyped Debut
A surprise return, debut or appearance may be awesome to witness live but a properly hyped debut followed by cryptic vignettes or video packages is even better. You may remember Chris Jericho's memorable WWF debut in 1999 or the Wyatt Family's debut in 2013. Hyping up a grand debut may also result in increased ratings for the show, and Monday Night Raw surely needs to boost their ratings.
Kenny Omega could make his much anticipated WWE debut in such a way. Video packages prior to his debut highlighting his achievements in the Independent Circuit would be an effective way to introduce Omega to the casual Wrestling fans and make his debut feel big. That would be possible only if WWE finds a way to collaborate and make a deal with NJPW to acquire their footage.
