I'd have La Parka debut on RAW to start the show and immediately cut a scathing promo in Spanish calling out Roman Reigns, who is the Universal Champion. The crowd is dead silent in awe of this spectacle. The Big Dawg comes out and tells La Parka to put his dinero where his mouth is and challenges him to a Mask vs. Title match later that night on RAW. La Parka wins the Universal Championship in a squash match to win the Universal title. He also cuts Roman Reigns hair to add insult to injury. RAW ends with La Parka playing the guitar on the Universal title.
Then the next night on Smckdown, La Parka is sitting in the front row wearing a giant sombrero while rocking the Universal title around his waist. AJ Styles comes out and asks him what the hell he's doing there & challenges him to fight. La Parka cuts a promo in Spanish saying he will fight if AJ Styles put the WWE Championship on the line. AJ Styles accepts the offer. La Parka comes out to the ring like this:
As soon as the bell rings, AJ Styles immediately falls to the ground & La Parka pins him unifying the championships. AJ Styles then gets up and embraces La Parka. AJ Styles announces his Latino heritage and how he grew up idolizing La Parka. He wants to reform the LWO. La Parka initially goes along with it, then grabs a chair & decks AJ Styles and the referee with it.
He then grabs a mic, speaking in clear English says the brand split is over. The show ends with a camera shot of Sting sitting in the rafters like
