John Cena just became the first 17-time champion in WWE history after beating Cody Rhodes at WrestleMania 41 ... but he didn't do it alone -- he got a bit of an assist from Travis Scott in the process.
The main event just went down at Allegiant Stadium in Las Vegas ... with Cena and Rhodes brutalizing each other as the former looked to surpass Ric Flair as the most decorated wrestler in the organization.
Mid-match, La Flame showed up and made a lengthy walk to the ring to help his buddy, Cena .
