Then, Yusei defeats Aporia, using the combined might of the 3 Signer Dragons, which causes him to crash into the sea. Resultingly, Team 5D's wins the WRGP finals. Then, the red sky returns to its blue color, and the lightning strikes stop. Then, Team 5D's celebrates their victory during noontime.

When the Ark Cradle collides with the city's Ener-D generator, it will unleash a deadly shock wave from the impact, and a massive blast of negative Ener-D, which will destroy New Domino, Satellite, and everything else within the surrounding areas (which is basically everything within 30 miles of the Ark Cradle), which would be another Zero Reverse event on a much larger scale.
