Lesnar is the former UFC Champion here, and him taking a Last Ride powerbomb but having the ability to hold on and lock in the Undertaker's own submission hold would be pretty amazing. If Lesnar uses the Kimura early and "breaks the Undertaker's arm," he'd be weakened enough to possibly pass out in Hell's Gate. If you want to make Lesnar an unbeatable badass that could do business down the line for up and coming badasses like Bray Wyatt and Roman Reigns, this is a solid idea.
