The Overseer (David Dunn) vs. The Beast (Kevin Crumb)

They're going to settle this once and for all... Except this time there will be no interruptions.

Fight takes place in an indestructible and inescapable cage that is 20x20 feet. Kevin is fully beasted out, and David has embraced his abilities.

Fight to the death or KO. NO weakness exploitation.

I thought Glass made it clear that David > Beast one-on-one:

The only way for Beast to gain the advantage was by exploiting David's weakness. Barring that, David would've beaten him to a pulp.
