Why couldn't he? Nul was a wreckless raging mind controlled beast. During WWH he was in complete control the whole time and used his brain aswell as his brawn.
As for beating the whole Worthy at once he ain't doing that unless he's at Worldbreaker levels.

The Worthy should beat him though. WWH is powerful but I think it would take someone above his power to beat a team of this caliber...especially when a group of them have haxxed powers. Hulk would go down fighting though.
