I've been a big supporter of the Croc but the Polar Bear is a fearsome predator and a proper nawty boy. Nothing really deters a Polar Bear apart fom a high powered hunting rifle.
I might wait a bit a read some well reasoned arguments for both before casting my vote.....
EDIT * well...
Seriously, I'm sure some on here want the NSC Worlds hardest creature final to be contested between a silly fluffy bird and something that resembles Pepe le Pew. :ffsparr:
The Croc ''can'' go a year with out eating, that doesn't mean that it does. If it hasn't eaten for a week it still has the hardness and strength to take down a buffalo for a spot of breakfast .
The HB would be a bag of bones or someones else' s lunch if it didn't eat for a week.
