Okay, woodcampers, Man-Bat gets another vote: 5 to 3!

If Man-Bat makes a frontal assault, it would have to do it before the Bear stands fully upright (which won't take long to do): if it is fully erect during the charge, the Bear will have superior reach with its long limbs. Arctodus was capable of slaying 2500 lbs Jeferson Ground Sloths by engaging them in face to face encounters, using its reach advantage to slice open the belly, or simply moving in and biting the neck. I think Man-Bat would go for the neck, and lash out ferociously with its claws before striking. However, this is a grave risk, one that could see its wing bones pulverized with paw swipes.
