User blog comment:GSFB/Giant Short Faced Bear vs Man-Bat/@comment-3127606-20130205005124

I'm going with man bat here. He can fly, being able to fly will play tremendously to man bat's victory. He'll be able to swoop down, attack, then fly off before being seen. The GSFB is grounded, and even though he's taller than man bat when standing upright, bears don't especially like standing upright for too long. Another reason is the hightened senses. In a dark forrest, man bat will be far more effective as bats already see excellently in the dark. This is due to echolocation which they use to feed. Here though, it'll be used to kick ass.
