I've posted a number of scans below showing what Supergirl can do over the weeekend. We've seen her strong enough to overpower Martian Manhunter (although he did fight like an idiot) and fast enough to steal GL's ring right from under him as well as race the Flash. Last but not least, there is considerable support here for the theory that due to her being exposed to solar radiation at an older age, she is actually stronger and faster than her cousin Superman.

Thor of course needs no introduction.

So... who wins this battle ?
Does the battle hardened warrior from Asgard prevail over this snotty little teenager or has Supergirl inherited her cousin's mean right hook (and we all know what that can do) ?
