The Ronin here,

After all of the reboots and reviews and the like it's time to look back at another wacky villain. This one is pretty recent and comes to us from the "Brand New Day"* era Spider-Man comics. This villain is so mind numbingly, painfully bizarre she had to end up here. Honestly I don't know what to make of this villain. (But she is probably not based on a mass murderer so that is a bonus) It is Ms. Web 2.0 her self,
Screwball.
So who is Screwball? That is a damn good question. Screwball appears to be a young woman in her 20s, physically fit and skilled in the sport of 'Parkour'. (and yes, there was a bad pun based around the fact it sounds like Parker) A kind of urban gymnastics, involving running, scaling obstacles quickly, performing tricks etc. It is impressive stuff for sure in the real world... In a world populated with super heroes? less so.
