heres my thought for scorpion and rhino...mac gargan is hired by jjj to investigate peter and how he gets his shots of spidey. Mac idolizes spidey, but certain events cause him to resent spider-man. he is so obsessed by his hunt for spidey that his wife leaves him. he is approached by a woman from a secret company who can "give him every ability that spider-man has...and more". he agrees, has the surgery to become a scorpion, hates what he has become. his insanity is compounded by the revelation that the surgery cannot be reversed. he blames spiderman for driving him to such lengths. many crazy cool fights insue. spiderman is completely outmatched, however during on of their fights Mac's wife an daughter are killed after Mac and spidey fall of a building onto their car. Mac is overtaking with guilt. spidey, knowing he cant take scorpion one on one. attempts to negotiate with him. peter convinces mac that it was the company that caused all the problems. they attack the company together. the president of the company (the same woman who approached mac earlier) gives the typical "crazy im-changing-the-world tyraid", declares project scorpion a failure, and reveals to them "project rhino". a giant human-cyborg hybrid that looks like a giant mecha-rhino. of course they fight, macs tail is ripped off, spidey gets his butt kicked alittle bit. but in end he wins because of his superior speed and wit.
its very similar to the scorpion/rhino story from the spidey 3 video game...and of course there would need to be other sub plots and such, perhaps introducing felicia hardy (not as black cat) and featuring gwen as the main love interest. maybe kill of captain stacy? causing gwen to be in love with peter but hate spiderman? im just spitballin here...
