Alright, here it goes.
Venom is at the construction site just waitiing for Spidey to show up, ahving tied up gwen and MJ. Spiderman figures that its going to be one on one till Sandman(lime OMG) forms from out of nowhere, from seemingly a few grains of sand scattered at his feet. Venom beats down on the Webbed Wonder digging into him with backfists and haymakers and whatnot whilst trapped in Sandman's solidified form.
Spidey breaks free and dances round the battlefield, dodging Venom-webs and Sandman's constant "anvil-hand" punches that we all know and love from the comics. They get the upper hand till Sandman gets pwned by Spidey, knocking him into next week. Venom now pounces into him, taking advantage of the weak Spidey. It looks like he's gone for the count until GG2 (Lala Harry Osborn) shows up and throws down teh gauntlet with some bombs and rockets to Venom. Also Harry comes equipped with a sonic gun(OMG) that his labs developed for...stuff.
The fight with Venom rages on until Harry puts up the ray gun. Venom is too quick, however, and impales Harry on a lead pipe near trhe site. Spidey reaches for the gun in time, and blasts Eddie's better half to kingdom come. Eddie and his captured cohorts fall into the abyss, falling fast form tiptop most placing on the battleground. In split second thinking Spidey saves one or the other or both(depedning if Gwen/MJ lives) whilst Eddie goes splat ohnoes bye bye.
Sandman doesn't die but is put into captivity, Teh End.
