Maybe GoldGoblin....just maybe you're right.
Here's a scenario....
Harry Osborn takes on the mantle of "Green Goblin the second" (hehe...sue me) and goes directly after Peter Parker with "his" version of the Goiblin gear and suit. Peter is just about to propose to Mary Jane, when oops! a pumpkin bomb hits his apartment, and out of the window he goes (as in the trailer), but fails to catch the ring in time. Harry crashes into the wall (like in the trailer) after trying to hit an unsuited Parker, as Parker jumps back into the apartment, rips off his clothes to reveal his new "Black Spidey" outfit, and the two do battle in the sky. Parker is easily beaten by the anger-fueled Osborn, and Harry imeediately leaves after his Goblin attire is damaged by Parker! When back at his manison, he throws away the suit and now-broken glider. He thinks long and hard about what he just did, and hates himself for it.
Onto the Battle royale...(while Spidey does battle with Sandman and our favorite...Venom!)
Harry feels terrible still about almost killing his best friend, when MJ arrives at his house, she has a plan to save both of their lives. (Peter's and Harry's) She tells Harry that she knows he is still good, and that he is the only one who can save Pete, so Harry immediately enters his father's Goblin lair, destroys everything but a few pumpkin bombs, and his father's old Green Goblin suit. he puts on the evil suit (because it will protect him better than the previous one) without wearing the mask, and jumps on the REAL Goblin glider, and heads for the construction site. When he arrives, Peter is about to bite it, Sandman is dead, and Venom is there, slowly injurying Peter. Harry swoops down, and kicks Venom out of the way. But our friend Eddie Brock/Venom is not yet out of the competition, and strikes the good Green Goblin, with a blow right through the chest, into his heart, instantly killing Harry Osborn. Peter screams, jumps over Harry's dead body and begins to kick the ***** out of Venom. They are evenly matched, but Parker manages to give the final blow to Venom, with the symbiote leaving Brock and disappearing into the nearby river (under the Queensboro Bridge), with Brock's almost dead body laying on the ground, unconsious (sp?) and all. Peter holds Harry's crippled body close to him, cries, and we fade to black....
Fade to Queens Jail House.
Eddie Brock is being drug into a jail cell, and is locked away. But he has a cellamate.
Cellmate: Yo! Hey! You awake?! (Brock awakens)
Brock: Where am I? Who are you?
Cellmate: You're in jail kid, and my name....is Cletus....Cletus Kasady.
