SM5: Electro/Vulture/Shocker
In the beginning of the movie have spidey respond to an alarm going off where spidey encounters the "Shocker".Then after spidey defeats him we see reporters on the news talking about how spidey has defeated another criminal who was armed with equipment that was made from "The Tinkerer".
Then show the t.v. go off and the camera pulls back to show an old guy in a jail cell.The old guy is the criminal who the media has nick named "The Tinkerer",because this guy creates all kinds of tech gadgets and then sells them to criminals,making ordinary thugs harder for the police to take down and giving spidey more of a challenge to take out.
Have "The Tinkerer" on death row,and he is about to be executed,show the guards shave his head,and then the guards take him down the hallway to the electric chair to be executed.
Have one of the guards (Max Dillon) be really evil,but only to all the inmates at the prison,show this guard beat them,harass them,torture them,call them names,etc.
And this guard is the one who always gets to hit the switch when the inmates are executed,that why the inmates gave him the nick name "Electro".
All the criminals in N.Y. do not want "The Tinkerer" to be executed for obvious reasons,he supplies them with equipment that gives them power,and gives them a fighting chance against Spider-Man.
As the guards are escorting "The Tinkerer" into the execution room,one of the guards is dirty and pulls out a gun and starts shooting the other guards.
Then Max Dillion who is standing on the other side of the room runs over and grabs the guard with the gun from behind,but the guard ends up knocking Max off of his feet,and Max falls back into the electric chair.
Then as Max is sitting in the elctric chair as the other guards are wrestling with the dirty guard,the gun goes off and the bullet hits the electric chair,causing it to fry Max.
But instead of Max being killed because the chair wasn't working right since the bullet messed it up,the chair turns Max into a human electric chair.
And out on the streets,"The Tinkerer" builds himself a suit,and the media nick names him the "Vulture".
In the beginning as Electro first has his superpowers,Electro considers himself as an actual superhero,and he is obssessed in finding "The Tinkerer aka the"Vultrure".
And he wants to finish what he started,and that is to kill "The Tinkerer aka,the "Vulture".And that is when spidey becomes Electro's target as well.Since spidey doesn't want Electro to kill "The Tinkerer" aka,the "Vulture",Electro decides that spidey is just as bad.
