Ok here are my ideas for how I would treat Doctor Octopus in the movies.Basically these ideas are inspired from ASM#3,Spider-Man 2,and the episode 'Doctor Octopus:Armed and Dangerous' from the 90's cartoon show.
I would have Octavius introduced as a scientist working for a major scientific research company [not Oscorp].I don't want Octavius to have any ties to Oscorp.I didn't have a problem with it in SM-2,but I personally would
prefer if he was working in a seperate independant company.
Doctor Otto Octavius is one of the country's top 10 physicists,specializing in the areas of nuclear fission and fusion.He has spent the last 10 years of his life doing ground breaking research in the area of fusion.He believes fusion reaction can be generated in a battery,thus providing an amount of power so great that it could replace dozens of nuclear power plants.
Though his peers are skeptical of some of his radical ideas,investors and other major researchers financing his research work have been impressed with his progress over the past 5 years,and want to see more.
Otto Octavius is known among his colleagues as an extremely arrogant and egotistical man.Though his dedication to his work is admired,his unpleasant manner and attitude towards others makes it very difficult to work with him.
Now the infamous introduction of his tentacles would be done like this: I would have some young poor sap lab assistant bringing some chemical or whatever to Octavius' lab.I would have him meet some of the other scientists on his way,who say something along the lines of "Are you taking that to Doctor Octopus?? His lab is on the 3rd floor".And of course the lab assistant would quiz as to why do they call him Doctor Octopus.To which they'll simply remark "You'll see when you get there".When the guy get's there,he sees the tentacles on a little platform with a control panel,similar to that in SM-2.
Unable to resist his curiosity,I'd have the young lab assistant go over to look at them,and just as he is about to touch them Octavius interrupts with a vicious warning that if he does touch them,it will set off a deadly security system,as the arms are under a security locking system which can only be unlocked using Octavius' hand on a scanner panel.
Now for the Peter Parker connection.While I know they never met in the comics prior to Octavius becoming a super villain,I had absolutely no problem with Peter knowing Octavius before he became Ock in the 90's cartoon.And it was used very effectively in it.SM-2 had the opportunity to do something similar,but instead wasted it with talks of love poetry and other BS in an attempt to make it feel personal between Peter and Octavius for when Octavius becomes a villain.That is not the nature of their relationship.The most Peter should feel for Octavius is respect for his great scientific mind.Looking at Octavius as his scientific idol.Nothing more.It is not personal between Spider-Man and Ock,unless Ock does something that personally affects Spider-Man's life,like the Aunt May debacle or bashing Black Cat to near death.
Now in my movie,Peter will be a keen admirer of Octavius' work for years.And similar to SM-2,Peter will have a paper or project to do on fusion,and in turn manages to arrange a meeting with Octavius with the help of Curt Connors,or possibly from Harry thru Oscorp's connections.When they meet,Octavius is thoroughly irritated to have to waste his precious time entertaining students.However Peter tells him he's been a great admirer of Octavius' work for years.Not so easily convinced,Octavius would say something like "Really?? So you've read all my published papers then??".Peter would reply "Of course.Sustained fusion fission reactions,neurochemical fusion".And Octavius would say casually "What about Fusion potential of the super collider??".Peter would look confused for a moment and say "You never wrote that.You were testing me weren't you??".And Octavius would offer his first genuine smile "And you passed".
From there I would have Peter demonstrate his knowledge in the area of fusion,and have Octavius seem genuinely impressed with this keen young man who seems to have a genuine interest in science.In fact in their discussion I might even have Octavius make a reference to his young days when he was learning about this stuff with great enthusiasm,much like Peter.Just to show the similarities between them.Also I think by having Peter meet Octavius,it gives him a better understanding of the man.
Now for the transformation to villainy.Octavius has learned that he has been given the green light to demonstrate that the fusion reaction can be generated in a battery.They seem so convinced by his theories that they're willing to see a demonstration.So there's a major demonstration,similar to that in SM-2,where various investors,researchers and other scientists in the field have come to witness Octavius' big breakthrough.
In the demonstration,we would see Octavius unveil the tentacles,put his hand on the little panel scanner,unlocking the security mechanisms.He would then explain the purpose of the arms,in that they do contain an artificial intelligence programmed to control and sustain fusion reactions.But they are NOT smart enough or capable of messing with his mind or influencing his actions in ANY way.The arms would plug into his spine exactly like in SM-2,with the same tentacle look and design.
Octavius would be standing behind safety glass to protect himself from the heat of the reaction.There are specially designed slots in the glass so the arms can pass thru to manipulate the fusion rection."With these smart arms I can make fusion energy my servant".I might even have a few people whisper to eachother "Doctor Octopus goes to work" as he starts using the arms.
The fusion reaction is fired up,and Octavius begins to increase the size of the fusion reaction.The bigger it is,the more power it can generate.However the safety alarm begins to sound,as the reaction is beginning to give off intense heat and energy bursts.The lab technicians and other spectators begin to clear the room in panic,as security guards come in and go to unplug the reactor chamber.Octavius spots them and viciously swipes them away with a tentacle,believing he can cause it to stabilise,believing he has it under control.However the energy intensity becomes too great,and the fusion chamber explodes in a burst of heat and energy.
Octavius survives,and is taken to an expensive private hospital courtesy of his company,who are trying to keep the accident hush hush.However the press get wind of the explosion,and Jameson sends Peter to try and get photos of the injured scientist Otto Octavius,as he believes there's some big cover up going on,and he wants the scoop on it.
Meanwhile in the hospital we learn from the doctors who have X-Rayed him,that Octavius' metal arms have been fused to his spinal chord as a result of the accident.He has some second and third degree burns on his chest and torso,and some minor trauma to his head and neck as a result of the explosion.Octavius awakes in a private hospital room with IV drips,heart monitors and other medical equipment attached to him.He demands to know where he is and what's happened.One of the nurses brings in two of his work colleagues,who briefly explain that the fusion reaction went unstable,that he took it too far,endangered many lives and cost the company hundreds of thousands of dollars in damages.Not to mention the media is making a huge frenzy out of it.They're trying to hold off a horde of reporters at the hospital gates.They tell him that the investors have pulled the plug on his research money,and that the company is shutting down all his projects for the forseeable future.
Octavius protests in anger that they cannot do this to him.It's his life's work,his precious research.But his colleagues tell him that it's done.And that he may want to get a lawyer because several of the company exceutives and investors are suing him for his careless actions and endangerment of human life.
After his two colleagues leave,Octavius is left to stew in his bed at what has just happened.Two doctors and a nurse come into his room shortly after and tell him that they need to prep him for surgery tomorrow,as he has an unknown amount of spinal damage,and they need to remove his mechanical arms as soon as possible.Octavius refuses,saying he needs to leave here and retrieve his research data from the filthy parasites who intend to take it from him.But the doctors tell him that's impossible.He's sustained very serious injuries and that he must stay in bed.
At this point Octavius has reached boiling point with his anger.He says thru clenched teeth "You dare to tell me what to do.Do you think you can keep me a prisoner here?? Do you think you can keep me from my precious work,like those other fools are trying to do.DO YOU?!?!?".At that point his 4 mechanical arms come to life and lash out with the speed of thought swiping the two doctors against the wall with such a force that it renders them unconcious.The nurse flees in terror from the room and hits a silent panic alarm on the wall alerting security.
Octavius rises from his bed,propped by two of his tentacles.He watches with extreme amusement as they move around him at his very thoughts.As though they were his own flesh and blood arms."I can feel you" he almost whispers to them."I can feel you as intimately as I feel the flesh I was born with".
He then strides out of his room on two tentacles and down the hospital corridor.At the other end of the corridor 4 security guards are approaching.Two of them rush at Octavius to try to subdue him.But he merely grips them each in a tentacle before they can get remotely close to him.He then snaps their necks like twigs.The other two guards open fire on him at seeing this.He easily deflects the bullets with his tentacles,as he moves swiftly down the corridor at them,and sends them smashing head first into a wall.
Octavius then turns and finds several of the staff fleeing down the other end of the corridor towards the elevator.Moving swifly on his tentacles,he flexes out a tentacle and smashes the elevator control panel before they can use it.Cowering in the elevator,Octavius advances on them and smiles wickedly."If you'd all be so kind as to follow me and do as I say,you may yet live thru this night".
Meanwhile outside at the main hospital gates,the press are still being held off by the security gate guards.Parker decides enough is enough,and he is going to get pics of Octavius in his own way.So he slips off and changes to Spider-Man.He then easily scales the fence and makes it to the hospital building unnoticed.As he's scaling the hospital wall,he hears some faint female screams and shouting coming from one of the hospital labs above.He then feels his spidey sense tingling,which leads him to the window in question where the commotion is coming from.
Peering thru the window he sees several nurses,doctors and a janitor cowering on the floor in a corner.The camera then pans along as we see two tentacles wavering at them,almost look at them.Then another two multi-tasking on a lab bench,pouring and mixing chemicals in beakers,heating some of them over a bunsen burner.While Octavius himself,now dressed in a simple business suit,is standing with his arms folded,as he observes his hostages in the corner,while he briefly glances back at his little experiment on the lab bench.
"Please Doctor Octavius" one of the doctors says."We've gotten you some clothes and the materials you asked for.When will you let us go??".Octavius waves a hand at him contemptously."Not until I'm ready.Your second rate lab will be useful to me to for making several chemicals I shall find uselful in my forthcoming venture.And you shall all remain here as my hostages to ensure I am not interrupted".
"But this is crazy.The police will soon hear of this.You can't keep us here much longer.You have no right....".The doctor's sentence is cut off as he is lifted off the ground by two of Octavius' tentacles,and dangled helplessly in front of him."Right?? You
dare speak to me of right.I have the right to do anything as long as I have the power.Power is everything you simple minded fool.It can shake the world to it's very core.And if you doubt
my power,then here is a small sample".
At this point Spider-Man decides this would be a good time to interrupt before Octavius really hurts that doctor.He bursts in thru the window and says "Hold it Doc,how about picking on someone who can fight you back".
Octavius tosses the doctor aside and faces Spider-Man."Spider-Man,the costumed fool who crawls like the insect he is.Well I shall be very glad to crush you for this transgression"."Tell me,are you a Three Stooges fan?? Your haircut just screams Mo Howard" Spider-Man quips.Octavius attacks him with two of his tentacles.Spider-Man flips and dodges them,and in his cocky arrogance makes some quip about Octavius being too slow to hit him,but he is suddenly knocked backwards by a powerful blow from a third tentacle which caught him off guard.
"Troublesome fool.You should have fled while you had the chance" Ock says as he tries to snare Spider-Man with two tentacles.But Spider-Man shoots his web binding two of Octavius' tentacles together.However to his surprise he easily snaps the webbing as if it was string.Cornered,Spider-Man is snared in Octavius' tentacles,as he is reeled in and is helpless before Octavius,who b1tch slaps him across the face and sneers "You dared to mock me before.Why aren't you mocking me now?? Where are your brave words and taunts now Spider-Man??".
Octavius then carries Spider-Man towards the window and tosses him out shouting "You may leave the way you entered.You're no threat to me".Spider-Man hits the ground outside,defeated and humiliated.Meanwhile Octavius decides to flee the hospital,as his hostages have escaped during the battle with Spider-Man.He smashes thru a wall and scales down the building and makes off into the night.
Ok that's all I have so far.Comments,criticisms and whatever else you all have to say about it would be appreciated

I shall post the rest of my ideas on what Ock get's up to,how he names himself Doctor Octopus,how Spidey names him Doc Ock,and how he defeats Ock.
