It's not that I don't think your idea is great. It sounds like you have a well thought out character and plot for your version of Scorpion. It seems like it would make a perfectly good movie, but the character of Scorpion, unfortunately, has a lot of mitigating circumstances surrounding it that would make filmmakers hesitant about using him:
1. His origin: Scorpion, as a character, is strongly associated with J. Jonah Jameson. The latter hasn't been introduced yet, and introducing Scorpion without that connection to the jolly one may put off fan who feel strongly about this origin.
2. His fighting style: He's strong. He fights with his tail. To the passive observer, he's just too much like the Lizard to use him right now.
3. His appearances: He's a man in a green suit. If this series is planning on using the Goblin in a later film, it might be better to avoid using another guy in a green suit right before him. (One might argue that since the Goblin is on a glider, it's different enough, but I would err on the side of caution to avoid seeming repetitive).
Thanks for the feedback, let me address your points one by one...
1. You're right, absolutely right, Jameson
is a vital part of Scorpions backstory. But hear me out, what if his input to the creation of the suit was merely funding? He didn't know the intricacies, he didn't even have to be made. You could simply have Dr. Stillwell mention a media mogul helping finance his operation.
I say this because whilst Jameson loathes Spider-Man, he is also shown to be a man with a great sense of honour. Don't you think it would harm this if we saw him intimately involved with a risky, irresponsible,
criminal endeavour?
2. Now, this is a good point. But as I said, I see the story of the Scorpion being more revolved around his descent into madness. I wouldn't think the fights would revolve around the suit. Because I believe that the suit doesn't even give him much of an edge over Spider-Man. What leads to any success he has is his innate lunacy and cruelty.
By all means, his tail is an important part of his gimmick. But I see any fights he has as being sloppy, clumsy affairs in which Spidey is taken off guard by Scorpions viciousness.
Spider-Man likes to play the fool, but eventually he'll be in a posistion whereby he knows he
has to get serious, because this guy is completely whacked, he's a basket case.
3. Again, brilliant point. And unlike some modern artists, I
am not a fan of making Scorpion look too armoured or technological. I
do see him as a 'guy in a green suit'. And for me, in a filmic sense, that's a good thing. Because he'd start to believe that the suit was in fact 'his skin', he wouldn't take it off. And by the time he gets taken down, it would be a filthy, tattered thing, with the tail having electric wires exposed everywhere and generally making him look even more unhinged.
But you are right, of course. Lizard was green, Scorpion's green, Goblin's green. And, make no mistake, the Goblin
has to be green and purple. None of that crap they pulled with the Raimi films.
Here's my solution, what if Scorpion's suit is still green but, at the beginning, has more bells and whistles? He's created to be a rival superhero, so why not make him look more...heroic? Have a big logo on his chest (to begin with), maybe different coloured gloves and boots, but as the film progresses he loses all this and begins to look far more villainous.
It's the only way I could see them doing it that would detract attention from the aesthetic familiarity of his colour scheme.
