Since the chances of Hulk getting another solo feature are kind of slim at the moment, would you guys prefer for most of his story to be wrapped up by the end of the Avengers?
No. As long as The Avengers is not a flop, Hulk will appear in any sequels. Ruffalo signed for five or six films.
Also; has Bruce ever gain some type of control over his Hulk transformations in the comics as of late? I was just wondering since I wanted to know if it would ever be a possibility for the Hulk and Bruce to ever peacefully coexist with each other.
In the comics of late Banner and Hulk seem to have some type of agreement and each one allows the other to do what they do best.
Right now he's about as smart as he was during his Worldbreaker persona, but more rational and acting like Banner moreso.
This Hulk is the same Hulk that has been written for the last 7 or more years. He's not Banner at all (mentally) but he does show high intelligence at times and has been seen breaking down physics to his foes as he beats them up.
Speaking of which; if the Hulk is actually given some personality and treated as a entirely different entity in some aspect for this film, how would they go about it?
If they read The Incredible Hulk comic from issue # 77 on to present or watch The Avengers Earth's Mightiest Heroes show, that's how it should be done.
If you haven't realized by now, I'm not familiar with the Hulk as I am with other comic characters, so I'm just wondering if the Hulk as himself (no Banner influence) is someone who is just misunderstood, or a being that actually likes causing chaos and havoc?
Depending on the incarnation, but all Hulks are supposed to be "misunderstood monsters." They all tend to be surly individuals who don't take crap or orders from anyone.
Where I find most writers and fans who don't know the Hulk, but know of him make the mistake with Hulk, is not understanding that Hulk doesn't go looking for or causing trouble. He tends to mind his own business but he doesn't take kindly to being threatened...by anyone.
I would have figured that the reason why the Hulk is so aggressive is because from the moment he was created, the first thing he was exposed to in the MCU was violence and aggression.
There's been many reasons stated as to why Hulk is aggressive, from the gamma energy surging through him causing him to constantly burn, because of the way he received his dosage in the comics from a nuclear explosion, to the fact that he is surging with so much power that it's hard to keep his cool.
The Hulk was violent from the get go because, supposedly, that Hulk persona represnts all of Banner's frustrations and rage.
This is one of the reasons stated too. Banner's mother was killed by his father, who always figured Bruce was a mutant, because his father was working around radiation. Bruce's father believed this, because Bruce as a young toddler seemed unusually intelligent. After the event which caused his mother's death, as a child, Banner was scared to show any type of emotion because of the way he viewed his father. Banner became an introvert, all his life never showing any until he accidentally killed his father (or did he?), and the time after that was when he became the Hulk. So now all of that emotionally pent up repressed mental scarring, anger, rage, sexual tension, love manifests itself as Hulk's ability for endless strength.
