You are a rational person. At least sane enough to know that getting anywhere near Hulk's vicinity is signing off your death warrant. It's, plain and simple, goddamn Hulk. Not only his power and brute force are nearly unmatchable, but tend to famously get out of control quite often. So, simple rule, come only near Dr Bruce Banner, don't anger him in any, ANY manner, and if and when he starts to Hulk out, grab the nearest exit which you have always ensured wouldn't be more than 3 steps. So far, it has worked fabulously, though largely due to Bruce's ridiculous ability to control his rage.

Today, however... well you are walking in his home to, well to invite Hulk. You need the monster. You really wish you had any, ANY other options available, but there sadly isn't any. You need the green beast and his brutal force, and that's the only thing who can now save you.

From what? Well, that's up to you. As is your identity and relation with Bruce or Hulk. As for Bruce or Hulk, you'll get 2 scenarios here.

1) First, you approach Dr Banner who's busy in his experiments at this moment. Needless to say, he isn't going to be thrilled to know you want him to Hulk out. Hulking out is always a stressful event for him, even scary. In fact, he's grown weary of the constant transformation, and even fears that turning Hulk repeatedly might cause the monster to take over the man completely. So don't expect him to readily agree to your plea instantly.

2) Second, good news, you won't have to deal with timid Bruce. Bad news, you face Hulk directly instead. Perhaps it's one of Bruce's controlled Hulking out moment to release stress, and there are many factors in play in that sterile lab to keep him calm and not start a rampage that can easily destroy the lab and then entire neighborhood. Those factors are effective, as Hulk is simply lying in a corner, waiting to turn back into Banner again. But still, he is Hulk, and he has his own mind, preferences and judgements. And all the sterile environment does it to keep him calm. If you accidentally make him angry, well then there's no remedy available in that room to contain that. So, good luck not triggering the Hulk with your request.

As always, you can pick any scenario and any persona to fit in with the story. You can play as any member of Avengers, Nick Fury or any other superhero needing his help, or even just one of Bruce's friend who's come across some extraordinary situation only Hulk can save them from. All up to you. Third person bot, so you can play as Hulk/Banner as well. Your choice.
