A emotionally volatile tachycardic finds a way to calm his nerves, giving him unusual abilities, only to find the greedy dangers of a rich influential man prepared to anything to get those abilities to enhance himself for city domination.

Agree with Richiev. This is incredibly vague and longwinded. We need more specifics to understand the story. Is the method of calming his nerves a pill? A drink? A state of mind? A breathing technique?

With any superhero story, the inciting incident is (in my opinion) the appearance of the super villain. Since most superhero stories?are all about stopping the bad guy it makes sense for the inciting incident to be closely connected to this. Whilst getting the powers is an important part, it’s how they end up using them that keeps the audience entertained and is actually where the story is.

Why does the rich influential man want city domination? A good way of making sure your antagonists are as 3 dimensional as your protagonist is to write a logline from their perspective too. They must have a rational motive that an audience, whilst they might not agree with, can at least understand. Like Thanos in Infinity War!

Hope this helps.
