Tony Stark is a brilliant inventor and a playboy billionaire who gets what he wants no matter the consequences. And those consequences have huge impacts on his life and those around him. That was the reason why all his villains existed, why The Avengers split up and why The Vulture ended up existing in Spider-Man: Homecoming. Of course, Stark never intentionally does anything, but his actions have huge repercussions to those who are beside him. Stark’s actions also affect him the most, as it has been depicted through his Marvel journey, but the hero’s hand for wreckage ran far into Homecoming.
In the upcoming film, Adrian Toomes aka The Vulture has a small business cleaning up the mess that is made by the stupendous fights that superheroes have around New York. Toomes and his small team salvage from the debris. Stark stops their business, post-Civil war when he creates Damage Control which is hired by the government to take over Toomes livelihood. Toomes is not happy, to say the least.
Heroic Hollywood revealed what incited the formation of The Vulture and a life in crime. Out of anger for his business loss, Toomes and his team steal what they can find out of the Chitauri debris. They also began to harbor ill-feelings against rich men like Tony Stark that seem to get whatever they want in life.
Toomes’ character is somewhat altered from the comic-book which sees the villain as having beginnings in electronics engineering. He was in business with Gregory Bestman. Bestman handled the finances while Toomes handled the inventions. When Toomes created a flight harness, he eagerly rushed into Bestman’s office to share the happy news. Toomes discovered was not there and that Bestman had secretly been embezzling funds and that Toomes had no legal recourse, meaning he lost his job. Toomes wrecked the business in anger, discovering that the harness also granted him superhuman strength. He then decided to turn to crime professionally as the Vulture.
