Gold Strike: Spiders: Iron Man 2

Tony Stark and his son Jackson "Jax" Stark have just outed themselves as Iron Man and Gold Strike. The world can't seem to let it go, and they're reveling in every moment of it.
When Tony realizes that the arc reactor in his chest is slowly killing him, he does not let Jax know, because he had just rebuilt a relationship with his son, and he doesn't want it to change.
But when villains are out there aiming to take both the Starks down, a trio of specially trained assassins/fighters called The Spiders come in to help make sure that neither of them die. Mother Natasha Romanoff is known as Black Widow, or her alias in Malibu as Natalie Rushman. Her twin daughters, Anastasia and Tatiana Romanoff, are known as Arachne and Tarantula. They aim to cure Tony of his sickness eventually, with the help of the one and only Nick Fury, who wants Jax to join and even more elite team of superheroes called the Avengers, and also wants to see if Tony can still be useful to them even if he is still dying.
