The opposite idea to the previous entry, but it works in a similar way. This one would see him joining the Vision, Black Widow, Black Panther, and War Machine in getting behind Tony Stark and the pro-Accords team. In terms of the MCU, Iron Man is probably the most famous hero around, ever since he announced himself to the world way back in the first Iron Man film, with Tony Stark himself something of a celebrity anyway. So, if you're a young hero, and you see both the government and this superhero icon in favour of regulation and accountability, it wouldn't take much for you to join that side as well. In the trailer, when we get our first look at Team Iron Man, some fans have even suggested the notion that Spidey is there with him, just to the right of Black Panther. That remains to be seen, and seems more like wishful thinking at this stage, but him siding with Iron Man is a very distinct possibility.
