Tony Stark bought Coca-cola (it’s called Okie-cola in the comics but it’s clear what they were referring to) so that he could use the vending machines they have set up around the world to provide medicine to third world countries that have access to Coke but not Vaccines.
And he still doesn’t think he’s a hero.
Tony we need to have a talk about your self-image.
(This is all made much cooler by the fact that Coke in our world owns Dr Pepper, which is doing an Avengers heroes run with Iron Man on the can. :) )
