In many ways, Tony Stark's actions in the movies themselves prove he has a heart. For example, his decision to sacrifice himself in 'Avengers: Endgame' was a selfless act that showed his deep love for the universe and its inhabitants. In fanfiction, this can be explored even further. Writers might depict his internal thoughts and emotions more deeply, showing how his experiences, like his time in captivity in the first Iron Man movie, shaped his sense of compassion. They could also show his relationships, such as with Pepper Potts and Rhodey, and how his love for them influenced his actions and decisions. Fanfiction often delves into the unspoken aspects of a character, and for Tony Stark, it can be used to highlight the very essence of his heart.
Well, in fanfiction, one key instance could be when Tony is faced with a moral dilemma. For example, he might have to choose between saving a large number of civilians or getting revenge on a villain who wronged him. If he chooses the former, it's proof of his heart. In the official MCU, he often made such selfless choices, and fanfiction can echo and expand on those moments.
Love is also a big theme. It could be romantic love, like his relationship with Pepper Potts showing a softer side of him that proves he has a heart. Or it could be platonic love, such as his deep friendships with the Avengers and how he cares for them in the fanfictions.
