Downplayed: Fan Dumb accepts that Hiro is the good guy, but they still tend to over-exaggerate some of the bad things he does.
Wanting to create realistic characters, an author gave Hiro some flaws he was supposed to overcome in the process of Character Development. Meanwhile, Draco in his first appearance briefly pretended to be a nice person. Unfortunately, for some fans. the first impression turned out to be too strong.
Subverted: The fans initially play down Hiro in order to build up Draco, but a Crowning Moment of Awesome on the part of Hiro, coupled with Draco's crossing of the Moral Event Horizon, convinces them that Hiro actually is the hero and Draco an irredeemable villain.
Double Subverted: Some of the fans still insist that Hiro is just pretending to be a hero in order to ruin things for the misunderstood Draco.
Parodied: Alice, writing a Fan Fic for Fantasmic, simply copy-pastes a transcript of one episode with Hiro and Draco's names switched. This fanfic In Name Only becomes insanely popular.
Zig Zagged: As the story continues being written, Draco crosses the Moral Event Horizon and the Fan Dumb returns to worshipping Hiro. Then Carmen starts dating Hiro when the fans want her to dateLance instead, so Hiro is demonized again. Carmen eventually breaks up with Hiro to date Lance and Hiro approves, so he's forgiven again.
Averted: The fans remember that Hiro's the good guy and that Draco is the villain.
Lampshaded: "You'll never please these people, Hiro. Draco has them wrapped around his little finger."
Invoked: The character who narrates the story doesn't like Hiro for whatever reason, and his negative perception of him colors his portrayal when he/she is asked to tell the story.
Draco's flaws are ignored while Hiro's are focused upon and made out to be far worse than Draco's monstrous actions. After putting up with this for some time, Hiro gives up and leaves Draco's apologists to their grim fate. Even in their last breaths, they curse Hiro for not saving them rather than berate Draco for his behavior.
Alice's willingness to fangirl over the handsome but villainous Draco and demonize the virtuous Hiro on their series is reflected with her poor judgement in real life. She stays with her Jerkass boyfriend Drake and decries her friend Bob when he tries to help her out of the bad relationship, pointing out his flaws while ignoring Drake's...
A) ...To the point where Bob has to kill Drake in order to convince Alice otherwise. B) ...To the point where it takes Drake cheating on Alice in order to convince Alice that he was no good all along.
Alice actually distinguishes reality from fiction pretty well. She fangirls over Draco despite his villainous nature and isn't a big fan of Hiro, but she stands up to Drake and dumps him when he turns out to be abusive, and she is good friends with Bob.
