- Alternative Character Interpretation: Heres one for Iron Man and Mr Fantastic from before Planet Hulk even started: Iron Man has stated multiple times that they knew that the Civil War back on Earth would happen before anyone else did. Now, before the Civil War began, they, along with the rest of the Illuminati(minus Namor) also decided to send the Hulk away on another planet because they deemed Hulk to be too dangerous, which leads us to this storyline. However, what if Tony and Reed had another reason? What if their real reason for sending Hulk away was because they probably knew that Hulk would be more likely to side with Captain America than with them and because they knew that whoever would have Hulk on their side (again, most likely Steve) would have a huge advantage over the other side?
- Complete Monster: The "Red King", real name Angmo-Asan, seemingly saved Caeira's life in a flashback from the slaughter of her village before enslaving her in the comic and revealing himself in the cartoon to be the architect of the attack in the first place to take her as a slave. In his gladiatorial match against the Hulk, the Red King begins by slaughtering a group of the arena's survivors. Ordering the deaths of any who question the tributes he receives, the Red King dismisses the complaints of peasants, whom he compares to animals. In his rematch against the Hulk, the Red King tries to destroy the arena with a nuke, uncaring for the audience within the blast radius. When confronted about his atrocities, the Red King smugly proclaims killing to be his right, duty and pleasure. Finally defeated, the Red King tries to destroy the planet he is on as a final act of spite.
- Ensemble Dark Horse: The Android in the movie.
- Harsher in Hindsight: The inciting incident, Hulk's rampage in Vegas, is played lightheartedly in the issues it was depicted in. There was the tension of a stronger than usual Hulk going on a rampage as the Thing and Human Torch confront him, but that same tension is used to undercut the suspense with comedic turns. As far as was shown, the most damage was to property. Then comes the issues depicting the Illuminati deliberating on the matter and it's discussed that he killed 26 people and a dog on his rampage.
- Moral Event Horizon: The Red King crosses this in Caiera's eyes when he sets the Spikes against the Hulk and then bombs the village he infected with them.
- Too Cool to Live: Caiera.
YMMV / Planet Hulk
