Fixing Characters That Don't Make Sense
Below are some suggestions for character fixes. This is not focusing on characters who are "overpowered," but rather, characters who's class or abilities do not make much sense.
Character: Iceman
Fix: Immunity to Incinerate
Reasoning: Why is someone covered in ice immune to incinerate? This makes absolutely no sense in any way. Fire melts ice...I don't think this one needs much explaining.
Character: Green Goblin
Fix: Class and Regen
Reasoning: There are two problems with Goblin. The first is that he should be science class rather than tech. The main difference between science and tech characters as a whole is that tech characters would not be the same without their technology, while science classes get their major abilities from some scientific feat. For example, if you removed Iron Man's armor or Star Lord's enhancements, they would basically be an average human. Green Goblin's abilities come from a scientific serum. Take away his glider, gun, and bombs, and he is still super strong with enhanced reflexes, and is criminally insane, which is what makes him so dangerous. These abilities come entirely from a serum that is inseparable from the character.
The second issue with Goblin is his regeneration ability. There are plenty of other characters who, like Goblin, heal much faster than average humans due to their enhancements. Spider-Man and Captain America are among these characters. The regeneration ability, however, should be restricted to characters who can meaningfully heal in the midst of combat to the point where it would make a realistic difference. Goblin has enhanced healing, but if you stabbed him through the arm, he would not heal during the fight in the same sense that Wolverine/X-23 do. In other words, his wounds do not close immediately.
Character: Magneto
Fix: Magnetism not affecting certain characters
Reasoning: There are many characters who should be affected by Magneto's magnetism that simply aren't. All of the characters I will list primarily use metal as a part of their armor or weapons: Deadpool, Deadpool X-force, Gwenpool, Punisher, Punisher 2099, Star Lord, Rocket Raccoon, Drax, Archangel, Electro, Antman. If I missed anyone (or incorrectly included anyone who is already affected) please let me know. I am unsure of whether Green Goblin or Dr. Octopus are magnetized but they certainly should be if they aren't already.
Character: Falcon, Crossbones
Fix: Should be Tech
Reasoning: As stated earlier, tech characters are those who, without their technical enhancements, would not be able to fight as they do with them. Take away Falcon's armor, wings, and Redwing drone, and he is a normal soldier. Falcon's wings are the reason he is, well, Falcon. What is he without them? He should absolutely be classified as tech. This exact argument could also be made for Crossbones and Antman. Crossbones needs his suit to fight, otherwise he is just a soldier.
Character: Rocket Raccoon
Fix: Should be science
Reasoning: Following the above logic that science characters are inseparable from their augments, Rocket Raccoon should be classed as science rather than tech. His is a normal raccoon that has been augmented through experimentation, giving him the abilities to walk upright, talk, and wield weapons.
Character: Various
Fix: Reclassification
Reasoning: I'm sure no one wants to keep reading about the logic for character class so I will keep this one short and sweet. Yondu is alien, and there's no way around that. He should be cosmic. Agent Venom should also be cosmic, matching Symbiote Spider-Man, Venom, and Carnage. The three Inhumans: Quake, Karnak, and Black Bolt, all get their powers from the same Terrigen mist resulting from alien experimentation. Whether or not this is classified as cosmic or science (I would personally pick cosmic), they should all share the same class.
Thank you all for reading this post! I am open to more suggestions, so if you can think of something I have missed, or disagree with entirely, feel free to add it in your reply! Just make sure you back up your argument with some logic.
