Basic Trope: A power can be negated by something that would, logically, have an effect on it.
- Straight:
- Bob has the ability to create fire. Unfortunately, his power isn't as effective in low-oxygen environments (The ocean, the tops of tall mountains, Space, etc.), since fire needs oxygen to burn. It's also less effective in the rain, since water tends to extinguish fire.
- Far-Sighted Phil has Combat Clairvoyance, but he has to first identify something as a threat before he can react to it, so an attack that comes from absolutely nowhere can catch him flat-footed before he can react.
- Exaggerated: Even a tiny drop of water is able to render Bob useless that he has to stop drinking water or else his powers are ineffective.
- Downplayed: It's rather more difficult for Bob to create fire in suboptimal conditions for it, but he can manage.
- Justified:
- Once the fire is created, it's still fire, and behaves exactly like such. Bob can't avoid that many laws of physics.
- In an Everyone Is a Super world, every power comes with a weakness. This applies to Bob, too.
- For all his ability to predict an opponent's moves, Far-Sighted Phil can only counter an attack if he's aware that it's coming. So while he can easily evade an evidently dangerous person swinging a sword at his face, a No-Nonsense Nemesis taking a shot at him with a Sniper Rifle as he's relaxing and none the wiser is another story.
- Inverted:
- Required Secondary Powers than can be used like the prime power. Bob can keep himself warm in cold environments because he needs to generate immense heat in order to create fire. It's just a matter of re-purposing it.
- Logical Immunity
- Subverted: At first it seems like Bob is going to be ineffective in an environment with little oxygen, but then he reveals that he can also summon/generate oxygen.
- Double Subverted: The oxygen is summoned close to Bob's body, and he is not immune to his own fire.
- Parodied: The 'Logic' in 'Logical Weakness' is of the Insane Troll kind.
- Zig Zagged: Bob ends up in a low-oxygen environment, but turns out he can summon that along with fire. The oxygen is summoned near his body, but he's taken steps to avoid getting roasted by the fire. And then he faints because the fire consumed the oxygen faster than he could summon it. Later, he trains to make sure he can summon a larger amount of oxygen...but brings an oxygen tank, just in case.
- Averted: Bob has all the Required Secondary Powers to make sure that he can always use his fire power at any time and not get hurt because of it.
- Enforced: "We need to show that Alice isn't too overpowered. Why not have her powers become weak whenever she has to fight underwater?"
- Lampshaded: "I'm going to cook you alive with my fire power." "Not without oxygen, you won't." "Oh, This Is Gonna Suck."
- Invoked:
- Bob's fire is actually a manifestation of magical power that just happens to look like fire and thus doesn't naturally consume oxygen or have any effects that could harm Bob, unlike regular fire. However, Bob is a logically-minded person and still isn't used to magic existing on its own set of rules entirely separate from regular physics. Because he expects his summoned fire to be normal, he subconsciously shapes his power to simulate the effects and drawbacks of mundane fire; i.e. draining oxygen from the environment, producing a heat-like radiation that can harm Bob as well as his opponents, and things like that.
- Bob's fire isn't real fire and doesn't naturally do things like emitting smoke or consuming oxygen, but someone who feared what it could do cursed the magic to conform as much as possible to mundane reality, so now Bob's fire-summoning spells also have to summon smoke and radiant heat or else fizzle as reality rejects it.
- Bob's mentor is trying to teach Bob humility by limiting his ability sometimes so he wouldn't get too cocky and crazy if he got such an unstoppable power.
- Exploited: Alice lures Bob to environments where he won't be able to make good use of his fire powers to give her an advantage.
- Defied: Bob's power isn't negated by anything.
- Discussed: "Sure, that fire power you have is neat. But it's not without its' weaknesses, and enemies can exploit that. After all, you're not going to be able to use those fire powers in small spaces- you'd cook yourself."
- Conversed: "Bob seems to think his fire power makes him invincible. Obviously he's never heard of Elemental Rock-Paper-Scissors."
- Implied: Bob has an Oh, Crap! expression when it's announced that the final tournament is gonna take place above water or near a beach, and says "Why did it have to be water?!" then storms off.
- Deconstructed: Bob is a Squishy Wizard who is utterly helpless in environments where his powers do not work. This eventually gets him killed when he's in the wrong place at the wrong time.
- Reconstructed: Bob's sister Haley learns how to control the environment, and they become a Sibling Team; Bob works his magic, and Haley helps him do that when the weather refuses to comply.
- Played For Laughs: Bob's enemy tortures him all the time by using his limitations against him and flaunts her own advantage over him, "Oh, wait, I forgot you can't use your Mind Reading abilities on two people at once." *duplicates herself 4 times* "How about this?! HAHAHAHAHA, I'm so evil!"
- Played For Drama: Bob still tries to combat using his power even if his weakness harms his body in the process and is extremely frustrated at his own limitations holding him back from being stronger than everyone that he keeps destroying his body with his desperate attempts at overcoming his weakness and reaching his full power.
