'''Basic Trope''': Love is the Strongest Force in the Universe.
* '''Straight''': The heroes' love for each other lets them overcome their trials.
* '''Exaggerated''':
** The heroes embrace each other as they are [[BurnTheWitch set on fire]], and when the fire dies down the heroes are unharmed.
** Their love becomes an actual, tangible weapon or forcefield.
* '''Downplayed''': The heroes' love for each other is a powerful motivator for both.
* '''Justified''':
** The villain [[BreakingSpeech tells the hero that his love interest betrayed him]], but the hero doesn't believe him, and doesn't fall for the villain's trap.
** The setting's deity (or one of them) has TrueLoveIsExceptional as a "pet trope."
** [[WhatIsTHisThingYouCallLove The villain holds no love in his heart; it's something horrifying to him]]. The hero and heroine do. [[EvilCannotComprehendGood The villain becomes too enraged and confused to fight them properly]], and [[GoodHurtsEvil their affections cause him physical injury]].
** The Power of Love" is simple extreme devotion towards a goal or person. Other emotions, such as hatred, would grant the same magnitude of power.
* '''Inverted''':
** {{The Power of Hate}}. (Hate is the Strongest Force in the Universe.) The hero's overwhelming hatred for the villain and all the horrible things he's done sees him through all his trials just so he can take that son of a bitch down hard.
** LoveMakesYouEvil
* '''Subverted''':
** 1. The hero makes a stirring speech about how his love will prevail over all, but when it gets to the fight, the villain [[CurbStompBattle beats him handily]]. As the hero lies dying on the floor, the {{Mook}}s lead his love away to be executed.
** 2. An AntiHero dismisses the Power of Love and proceeds to [[DidYouJustPunchOutCthulhu slay the wicked demigod]] with the Power of [[ShapedLikeItself POWER]]
** 3. Unimpressed by the hero's speech about love, the villain responds with a filthy limerick and a whuppin'.
* '''Double Subverted''':
** 1. The hero makes a stirring speech about how his love will prevail, before he is [[TalkToTheFist punched out by the villain]] and left for dead on the floor. The next day, as his love interest is led to her execution, the hero's reincarnation [[BigDamnHeroes charges in, skewers the villain in mid-gloat]], and rides with his love off into the sunset.
** 2.1. However, [[CaptainObvious fighting a demigod is extremely dangerous]]. While he survives, he was so injured in the battle that he can't do anything but wait for the release of death... but is ultimately saved by the WhiteMagicianGirl who worked with him and pined after him in slience. Her AnguishedDeclarationOfLove boosted her HealingHands enough to save him.
** 2.2. ThePowerOfLove doesn't stop him from ''dying'', but it doesn't [[SecondLove stop his love interest from continuing to lead a happy life]] for both of them.
** 3. The hero's love interest is apalled that the villain would say such things in front of a ProperLady (and his callous treatment of her boyfriend), and [[ArmorPiercingSlap bitchslaps him into next week]].
* '''Parodied''':
** "I love you" becomes a [[FunctionalMagic command word]] that creates {{Deus Ex Machina}}e.
** The power of love is used as a ''literal'' power source.
* '''Zig Zagged''': The Power of Love saves the heroes one minute, then fails to save them the next. Then later, love saves them later on when their love is "renewed".
* '''Averted''':
** The hero and his love interest clearly love each other very much, but it does nothing to help them with most of the troubles they face throughout the story.
** No one loves anyone.
* '''Enforced''': We can't just let the hero fail here, but him and his love interest has no sort of weapon or tactic to get them through this. Let's have their love let them make it through.
* '''Lampshaded''': "We can overcome this challenge with the strength of our love."
* '''Invoked''': Something bad happens, so the hero shouts "I LOVE YOU!" at his love interest in the hope that this will save him.
* '''Exploited''': The EvilOverlord kidnaps the hero's love interest so the hero will have no choice but to work for him if he wants her to live.
* '''Defied''': The Evil Overlord [[ArrangedMarriage chooses all marriages]] for minimum possible attraction.
* '''Discussed''': "You know, I wish this was like one of those movies, where our relationship would somehow get us through all these stupid unrelated troubles in life."
* '''Conversed''': "Have you noticed how many shows have the heroes survive because of their love for someone?"
* '''Deconstructed''':
** 1. The hero's adventures are narrated by a psychologist giving a lecture on [[TechnoBabble the chemicals of the brain that cause love, and their effect on a person's physical capabilities]].
** 2. {{Asexual|ity}} (technically aromantic) characters are incapable of tapping into the power (for obvious reasons) and find themselves inferior to those who can have love in their hearts.
** 3. The PowerOfLove [[LoveHurts has a dark side of its own]]. A break-up or an unrequited crush can turn it into a self-destructive force, and make the affected character depressed and/or [[DrivenToSuicide suicidal]]. Then there's the StalkerWithACrush empowered by "love".
** 4. "Love" is an abstract concept. An "ItsAllAboutMe" mentality could potentially make the villain just as powerful as the couple. So could eating his favorite meal ("I love pizza and beer").
* '''Reconstructed''':
** 1. The narrating psychologist falls in love himself and is [[MeasuringTheMarigolds at a complete loss when asked to explain his new-found powers in chemical terms.]]
** 2. {{Asexual|ity}} characters are capable of feeling deep affection and kindness for others such as [[ThickerThanWater family]], [[TrueCompanions friends]] or even [[AllLovingHero everybody in the world]]. Love is NOT only about romance, after all!
** 3. Loving to make people happy, or love for another, is much more powerful than sadism and/or selfishness [[CombinedEnergyAttack because there's more people involved]]. It also has the power [[LoveRedeems to heal others and heal oneself]].
** 4. [[FantasticScience There is a field devoted to studying the power of love]] and it determines that TheFourLoves are more potent than [[{{Narcissist}} Narcissism]] (because it's little more than an inflated ego) or love for food (because it's a shallow and based on wordplay).
