'''Basic Trope''': Opposite powers combine for massive damage.
* '''Straight''': [[EvilOverlord Emperor]] [[DarkIsEvil Evulz]] and [[CorruptChurch Bardiel]] [[LightIsNotGood Solaris]] find their powers of [[CastingAShadow Darkness]] and [[LightTheWay Light]] to be stronger combined.
* '''Exaggerated''': They [[FusionDance become one being]] capable of handling both elements [[GameBreaker without any drawbacks]].
* '''Downplayed''':
** TheRedMage can use both dark and light magic [[MasterOfNone but can wield neither as well as a specialist]].
** Combining the powers creates a different element with the best and worst of both worlds or its own unique properties (e.g. combining [[ShockandAwe lightning]] with [[PlayingWithFire fire]] creates a [[EnergyWeapon laser]] that hits its target instantly and penetrates targets but doesn't set them on fire nor does it arc to other targets).
* '''Justified''': The powers work on the basis of ElementalRockPaperScissors, so a Rock/Scissor combined attack will be powerful against ''anything''.
* '''Inverted''': Evulz's and Solaris's powers cancel each other out.
* '''Subverted''': Evulz and Solaris are forced into an EnemyMine situation. They both use their powers at once, there's an almighty flash of light... and no other effect, except that they both now seem to be {{Depower}}ed.
* '''Double Subverted''': ...but they soon realise the effect of working together was to release the SealedGoodInACan with ThePowerOfFriendship. D'awww.
* '''Parodied''': [[KillItWithWater Aquaboy]] and [[KillItWithFire Pyrogirl]] attempt to combine their powers.
* '''Zig Zagged''': Attempting to combine the powers of [[PowerOfTheVoid Null]] and [[PowerOfTheSun Sol]] creates wild magic that's inconsistent at best, ranging from an InfinityPlusOneElement to a small, embarrassing "phut" as the elements cancel each other out.
* '''Averted''': The powers don't work any differently together than separately.
* '''Enforced''': The writers want AnAesop of the importance of working together.
* '''Lampshaded''': "Oh no! He can use light and darkness magic at the same time- run for your lives!"
* '''Invoked''': "WeCanRuleTogether! With your power over the Light and my power over the Dark, we would be unstoppable..."
* '''Exploited''': Emperor Evulz is using this power as a means to [[TheCorrupter turn Bardiel to his side.]]
* '''Defied''': Bardiel's [[DarkIsEvil black]] and [[LightIsGood white]] mentality prevents him from ever accepting that the two could be used together.
* '''Discussed''': ???
* '''Conversed''': ???
* '''Deconstructed''': Due to BadPowersBadPeople, putting together a matched [=Light/Dark=] team that is capable of working together - let alone agreeing on a common goal - is so difficult as to make the benefits not worth the effort.
* '''Reconstructed''': When a super-powerful OutsideContextProblem shows up, they're able to beat it together, and they realise that it's appropriate that such great power is reserved for times when it's really necessary.
