I like the light and dark glowy orbs from the game screenshot. That's pretty much as close as its possible to get to showing the entire trope in one image.
I find the dragon pretty terrible, actually. Not only does being half black and half white imply something more like Fashionable Asymmetry than a combination of opposing powers, it's also just aesthetically pretty ugly.
The literal Yin Yang Bomb is decent though, if we don't like the game screenshot.
I still say that Light And Darkness Dragon fulfills that same niche (wing dichotomy), but does it a little better than Lucemon, because Lucemon's uniformly black coat sort of throws off the visual dichotomy a bit, while the Dragon's scale colors are split between black and white right down the middle.
they're both good, and for mainly the same reasons, but I just favor the Dragon a little bit more because of that.
I have a message from another time...

Possibly. It certainly goes the same route as the Arc Rise Fantasia thing.
Still think I prefer the Dragon.
I have a message from another time...And I would like to note that, while the cherry bomb image is a good visual pun, it could easily confuse readers into thinking that the trope is about an actual bomb.
Not really I think people will get the trope easily enough and an actual Yin-Yang Bomb is still very much covered by the trope. Its probably the best option IMO.
Sparkling and glittering! Jan-Ken-Pon!Always have to straddle the line between Viewers Are Morons and Viewers Are Geniuses.
Diagonalizing The Matrix
... Five hours isn't near enough for a bump.
An Ear Worm is like a Rickroll: It is never going to give you up.
I would post a picture of its attack, but the manga decided to make its Breath Weapon look like light, with the dark element kind of hard to see.
