So yeah, I gave a quick comment moments ago to the fanon relationship of Darkiplier and Peevils being similar to (any canon version of) Joker and Harley Quinn. The primary difference being that there’d be less of Joker/Harley’s clownish mania, and more of the cold and calculating manipulation that we know and love (to hate?) Dark for. But otherwise, yes, very similar indeed.
Let me explain a bit further.
First, given Dark’s been looking for love since A Date with Markiplier, it only makes sense that he’d eventually find a gal as depraved and malicious as he is, and from there it’d be a match made in Hell.
Also? Given Dark’s weird and obsessive behaviour, it probably won’t be an emotionally healthy relationship. It’d be like the Brooding Boy, Gentle Girl trope… if the brooding boy was the “ALL SHALL LOVE ME AND DESPAIR” demony rip-out-your-heart-and-show-it-to-you-while-you-die type, and the girl is only gentle with him… but she otherwise likes to give a hands-on demonstration of her fine assortment of sharp blades to a captive audience (emphasis on CAPTIVE) when she’s bored/not boinking with her guy.
Yup, when Dark and Evil fall in love… they’ll celebrate their newfound romance by carving out all the blood and screams they can get from the innocent and unsuspecting. Kind of like a When Harry Met Sally: The Unholy, Dear God Please Save Us Edition.
But hey, haven’t you heard? The couple that slays together, stays together.
…I think I feel a fanfic coming on. >.>
