What Writing Tips Improve Dave And Karkat Fanfiction Character Voices?

Something that helps me is reading their dialogue out loud. Dave's lines should sound flat, deadpan, with a rhythm that almost trips over itself sometimes. Karkat's lines need volume and speed; you should run out of breath trying to say them all in one go. If it feels smooth and easy, it's probably not Karkat. Another tip: remember their priorities. Dave observes and makes connections he doesn't share. Karkat feels and immediately externalizes every single emotion. A story from Dave's POV should be full of withheld observations and dry internal commentary on what's happening around him. A Karkat POV should feel like being strapped to a runaway train of feelings and opinions.

Don't soften Karkat too much in romantic contexts. He doesn't become sweet; he becomes fiercely, awkwardly protective, and his insults might gain a layer of performed irritation to hide embarrassment. Dave doesn't suddenly become a poet. His affection is shown through actions, like making a perfectly timed shitty joke to defuse Karkat's anxiety, or through reluctant, mumbled admissions when cornered. Their dynamic is grating and specific, not conventionally soft.

So it's all about distinguishing their internal monologues for me. Dave's voice is defensive, a huge part of it is unspoken. He's thinking in puns and meme references, sure, but he's also using that as a wall. The humor isn't just humor, it's deflection. If you write him monologuing honestly about feelings without any of that ironic layer, it feels wrong. Conversely, Karkat's internal voice should be a frantic, ALL-CAPS stream of consciousness even when he's not speaking. His thoughts are just as loud and abrasive as his dialogue, but maybe with moments of startling vulnerability that he'd never voice aloud. The contrast is key; Dave's silence is strategic, Karkat's is a pressure cooker. Their dialogue together is a mismatched rhythm—Dave's slow, deliberate, sometimes painfully awkward pauses versus Karkat's rapid-fire, overlapping tangents. Getting that pacing down makes their interactions sing.

Also, don't forget the setting influences their voices too. A post-canon peaceful scenario would have them both softening, but in different ways. Dave might drop the defensive humor more often, but his speech patterns would still be sparse and precise. Karkat might yell less, but the intensity would translate into passionate, detailed rants about, I dunno, soil pH levels for his fungus garden. The core of their communication is a weird, grating understanding. Dave gets what Karkat means beneath the shouting, and Karkat begrudgingly tolerates the irony because he senses the genuine intent. Capturing that unspoken translation layer is the real trick.

I focus on vocabulary. Dave uses shorter, sharper words, lots of slang and internet culture shorthand that can feel dated if you're not careful—it's a specific era of online irony. Karkat's vocabulary is ironically more 'educated' and melodramatic, pulling from obscure insults and bureaucratic-sounding complaints. He says 'ludicrous' and 'egregious' where Dave would say 'fucked up.' That word choice difference alone builds their voices without needing tons of dialogue tags.

Honestly? A lot of fics get Dave's tone wrong by making him too openly emotive or, weirdly, too mean. He's not a edgelord, he's a dork hiding behind a cool facade. His insults are often affectionate, and his sincere moments are so buried under layers of 'whatever' that they almost disappear. For Karkat, the pitfall is making him one-note angry. His rage is deeply tied to his insecurities and his desperate, failed attempts to be a good leader. His rants should have variety—there's fury, there's anxiety, there's bewildered frustration, and sometimes there's just him being loudly, passionately interested in something dumb. The best fics I've read have Karkat ranting about movie plots with the same fervor he uses for moral outrage.
