Aradia: uh-RAY-dee-uh (though my friends pronounce the second A like the O in "pot")

Tavros: TAH-vrohs (I split the syllable line between the A and the V rather than between the V and the R)

Sollux: SOH-luhks (There's times where I'll pronounce the O more like an A but not often)

Karkat: I don't really need to give a pronunciation for this one since everybody says it the same lol

Nepeta: nuh-PEH-tuh (I don't trust people who put the stress on the first syllable rather than the second)

Kanaya: kuh-NAI-uh (Definitely the most common one I've seen but I've heard a handful of people say kuh-NAY-uh too)

Terezi: tuh-REH-zee (or teh-REH-zee interchangeably depending on what I'm feelin)

Vriska: Again, this one's obvious enough lol

Equius: EH-kwee-ihs (only real difference I see sometimes is the stress being on the second syllable)

Gamzee: Another very agreed-upon one

Eridan: EH-rih-dehn (or EH-rih-dihn as well, kinda like I do with Terezi)

Feferi: feh-FEH-ree (not a fan of when people pronounce it like "feffery" but it is funny I can't lie lol)

And just cuz I'm bored I'll do the last names too lol

Megido: meh-GEE-doh

Nitram: NIH-trahm (or putting the stress on the second syllable sometimes since it sounds almost identical either way)

Captor: KAP-tihr

Vantas: VAN-tuhs

Leijon: LEY-uhn

Maryam: MAHR-yuhm (kinda like how people pronounce "Mars")

Pyrope: PAI-rohp (pie rope XD)

Zahhak: zuh-HAHK (I know a lot of people say "ZAH-hahk" and I do not understand why tbh)

Makara: muh-KAH-ruh (CV structure so it's pretty simple like how Megido is lol)

Ampora: aam-PO-ruh (ngl this one's really hard to break up into syllables)

Peixes: PEI-shiss (since this is an actual word (Portuguese) I try my best to be accurate)
