This is wrong.
To be more accurate, the characters are more to be representative of cultures. Not necessarily ethnicities.
The original 4 characters, Cabot, Parnell, Abe, and Caira where kind of just generic, so they made them all distinct ethnicities, just to cover all bases.
Cabot was originally White. He was changed to a generalized Asian guy…likely to not play bias toward one culture, which tends to be a toss up between Chinese and Japanese.
Parnell was always Black. As in Black American. That’s what he represents.
Abe is just…Abe.
Caira is I guess supposed to be generalized Latina. Or maybe even Spanish (from Spain.)
Val represents the Scandanavian countries, (though born on Venus. Specifically Poland, despite being named for Valkyries.)
Markov represents Russia (and in the dialogue between Val and Markov, he is Russian by culture, Martian by birth.
M: “How very Russian of you.”
V: “How would you know? You’ve never even been to Russia.”
M: “Mars is a Russian planet.”
Hank represents generalized American. Particularly the more rural or southern regions, based on his accent and general trucker/mechanic vibe. Plus dat barbecue.
Griffin represents Australians & is basically Steve Irwin. Plus sweet beard. Minus the stingrays.
Hyde has a distinct Liverpool accent and thus represents England. Hyde also may allude to Dr. Jekyll…also English (it takes place in London, despite the Scottish author.)
Maggie Lumumba represents African cultures. Particularly Pan-Africa, according to Bucket, though she does not really identify strongly with it. Just casually stating Shona as part of her heritage. The tribal designed tattoos and careful wording of “settlement”, likely alluding to “village” also hint at this.
Lazarus is incredibly Serbian. Oh goodness. Maybe representing Serbia-Croatia.
Bucket was created on Earth and Rank-Rajat alluded to at least a British-Indian background. Rabat is an Indian name. If you know history, India was a British colony before gaining independence. See: Ghandi. Many of Indian decent and those at British-Indian schools have such an accent.
The characters are representative of cultures and ethnicities, though they may not be from said locations on Earth.
This leads to other influences (I chose the most easily recognizable - apologies if they don’t represent everyone) likely down the line:
- German, French, Creole, Québécois (maybe even Canada)
- Irish, Welsh, Scottish
- Portguese, Spanish, Italian
- Native American, Mexícan, (other Latin Americans)
- Carribean & West Indies (though, it looks like our new Support might be influenced…)
- Greek (Mediterranean)
- Egyptian, Arabic, Israeli (Middle Eastern…and try to keep any racism to a low…)
- Chinese, Japanese, Korean
- Hawai’ian, Samoan, Mäori, (other Oceanians)
- (other Nordic countries, maybe a strong Viking stereotype)
- (Southeast Asia? Malaysian, Vietnamese, Thai, Cambodian, etc.)
That’s my two sense.
