Okay, you consider it a cheat answer, that’s fair. But, just for the record, pokemon is a fantasy series. And the pokemon are a race of monsters.
But for a more typical answer, I’d go with either dragons cause they’re usually powerful and intelligent and can fly or warcraft’s taurens cause they’re like a hippie version of a minotaur. Strong and intelligent but with an affinity for nature. A tauren druid being a very fun combo with tons of versatility.
No, the joke wouldn’t have been as funny if it said “scammer” instead of “smart engineer”. Plus, I think it’s more a jab at engineers rather than anything. Because most would rather argue/explain the whole 10 vs 11 thing than just go "ok, sure, I can do that " and get paid.
