It's a nickname, not a name. The character, in appearance, role and demeanor, is Dawur.

However, the name "Dawur" makes no sense from a story-telling point of view - his leader is called the Negotiator, and here "the Ambassador". They also have "the Scientist". It'd make more sense if he had a descriptive title, like "the General", "the Commander" or "the Enforcer" or something. Not "Dawur".

And when Cassie spots something that resembles Blue Beetle, but darker blue, calling him "Black Beetle" isn't much of a stretch. She wouldn't call him "Dawur". He doesn't seem like the type to introduce himself, and the Ambassador has no need to name him.

His nickname is Black Beetle, but it's more of a shoutout to the villain from the comics than that it actually IS the villain from the comics.
