But that's the problem and it could go right into the "tropes I hate"-thread: Japanese mangaka choosing English or German names, because they find them "cool", without having a basic understanding of the language. Case in point: If you want to use "Crawler", okay. THen leave it at "Crawler". Always calling him "The crawler" just sounds like shit and is cringe to the max. Imagine saying "Hey, it's the superman" or "hey, it's the batman!" every fucking time. Ugh. And while no examples come to mind, circumstances like that happen in anime all the time. I'm okay with the usage of foreign words, but pls make sure they fit in well.
"She's the only non-loli girl in the show, your honor!" will be my defense in court
