Okay, the user wants me to translate "black panther" into Japanese. Let me think about the correct term. The Black Panther is a well-known movie, so I should use the official Japanese title. I remember that it's called "ブラックパンサー" in Japanese. Let me double-check to make sure there's no alternative translation. Yeah, that's the standard one. Since the original content is in English, I need to translate it. The user also mentioned that if the content is already in Japanese, I should leave it as is. But in this case, it's English, so translation is needed. I'll just output "ブラックパンサー" without any explanation.
