As for music video characters, I have quite enough thoughts in my mind:
We allow characters like the
Crazy Frog and
Gummibär, since both of them are 100% fictional by themselves, live in the fictional worlds portrayed in their music videos, have a solid canon, and provide a plot throughout the music videos.
We also allow characters like
Gluk`oZa. Although she's based on the real-life pop singer of the same (nick)name, the character appears in a fictional world. She also meets aliens who die from a single child's sneeze, and anthropomorphic pigs throughout the music videos. These are fictional elements — such creatures don't exist in our world.
The thing is that even "alive" music videos may have fictional elements. For example, in
this music video we can see that the building bulds iron pillars by itself, and the guy from the band pushes a pretty big boulder to the top. These are fictional elements as well ― there's no bulding that can build iron pillars by itself, nor human who is able to push a pretty big boulder to the top. In
their another music video, that guy has shown some kind of Life Manipulation while singing, which is also impossible for IRL people.
To summarize the legitimacy of the likes of Django Django:
- Plot (Their songs are literally some kind of a plot throughout the music videos)
- Setting (The building from Hail Bop, or simply its ability, is obviously fictional and doesn't exist IRL)
- Canon (Django Django's official music videos are obviously their canon)
An anti-example I can think about is Novislav ─Éaji─ç from the Serbia Strong music video. He's just a man who plays an accordion there, and the music video consists of IRL events only, without any fictional elements. Thus, I think, this way we can draw a line regarding which "alive" music characters may be allowed, and which ones may not.
