What type of character would you be in a movie/show/book?

I would be that one character who appeared a total of three times in the entire show and was always dubbed by someone else and is absolutely smothered by the entire fandom (with the plot twist that in the big climax it turns out that he knows the answers to all the questions of the universe.)

Or just some random crow.

Me want be assassin with high dex stat

But I'll prolly only get to be Mob A instead

The side character who is a friend of the main character but is the first to die by doing something extremely dumb and stupid.

Either the masked monster who warns the protagonist or the theatrical Dark Lord.
