Idols who is heavily associated with certain things/numbers like G-Dragon?
I don't mean like representative emojis or fandom-assigned symbols but an association that is so deeply built into an idol's personal brand and career. The best example I can think of is G-Dragon whose personal brand is heavily associated with 1988, 88, and daisies.
For instance, his peaceminusone symbol is literally a peace sign minus one which shows his name GD and the removed line/petal (if daisy) is at 8 o'clock. His comeback with POWER was released 88 months after his last album in 2017.
Are there any idols who have done this?
