Mostly for variety. The wiki's about a long-running rhythm game and the main characters get a new look with each game, so I had them next to the logo in their various designs. So the logo itself is actually consistent, only the main characters' designs changed.

Like this one has them from the first game, this one is from the 9th, the 16th game, 24th game, etc.
