Sometimes a comic artist will give a speech bubble a unique appearance. It could be shaped differently, colored differently, or have an unusual font. Sometimes this happens to a normal character temporarily to indicate that something unusual has happened to him. Other times, a character has a unique Strange Speech Bubble all their own to show that they have an unusual voice or are just plain weird. Mostly a Comic Book, Manga, and Webcomic trope, of course. Examples Manga
- Fran from Franken Fran.
- The Last Days of FOXHOUND: Mantis' speech bubbles change from black text on green to green text on black when he uses mind control.
