Do your characters have any catch phrases? Intentional ones or things that they just happened to say over and over again?

Haha, no. But one of my friends has the catch phrase "Dear GOD!" (say it in a high tenor-ish sort of voice for full effect.)

Nope. Catch-phrases tend to work better in a comical story, and mine's more of a drama.

My main character does tend to say "Well..." a lot, but that's less of a catch-phrase and more of a common speech-pattern.

My character Cc will prolly say "hehe, Die" more often. It was quite popular the first time...

Sally has one where she says "Oh fluff." when something bad occurs.

She's only said it like twice in all my near 200 pages though so I'm not sure if you can count it as a catch phrase =p

Not really "catch phrases" but some repeating speech patterns. Like Yuki almost never uses "real" curse words. When in dire peril, she tends to utter a mellow "Crap." In less dire peril (usually an accident that was her fault), she says "Darn it."

Also do nicknames count? My characters each have several nicknames depending on who is addressing them.

I try to be conscious of each individual character's "voice", i.e. certain speech habits like the fact that Vector always talks like someone out of an 80s army movie, but I think if I went as far as assigning catchphrases, it would come out awkward. This probably works for other people, but not for me. Well, unless the fact that Shyft says "f*ck" a lot counts. Teehee.

No one in my comic has really had a "catch phrase". Some of them have had limited vocabularies in cases and tend to repeat a lot of phrases. Maybe Izz's "Okay" counts, since she basically just says it whenever she doesn't quite understand something or otherwise feels a line of discussion is over, which happens a lot.

I guess speech patterns should really count under this subject. Character tend to have certain ways of speaking more often than particular catch phrases.

...though Kate tends to say "Holy Hecate" when surprised.

Due East's characters don't specifically have any catch phrases. Each character has a unique personality and way of saying things, though.

I did have Phira/Chance use "spit and bother!" in Off Hours once, but I don't think I'll have her make a habit of it...

Sun of Rival Angels has been prone to saying 'you got ninja'd' after she clobbers you from behind.

XD

I'm not especially surprised that few people use catch phrases in their comics. Catch phrases work much better when you can actually hear them, and tend to just come across as cheesy when they're read. Sort of like how some dialogue that seems fine when you read it sounds really dorky when somebody says it out loud. Sin City is a good example of that.
