The "R8" sign

The R8 sign is what appears at the ending panel of nearly every Johanis Comic, with little but intentional exceptions. It is a smiley face with a slight overlap for it's upper jaw (not a tongue, this is a common mistake), accompanied by the words "R8". R8 originally meant "Rate", as the reader was being asked to rate the comic out of five or ten. The R8 and the face now exist as the trademark symbol for Johanis Comics.

The R8 sometimes also has a "bonus panel", a small tidbit of a character or a small joke. Some characters get a hecka lot of their screen time on this panel, such as the Demogorgon.

While usually appearing as what was just listed, the smiley face has plenty of variations for the type of comic it is in, sometimes not being there at all.

Realistic
The face will appear shaded in with a tongue and teeth, but only in the later comics if I felt like it.

Gradual
Over the course of an abnormally long comic series such as Snowball Fight, the R8 face will become more and more nervous or scared looking as it progresses. It will be absolutely petrified on the second-to-last issue, becoming completely normal again after the finale and resolution.

Demented
After a series of very strange happenings, the R8 face may be rather strange looking. After a typical Patrickia comic, and also the Trevor Wayne ones, the face will become demented, furiously scribbled in, often exiting the boundaries of the panel. It also has other demonic attributes, such as flames and devil horns, or accesorized with objects related to the comic's theme.

Shocked
The face might be surprised after a major spoiler or plot twist, the kinda one to end an issue. It will obviously look rather surprised, and the bonus panel might have a "[suspense]" caption.

Confused
If a comic is abnormally dark or strange, the face will be confused. Usually these comics are made with no plot in mind and don't really have a lot of humor in them. Also, if it simply just tells a semi-realistic story, thats a no-go.

Straight face
Once in a while, the face will just be expressionless. There's not really a reason for this.

Not there
Very rarely, the R8 graphic will not be there. This could be due to space restraints, or if a comic ends with the bad guy dominating, such as in "Stranger Things In a Nutshell 3: Weirdest Object 3." Also, if a bonus panel takes up too much of the square, the face might be ignored.

Odin's battle things
When Odin draws his battle things, he draws me as the R8 symbol, it being my trademark. Can confirm: am not that symbol. He's not even an entity. Just a drawing.
