This is my interpretation of the average rule 34 hater. These users will go on the internet and look at explicit material of their favorite characters only to leave a comment saying to go "kill yourself" or "what the fuck is wrong with you" and things like that.

The head is represented as a computer monitor, the screen indicates "No Rule 34", the TIU on the chest stands for "Toxic Internet User", and the green background represents toxicity.
