The parasite in oddworld strangers wrath. What an asshole.
Seemingly every character in the last few rockstar games. They cant seem to not write their characters as being arseholes. Gta v has so far been very unpleasant, cutscenes filled with a bunch of dicks. And not in the good gay way.
I have a long standing hate for Jean Gray. Mainly because every time some action was about to happen in the X Men cartoon she would turn up and be a "I'm Jean Gray and we can talk about this".
