I haven't encountered much in the way of nutty tragic back-story characters. Especially ones that also run around being ossum possum super people XD Even the aforementioned psychopaths tended to revel in what would otherwise be traumatic histories more than feel sad about it. I have made some characters I wondered if they weren't a little overly dramatic myself, but I at least chose to hope they weren't overdone. In fact, I'm more used to seeing an overabundance on bland, nice guy characters. Where the personality uses common words like "nice, kind, bubbly, friendly" but also "capable of being calm, cool and collected, gets serious in combat" or some rot. History wise, they just talk about how they were normal dudes that passed through life normally (possibly excelling at something combat related if it's relevant to the setting).

And I've never encountered any vampire werewolf characters at all. Probably because I wisely avoid anything titled "Werewolf RP?" or "Vampire RP?" (And yes, I feel like they always have a question mark in their int checks) XD
