I think common Tropes in my characters are [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/CreepyGood]Creepy Good[/url] or [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/DarkIsNotEvil]Dark is not evil[/url] and no this not just my O.C where talking about seriously i mean it, if i am going to play in a crossover i usually pick a character that has this trope or some variation of this (A few Examples Jacket(Hotline Miami), Faust(Guilty Gear) and Chris Walker(Outlast) i usually play a character who is affected by these two tropes

For some other tropes that seem to crop up a lot whenever i play
Adorkable 
Functioning addict 
Bad Powers, Good People
Silent Bob/Selective Mute (Yes i tend to play characters that can't communicate in a medium where interaction is key (I am a fucking idiot)
Dem Bones
Monster Adventurers
