Slicker than an oil spill.
One thing I've picked up on lately is how much the Japanese really seem to like that greasy, 50s-era slicked back hairstyle look. While I can't exactly speak from much authority of their culture, I would have to imagine it's widely regarded as a ''cool'' hairstyle over there, right along with smoking, and leaning against a wall with your arms folded and your eyes closed whilst explaining some important plot point... Probably has something to do with its history regarding samurai at that. Though over in the west it's more associated with Italian-American dirtbags, mobsters and all around nefarious folk.
In any case, I decided to create a list noting how much of that damned hairstyle has crept into our videya games. Though while I made a mention of the Japanese, I want this list to be all inclusive and accepting to anyone who's gone and combed back their noggin!
I will also of course gladly appreciate any contributions to help expand this list some as well. However I should note that I'm referring to pre-determined characters, so the user-created characters that may have the option to pour grease over their hair won't count.
