As someone who always likes to play the party contrarian, the key is to be the butt of a joke once in a while. Everyone hates an edgelord who is both insufferable in character, and also goes out of his way to be disruptive to the GM and the campaign. But if your goal is play as Shadow the Hedgehog straight because it's funny how hard you clash thematically with the others, you'll quickly become the table's favorite.

You don't have to be quirky either to pull it off, being exceptionally merciless, motivated entirely by money, using weapons or tactics that cause as much collateral and unnecessary damage as possible, or believing in outlandishly wrong ideals like total Conquest of everyone who isn't you, are all incredibly evil acts, but become funnier if the baseline is genuine acts of good. For an example, look to the Skeksis from the Dark Crystal. These bird people are so irredeemably evil in every possible way, it loops around to being funny compared to the Gelflings of the world, you may even end up rooting for them, just to see what other heinous, unforgiveable act they'll commit next.

>TLDR: CE only works if the party is majority good to give you a springboard to work from
