What/who was the most interesting character you have seen, heard, played with, ornDM’dnfor?

what made them so interesting?

The characters I play are understanding of their limitations at first level (and other early levels) but they begin the game laying the groundwork for having a very interesting finish in levels 15 and up.  They make contacts among the NPCs, although often more of the background NPCs than the DM usually would like to fool with, in anticipation that when they get to the top there will be many folks that helped them along the way with a piece of information, a potion or piece of equipment.  They are very dedicated to the party's success but they also have their own goals they wish to achieve.  I also play my character sub-optimal to facilitate RP.  For example, with no expectation that he will get an immediate reward, the Bard will buy a round of drinks for the house, or will order an expensive bottle of wine to seal a deal with a toast when in fact the deal has already been sealed.  Playing optimally, I would be saving every copper piece for the special piece of equipment I want next, but playing the way I do makes the RP so much more satisfying, at least for me.

 In Hoard of the Dragon Queen, I am playing a Goliath Barbarian and an Aarocokra Druid. The DM discourages from using too uncommon of races and therefore makes it more difficult for my characters to maintain a low profile.

Here is an interesting one that I may have mentioned elsewhere before: my high elf rogue from ToA. His backstory was that he came from a very fancy and noble, well known family of high elves. When he was the elf equivalient of a teen, he joined the emerald enclave to piss off his dad. What happened next, he wouldn't say, but it is clear the rest of his emerald enclave squad died, and he "didn't technically throw the daggers"

A character I am desperate to use is a dragonborn rouge who is pretending to be a warlock because he thinks it'll make others like him more. He has 8 dexterity, 8 strength and 6 constitution, and has a 19 on charisma. I stacked proficiency and expertise (no idea if that actually makes a difference) into persuasion and performance, which gives him a +8 in both, and he has +6's in intimidation and deceit. The only spells he 'knows' are ones he could fake or pull of with cheap party tricks. Charm person? He has high enough charisma, why not? Minor illusion? Ya boy knows ventriloquism. Expeditious Retreat? Fear will make anyone run really fast away from danger, which is the only time he ever casts this spell (he took the name too literally.) Prestidigitation? It's amazing what a bag full of party poppers and smoke bombs can get for you.

He doesn't actually understand warlocking that much, which is why he can never be in a party with another warlock, (or any other magic user probably), but that won't shake his confidence. He can pull off almost anything by bluffing after all. His only inventory item is a shovel, because he's terrified of combat, and knows he'd die instantly. Occasionally, if his party's got a baddie distracted, he'll use his terrible dex and sneaking scores to run in screaming and smack the monster with said shovel before running away screaming again.

I had to lie about his dex in order to multiclass him so I could figure out how exactly he was faking being a warlock, he actually has 8 dex, but they wouldn't let me multiclass with a roll that low xD Which was about the most in character thing ever.

The most interesting character I ever played was my paladin, Chiemeka des Chapeaux. She was interesting because I got to really explore what it's like when a person of strong convictions and morals has those convictions challenged in a very profound and fundamental way. Can you make a literal deal with the devil and still be a good person? How far are you willing to go to protect your family and loved ones, and is there such a thing as too far? Is it possible for a person to be truly beyond redemption and forgiveness? These were all questions that Chiemeka had to ask herself through the course of the campaign, and it was really compelling stuff. And I think what I liked most about her is that, while she did slip a bit at some points, she never truly fell. By the end of the campaign,  though she was definitely changed by her experiences, she was still a fundamentally good person - even though she'd literally been through hell. She never gave up on her belief that people can be saved and are worth saving, and she was ultimately rewarded for keeping that belief. It was very satisfying.
