Weirdest/Most Creative/Bizarre Characters

Talavan, a changeling House of Cards Warmage raised in the Carnival of the Ravenloft Domains.  Given its background, it had the ability to learn and use any cantrip.

ok, i make some really interesting characters (in my oh so humble opinion), but my favorite one I've played was Thorgon the Ravager, a cloud goliath barbarian (path of the giant). he was feared across the lands, his name silenced taverns upon his mention, and he was nearly a god amongst men. 9 feet tall, 700lb of pure, bulging muscle. in a previous campaign, he had fought the BBEG, a great evil wizard, along with his party. all of his party members died, but not him. no, the wizard had a more humiliating fate for Thorgon. he sapped his power, down to level three, and transformed his head into that of a small call duck (yk, the tiny, super cute/innocent looking ducks).  with this new head, completely disproportionate to his body, Thorgon had learned that he could no longer speak common, or ANY language for that matter. instead, all that came out were quacks and honks. the world soon had heard news that Thorgon the Ravager was slain alongside his party. This, however, did not stop our barbarian. he instead found a new party, one that could help him undo his curse and regain his fame and honor.

soooooo, imagine seeing a 50ft tall, super buff guy with a duck head towering over a forest, letting out a primal quack. i love this idea so much :)

my DM is super lax with characters as long as they are creative, so i somehow made an artillerist artificer with a phylactery :)

so, my character is a birdperson in a steampunk world that outlaws artificers. after going through a gauntlet of trials, i learn the secrets of artificery. i augment my body to do two things:

1. fuse my arcane firearm (in this case an actual gun) into my arm, allow me to use my firearm as a bonus action (according to my DM), allowing 2 spells to be used in a turn.

2. my chest becomes a steampunk coo coo clock. a small, cog work bird pops out of my chest whenever i want. my heart is now in this bird, meaning if I'm scared for my life and at my last resort,   i can send my bird out of me, allowing myself to continue fighting for ass long as my body isn't crushed like a can. however, this has two downside. first, if something hits my bird, I'm probably super dead. second, every hour on the hour, the clock "bongs," or makes a loud noise and exposes my bird heart. this alerts nearby enemies to my location and makes me vulnerable for a brief amount of time. 

please feel free to reply any ideas that you think would make this more interesting!

I'm having way too much fun with this character >:)

I don't exactly know how 'creative' my current character is, but it sure is fun to play. Enter Charles Cheesewheel; a bard with 18 charisma, alcoholism and schizophrenia. This originates from the 'Haunted One' background I forced them to have, which I did write multiple paragraphs of backstory for, but in summary Charles Cheesewheel walked in on a cult ritual, became haunted by disembodied voices and now drinks to dull them. My DM is having a lot of fun giving them mental breakdowns in the middle of crucial scenes.

Well, in my first D&D campaign ever one of the other players had a really fun character. My character was just a grumpy and annoying tiefling druid, but that boy made a genious character. It was, if i am right, a human fighter,  but he was blind. And a lawyer. He literally asked money for helping us out fighting a monster, and when we didn't give him that, he ran outside, switched suits so he would be inrecognisable, took a longsword out of his guide stick and tried to go inside. The door was locked. So while we were trying to fight the doppelganger and my character was unconsious, he spent 2 turns getting inside the building before he actually attacked and also killed the doppelganger. 

We also had a fun thing that if the player would say anything to another player when their characters weren't in the same room. The DM would just simply say: ''Oh? Is that a random tree flying towards you?'' and then the player immediately shuts up. Funnily, the blind lawyer took the oppurtunitly to just say: ''Hmmm.... I smell nature''

That was a good time.

I once had a player who played a 10 year old child turned squirrel. After the second major boss battle against Logan Paul, he got back the amulet that charmed him into a squirrel, and now he can change back and forth at will

Btw Logan Pauls main mechanic was that he would throw lunchy into the players mouths giving them lead poisoning

I DM as much or more than I play, and I think the most interesting and memorable characters have all been NPCs. Often, this just involves taking some bog standard monster and giving in an interesting personality and/or name. One that stands out was a manticore named Maurice that captured the party's sorcerer during the Red hand of Doom campaign. The manticore it turned out was very much just a mercenary. I decided on the Fly to give it that name in an Australian accent. The PCS loved it and wound up hiring Maurice to travel around with them and guard them and help him fight.

Another one was a rogue mind flayer arcanist named Melvin who was generally amoral but interested in learning about human morality and physiology and had a long history of doing very questionable experiments including creating clones and implanting them with false memories to see how they responded and/or to program them to do things that he wanted. He still remains one of the party's main allies in that game, Even though originally he was just intended to be an encounter. 

could i mabyeeee use the warlock one?

I once built a harengon artificer who had a fox steel defender. I was small, so I could use it as a mount. I was literally a rabbit riding a fox. It was insane.

A sturgeon who was captured and imprisoned in an aquarium. After watching countless people perform spells he learned to harness magic by believing it would work if he just got the fin motions right. He infused himself with magical sentience, gained the power of flight, and escaped. He now lives in peace under the name Walter Heisensturg and makes magic powders for customers in a secret lab in the desert.

 Did you actually use that?
