I've seen a few threads on weirdest characters, weirdest NPCs, so here's the logical progression of this trend - what's the most interesting group you've been in or DMed?

I am currently putting together a game with my friends (with me as the DM) and the group is becoming somewhat interesting before we've even begun! We have a monk who's the descendant of a dragon, and could be key to the prophecy bringing about his return. We have an Orc artificer who's obsessed with becoming powerful enough to return to his tribe, who cast him out for being weak, and we have a sentient ooze as his sidekick, who lives in a bucket on the Orcs backpack, and cannot speak (the Orc uses Message to communicate with it).

Add to this I have 2 more characters to come; one is a half-drow chromancy wizard who's backstory is coming soon, and then a completely unknown character which I suspect will be a druid, but don't know anything beyond that!

Either way, it's shaping up to be a memorable group of adventurers!

What's the most notable/weird/interesting party of PC's you've been involved in?

A cowardly monk, A Druid that forgot his spells and a rogue who dedicated himself to bows. We were in a library, fending off hordes of undead, and the monk    ( who had the most hit point) would hit someone with his flurry of blows and quarter staff, and run back to his corner. The rogue was also in said corner just shooting arrows and the only person left in the front lines was our Druid. When your Druid uses his actual weapons, you know there is a problem.

But we still had a great time

For the survival campaign I am running at the minute, I generally allowed anything from any background of nearly-any universe to be placed in to this plane. The reason for being there is related to something dreadful that happened to their character that made them sink to their lowest, in which this plane swallows them right up. Domain of Dread stuff going on here.

1. Goliath tribesman. Original stuff but he is going for the path of the totem warrior except he is going down the wolf path since it relates to his tribe that was massacred when he was away on a hunt. He lost everything and now he is trying to look out for the group of survivors he is now with in this dread woodland. It's a breath of fresh air to see a totem warrior that doesn't just immediately go bear - he was tempted by the other plays OOCly but he didn't see the role-play sense in it. So for that I rewarded for thinking outside of the box and not being generic. He uses a pillar of dark wood as his weapon (in place of a maul) as his weapon, taking inspiration from the Tauren from Warcraft 3. As he levels up he will carve his chosen animals in to that totem and wield it in combat.

2. Human fighter. New player and I generally got him interested because he never played D&D before. He wanted inspiration but knew nothing about D&D, but he played loads of Mount & Blade so I just said to him, "take that world and fantasize it to hell with elves and orcs and whatnot." Which he did and did a real good job of it too. He took a character with an elven companion whom he looks over and hunts for him in her spare downtime; in exchange for this he gave up all ranged weapon proficiency and handed them to her so she can hunt for the party. His noble line was destroyed when the character's arrogance during a banquet caused the death of a nobleman's son which ended his lineage. The nobleman in question had huge amounts of power, stormed the castle in which he lived and completely destroyed his life. So thus he ended up in this world with his companion in tow and only respects fellow warrior types.

3. Tortle druid. This one is essentially a "always on the bright side of life" kind of figure who just wanted to have a bit of fun. Kind of doesn't fit with the spectrum the campaign mood was going for but I let him have it. Not really much to this character except he loves to find all manners of possible narcotics on their journeys. He's a comedic character but it's sort of troubling to find something suitable to mention about his background, which I'm sure will come to fruition further down the line.

4. Aracokra cleric. This is my own DM's character that he introduced in to my campaign and he is still in the progress of figuring out a plausible backstory for him. He was very much taken back when I actually allowed a flying creature in the campaign but as Qui-gon Jinn said "there's always a bigger fish." He has trouble coming to terms with the divine power he receives from his deity (death domain) which was forced upon him when he was child, so now he is trying to come to terms with using their powers that isn't purely made for death. His way of looking at it might make him end up in either spectrum of the alignment charts but since someone gave him a few words of wisdom, he is now settling on being a good-aligned character.

5. Human bard. Lost the love of his life. New player to D&D and never usually had experience with it before and I was genuinely shocked when he threw a lot of potential in my face after I ran the backstory through with him and 1-1 sessions we've had via PM. Used to play for a noble family for a number of years, was one of the most trusted around the place and eventually the nobleman's daughter and he came to love one another. Unfortunately it was very secretive and when the lord found out about it he was exiled, except he didn't go alone. While escaping he took the nobleman's daughter with him for a new life and that was torn to pieces when she fell during one of their escapes from man hunters the lord had sent after them. Very tragic one bar the NPC I talk to him 1-1 with via PMs as well to make him feel better as a character. He was gifted a tiny music box that only plays music to him with a little message that inspires him to keep going.

Since it's one of my first times actually DM'ing I was concerned at first at what I would end up with but I am very happy with this group. I've played with other types in the past in games I've played in, not ran, and they were the very stereotypical kinds of adventures so the characters in them never really rubbed off on me. It might be different since I'm trying my hand as a DM or as a player my characters when I first started were also just generic and randomly rolled up so there was no real connection.

My current party is kinda different, in that we're all "scary" races :D

We have: a Drow Ranger (me), a Half-Orc Paladin and a Dragonborn Rogue

Also, a DM controlled Tabaxi Sorcerer, cause otherwise we're all melee range charas. (our DM said: "if you guys want, I can provide you with an NPC to fill any holes in the party, so don't worry too much about balance")

Our party of a Dwarf Barb, Human Fighter, Genasi Monk and Teifling Druid is interesting.  Anything ground based we rip through like a chainsaw.  Faced a Dragon, flapping all over the place and near TPK.  It was crazy how easy a little aerial mobility crippled us, as up to then we had seriously spanked some high CR monsters.  Dm was amused that now he knows how to cause us grief in a fight.

All half-elf, all bard party for a suspense and intrigue campaign. International super group the Ungrateful Undead (all our character names were based on the founding members of the Grateful Dead, our fans were called UnDeadHeads) by day, international men of mystery by night. Undercover as rock superstars we were actually secret agents in service of our nation.

I played as part of a very interesting party back in high school with a few friends. My character was a polite, soft-spoken, and ineffably good half-elf cleric: a lot like Aziraphale from Good Omens. My friend's character was a drunken, mouthy, and unrepentantly evil dwarf barbarian: luckily, he wasn't usually sober enough to kill anything except what we pointed him at. My brother's character was a very casual and chill half-orc fighter named The Yule Orc, who, like Santa, brought presents to kids on Yule Day. He described the campaign as "like Jesus and Satan fighting it out and I'm just trying to be everybody's friend."
