Let's talk player classes

No, not the PC classes in your game - the classes that describe the people you play the game with.

Mister Fantastic: Every single number on this player's character sheet has been optimized beyond comprehension to be at least 20% higher than you thought was possible, and it's all legal. Reading one of his sheets will teach you about traits, feats, and rules you never knew existed. Often mumbles cryptic, one-word answers while barely paying attention that end ongoing rules discussions leaving the other players with blank faces. His characters are nearly invincible except for one small key weakness (AC 26 at level 1, but with a CMD of 5). This player can typically one-shot the BBEG and reverse the party's fortunes in a single round. If he's charmed or dominated it will result in a TPK unless dealt with instantly.

The Veteran: A quiet fellow wearing a T-Shirt that says, "Don't tell me about your character: just play." He's never flashy, and seems to do very little, content to let everyone else play and have fun. Always prepared for any situation when no one else is. More likely to aid other players than act directly. He'll only involve himself when everyone else is making a mess out of things, and when he does wake up, his ability to deal with any given situation leaves Mister Fantastic green with envy. Has been known to kill BBEGs via roleplaying. Has the ability to summon natural 20s on demand but rarely uses it. The GM often consults with him on rules issues.

Negative Diplomacy: No matter the class or the character's abilities, whenever this player opens their mouth to talk to someone who isn't in the party, you know the group is going to be in combat to the death in less than three rounds. The GM is uniquely powerless to prevent this from happening. His superpower is always knowing the worst possible in-character thing to say.

Milla Vanilla: Every character this person plays is the exact same thing - even when playing different classes. For whatever reason, this player cannot mentally step into the shoes of their character, and ends up on endless repeat. Often not noticeable until one has played multiple games with this person and notices that their ninja assassin is remarkably similar in temperament to their paladin.

The Conspiracy Theorist: This player is convinced that every single thing that happens is part of some grand tapestry and he is on a mission to figure it out. Often obsesses over small details, makes bizarre (sometimes nonsensical) connections between events, places, and facts. Your worst fear is that he's giving the GM ideas. It's confirmed when some of his wilder predictions come to pass later in the game.

Aaron Justicebringer: The kind of perma-lawful good holy crusader who walks into a tavern and announces, "Greetings! I am Aaron Justicebringer. You may flee if you wish." He's on a mission to smite evil. Since he's always got detect evil running, he finds quite a lot of it and smites often, without concern for trivialities like local customs, ettiquette, roleplaying, and plot. This player always plays crusader types.

Kaboom: Kaboom likes loves lives to set things on fire. Often a wizard or sorcerer, and the kind of fellow who can reduce six enemies to ash in a single round (even if those were six fire elementals). Flaming spells, flaming daggers, flaming hair, and one can track him across Golarion just by following the smoke. Unfortunately, that's all he's good for. Kaboom is a blunt instrument, best kept wrapped in asbestos until the party finds a target he can be aimed at in a location that hasn't got too much potential for collateral damage. This player comes in non-fire flavors too.

Sleepy Pete: Sleepy Pete has a wife, six kids, and a stressful day job. By the time he makes it to the session, he's been clinically dead for two hours already. He'll be asleep within an hour of starting, even faster if food or alcohol is involved. Sleepy Pete is also prone to missing sessions with little forewarning. You're not even sure what his character or personality is because you've been given almost no opportunity to observe him in a conscious state.

Brandon The Builder: A player who in all other ways is relatively normal, Brandon must never be given downtime in any way, shape, or form. With a full set of item crafting feats and flawless mastery of the downtime rules, Brandon will not only rule the entire kingdom in less than six months, he'll find a way to provide every single party member with a Headband of Mental Superiority, Belt of Physical Perfection, two +5 Tomes or Manuals of their choice, and a well staffed keep while doing it.

Broken Billy: This player has no comprehension of the mathematical progression of the games he plays. Instead, he jumps at the first thing he finds that sounds cool. This leaves him with a hodgepodge of abilities that quickly become useless as the game progresses, leaving poor Billy more and more frustrated as the game goes on. Broken Billy steadfastly ignores all advice and all warnings given to him by the GM and more experienced players. Prone to having five first level classes on his fifth level character.

The Novice Namer: Never good at coming up with names, this player has given birth to many legendary heroes: Bob the Barbarian, Robert the Ranger, and who could forget Sheldon the Sorcerer.

The Knife Hoarder: For whatever reason, this player insists on having at least 2 knives on his belt and 4 hidden on his person. He'll never actually use these knives, but as they'd say "just in case."

The 1-Leaf-Clover: This person's dice are trying to kill him. Oh he might roll a natural 20 to get a cheap room at the inn or tell if an item is masterwork (its not), but the second he's in combat, the most you can expect is a 12 or 13.

The iGenie: Only looks away from his laptop when his name is said three times.

The Bookworm: If not taking an action, is found face first in a book looking for a rare never before seen rule that will get him out of the in-game situation. There has got to be rule specifically for negotiating with a different race to reduce the price of a toll. There just has to be!

Secretly Evil: This player almost always plays a Wizard/Sorcerer and takes a Necromantic path. They'll write a sizable and traumatic back-story. Then in game they'll never do or say anything evil in front of the group(in or out of character). In fact, they'll do very little in general. Instead they wait until everyone is gone and tell the DM what evil things they actually did while "no one was looking".

You should try FATAL: Makes all their characters and every encounter somehow revolve around sex.

Spellsaver: Spellcaster that never casts their spells because they think the next fight is going to be harder.

The Lore Keeper: This player may not be the most talkative person at the table, but that's possibly because they're too busy writing down every even happening in the game. Conversations, shared loot, timelines, and character sketches -- this player is devoted to the story, and keeps track of all of it.
