I like to do a silly thing and think of how various characters from various forms of media might play a game of Pathfinder, or some other tabletop game. For my first trick, I'll do Undertale.
Alphys would be the GM, since she'd have memorized every book and be able to snap off the rules in a heartbeat. And while Undyne would be a party member, she wouldn't go easy on her GF, because Undyne's only interested if she's being challenged, so...
Frisk would ask Alphys if the Book of Exalted Deeds was allowed, and then proceed to make a character with the Oath of Poverty and Oath of Non-Violence. This would set them up for that one Prestige Class that can banish the motherhumping Balrog by saying "BAD BOY! GO TO YOUR ROOM!"
Toriel would play a Cleric of Saranrae, taking Fire and Healing, and okay basically she'd play herself, team mom and everything. She would lay the smackdown on anyone with the gall to harm her party.
Papyrus wouldn't really understand what was going on, but he'd probably play a Fighter who was officially hired by the King of the land to go fight bad guys. Alternatively, he might sink a lot of points into social skills and end up being the party's face if Toriel didn't do it.
Undyne would be a righteous Paladin, striking down evil wherever it be! She may murder the dice she rolls, though...
Mettaton would play a glamorous Sorcerer type, possibly Fey-Blooded. If he was a member of the party, he would certainly be the Face. And he would charm EVERYONE!
Asgore might go Druid, actually, considering his green thumb. And may have to heal himself because Tori certainly won't.
Flowey would be THAT GUY. You know that guy. That guy who insists on bringing an evil character to a good party, even though Undyne is sitting right there with her Paladin.
Sans would be there if Pap was there, and would probably play a Wizard or some character that can support his bro. He might even be a Bard, playing Megalovania for the fights.
So, guys, how would other fictional characters play some table top? And what misadventures would all our parties get into?
