Your main just started playing D&D
What kind of character do they play, what kind of campaign are the playing, who are they playing with, and who's the GM?
Be creative!
plays an inspector-ish warlock skilled in swordsmanship, poking fun at Caitlyn's more proper manner (as opposed to her... "punch first" approach). Sherlock instead of Watson, ya know? There's an evil guy, and as far as Vi's concerned she just needs to be pointed in the right direction... while driving Caitlyn and Jayce insane along the way.
Obviously Ekko is the GM, always rewinding time to prevent TPK's. Playing would be way too easy.
Plays a rouge, steals everything in sight, then runs off to the next town
Plays as the unexpected hero, the Burglar, oh wait that's already a story....
Plays as the seductress, that steals the souls of men and/or turns them into pigs....nvm....
Plays as if she's on the side of the hero, but betrays the hero, in a way so emotional distraught for the hero that he can't return to the quest the same anymore, and takes all the power and glory and gold. Don't forget the gold.
Before the betrayal she becomes the best friend and ally to everyone on the quest, stealing little things here and there along the way, the team thinks she's the best ally ever. until she reveals she's the one they should've been after the entire time. She lures the good guys into a trap of her making, making them stray from the correct paths, fools them into doing mundane quests that get them almost nothing, then continues to thwart them as they try to figure out who's causing all the mayhem until she reveals herself as the true villain, and laughs at their pathetic attempts to outwit her on the entire journey, but chuckles every-time they fail, since this is all her doing as she is the DM. MUAHAHAHAHAHAHAHAHAHAHA.
plays as the stereotypical healer, but with a bonus, she's the unknown princess chosen by DM 
, as they continue on with there adventures to the Mystical Poro Kingdom. 
plays with the Demacian crowd. Tired of being stereotyped as 'the Lawful Good paladin' (which she played in the last three adventures) she's decided to make her new character a tyrannical Lawful Evil cleric with dreams of taking over the world, explaining to the surprised group that she'd like to 'play myself as Morgana sees me.' A shameless powerbuilder who seems able to do everything, the other Demacians' goodly PCs are willing to put up with her character because she's the only one enabling them to survive the repeated dragon attacks sent by novice DM Shyvana.
Plays a bard with a CHA of 18, a maxed Diplomacy skill, and ridiculously lucky rolls so she manages to talk her way out of everything despite the fact that the rest of the party, except for their fighter (
He signs up as "Lawful good wood elf" and uses a bow that shoots bananas
is the GM. Chaos ensues.
plays a knight trained to use a tower shield, not exactly pleased with the lack of ability to manipulate metal specifically, combined with the convoluted difficulty in trying to play a necromancer (why can't he just control a dead enemy whenever he wants like he always does). He plans on getting more into the game to homebrew things, so he has to do less roleplaying, and grumbles whenever Vi's warlock pokes his knight with her sword.
Ranger: That one ranged character that decides, "You know what, FUCK THIS!! I'M THE FRONTLINE NOW!!" and proceeds to go with her bird and manage to scrape out a few kills before dieing. RIP Quinn, 2013, Doomed since release.
joins the party as a ranger, but literally walks to the front line, next to the fighter and paladin, so he can show off. He is very skilled, but due to his arrogance he often tries to get into the middle of the enemy (even though everyone constantly reminds him he didn't go dual-wielding blade ranger, he went ranged ranger, so he should STAY BACK). Constantly gets the crap beaten out of him, to the point where the cleric 
literally just follows him around and heals him, so he doesn't die. He then proceeds to complain to the GM how the enemies are too weak and should be made stronger to suit his "amazing skills". Oh, and he always insists that he is the best in the group and should be getting paid the most for all these missions (the GM is 
, and he doesn't really care, so he just kinda says, "yeah, that's great, see me afterwards" and then rushes out of there the moment the group decides to wrap up the game) By the way, here's what the party looks like:
Paladin
Barbarian
Druid
Wizard/Warlock
is playing a Fighter/rogue multiclass charged with bodyguarding the paladin 
by the Solari and Rakkor. Not that she needs it as every encounter proves. They are followed by 
, a Rogue/cleric who is obsessed with ending the Solari reign but finds herself helping the duo from the shadows, excusing herself with the belief that it must be her that defeats the suns messiah.
. At first 
the sorceress, a determined mermaid on pilgrimage to save her people. 
The Scholar
The Marauder
The Bound
And
The Conqueror
, hired by Noxus to track and kill the group before retrieving the artifact.
plays a half-elf fighter and is very strategic at things and doesnt go in alone when it seems he will lose, he travels with 
a monk
"Look...the Gunslinger rules are right there and there are no rules saying I can't be a Dread Pirate prestige class from it!"
would quit playing once she found that she couldn't play dragons and that she could only kill them.
: "Why is this table so tall?! I can't see the board!"
plays a big, strapping knight ala: 
Thief/Rogue
Thief/Wizard
Warlock
Warlock
