The character the party must seek for wisdom.

You're gonna drive me c r a z y;
You're gonna drive me m a d;

gifter like delibird in pokemon

that one character in your party that betrays the rest of the group for power and then gets defeated by your party later on in the game

hidden boss of good that later joins party
RAWR post more you! xD

She's that one character that you'd believe to be useless and whiny, but proves to have some merit to the party's success.

Hero!
<3

Leader of the crime syndicate your group gets all its supplies from.

I would say one of the last bosses you have to defeat.

The little brother of the hero who gets tragically killed by the forces of evil and strengthen's the hero's resolve to triumph.

the evil villain!!

You seem like one of those early villains the hero faces that says things like "If you'd only look at the big picture, you'd see that we're doing this for the good of mankind!" and other such stuff.

part of the team that works for good
as a spell caster

You're an assassin for the chaotic neutral group in the game.
