Definition
In a normal RPG, right now you'd be rolling dice to determine stats, or deciding how to spend some "character points."  But that's not the way it works in OPKRPG.  Right now, you're going to decide--nay, you'll know, who you are acting.  There's many ways to define yourself, or find out.  Pick one of these.  Or don't; you can do whatever, as long as you know whomever.  Experienced roleplayers take note: the character sheet is the definition part, with your descriptions of past and present.  The statistic sheet is the one with things like strength, health, intellegence, etc; just so there's no confusion with the terms.

No matter which method you use, make sure to include: 1) At least a passing physical description-so when you're all roleplaying, the other players have an idea who they're talking to; 2) Some note on how s/he acts, on such things like Pokémon, fighting, and anything major/of note; and 3) something on their history.  I mean, if you don't know where you were, how can you figure out where you're going?  These three points are the basis for all the following methods of definition.

The simplest (and fastest) way is to just take a few, sketchy, notes on their appearance and mannerisms.  While the level of inexactness is bothersome to some, others say it's freedom: freedom from those who would interrupt you when you're RPing, point to your character sheet and say "But that's not what you said here!"

If writing stories is something you do well, you could write a story of your past.  Since it's going to define who you are, and not the other players, only use characters like your family members, so you don't create mixed pasts or anger the others.  Usually, a background story that has no plot, and/or no affect on the "present day," is not only pointless but often acts as a poor character sheet.

Another way to begin definitions is to draw your character.  Some people, when drawing, have some great ideas and observations about the characters they're drawing.  Just make sure to copy those great ideas down onto paper, huh?  Drawing has the added benefit of giving a concrete source for the other players' minds' eye.

Alright, did you find out who you're going to be?  If you don't, s
