This board does not want to focus on canon characters. The character of Nathan Petrelli is not used in role play, he (as well as the leader of the Company) are merely for character profiles, where they will post various information after a character is accepted. If you would like to play as a canon, I urge you to not use a main one, as more than likely, they are dead (Peter is dead, as is Claire). However, minor characters featured in a few episodes (i.e., Candice, Claude, etc.) are allowed.

Again, though, we suggest making your own character. You have more freedom that way.
