Here are the level 2 versions of the pre-generated characters for those who have reached this milestone in the campaign. Even though WotC have not given us any guidelines for the levelling of the pre-generated characters, I have chosen what I thought were good powers for the characters.
The next session all my players will be level two characters and thought I would share them with the rest of the players out there. Don't forget to manually add any magic items you have received. You can do this by downloading the CB files and modifying them with the Character Builder if you have a DDI subscription, or you can even ask a friend who has a subscription to do it for you.

The files are unfortunately a little large and will be reduced in time, but for now it is what it is. Enjoy!
