I often have atleast a couple backups for my characters, in case the current character dies horribly (almost happened last game session, damn disintigrating traps), or if I find the character just is not pulling their weight and not that enjoyable, depending ont he DM.
It also is a thing where I like to draw my characters.  And well, eventually, I want to draw soemthing else, get into going into the character's background and thinking "That's be a cool character" and all that jazz.
Right now, I have the following backups:
Game 1
- Current Character:  Druid avener hunter killer sort of loony.
- Backup One:  Kobold artificer with hommunculli managery, magic shop, and followers.
- Backup Two:  Dread necromancer with warmage bodyguard, and horde of undead minions.
Game 2
- Current Character:  Kalashtar psychic warrior ass-kicker.  I'm not too worried of him dying though.  Still, just in case...
- Backup One:  Half-daelkyr ranger/impure prince, for ickiness
But yeah.  Half of the time its just so I can draw something neat, admitedly.  Still fun to do
In games other hten D&D, it also helps if you end up having to run a game.  A few of my backup PCs in Exalted games have found their way as NPCs in games I've run.
Ummm, and stuff
