All right... I started off just counting them off of the save manager on OBMM, but then I had to add a bit of detail, because I just have this compulsion to blather on about my characters, so, in chronological order:
1. Bob - Breton male, Jack of all trades. My first character - overleveled, did everything, no personality.
2. Jean - Redguard male, sword and board. Erratic and violent, went to the Shivering Isles and never left.
3. Claudia - Redguard female, stealth war axe fighter. My first female character - happy and enthusiastic, short attention span, genuinely loves people. Uses the Innocent voice set.
4. Tim - Breton male, destruction mage. Superhumanly powerful pure mage - nothing and no one in Cyrodiil can even come close to challenging him. Mostly retired to the AU.
5. Kyla - Dunmer female, claymore/heavy armor fighter. Retconned to be Dave's younger sister. The destruction of their family and home left her determined to uphold justice and protect the weak. She's noble, brave, kind and a bit sad. I respect her more than any other character I've ever played.
6. Bogmok gro-Lob - Orc male, pure mage. Woefully insecure and morose, mediocre skills, mostly retired.
7. Clive - Imperial male, mage/assassin. Thoroughly vile and despicable - arrogant, cowardly and cruel.
8. Dave - Dunmer male vampire, shortsword assassin. Kyla's older brother - the destruction of their family and home left him bitter, and he became very ruthless and very deadly.
9. Mindi - Bosmer female, battleaxe fighter. An intense ball of energy - alternately friendly and brutal. Probably not entirely sane. Uses Imoen's voice set.
10. Hale - Nord male. Warhammer fighter. Literally dumb as a post. Can't use magic, doesn't sneak, just blunders along until something hurts him, then he hits it until it stops, then he rests until he feels better.
11. Vorlin - Bosmer male, bow and axe hunter. Fearful loner, only comfortable in the wilderness. Doesn't do quests at all - doesn't even talk to people more than is necessary to sell the hides he collects and potions he brews.
12. Lydia - Breton female, sword and board. Charming and upbeat pale ginger. Used a bit of magic early in her career but always wanted to be a pure swordfighter. Never got very strong, but did get VERY skilled with the blade. Mostly retired and living in Cheydinhal.
13. Maelyn - Dunmer female, pure mage. A retired courtesan, fabulously wealthy, sultry, seductive and very powerful. And mute - not just in the sense that all player characters are, but literally mute - cannot, or at least does not, speak.
14. Tina - Imperial female, sword and board. Erratic personality with an overdeveloped sense of duty, torn between the desire to escape her bad decisions and the need to carry through on her commitments. Lost, lonely, sad, fascinating.
15. Sees-Two-Fish - Argonian male, dagger fighter. Carries a set of enchanted daggers and swaps between them depending on the situation, so plays sort of like an on-touch mage except that he delivers "spells" with daggers instead of his hands. Refuses to wear armor (or much for clothes for that matter). Probably not sane.
16. Jana - Nord female, destruction/mace battlemage/paladin. As close as a human can get to a goddess - very proud and very powerful.
17. Z'ren - Khajiit male, stealth melee. A pure sneak fighter - dual wields (to the degree that Oblivion allows) short swords and won't fight any other way. Doesn't care for armor much but isn't a purist about it.
18. Jeff - Breton male, pure pacifist. Pretty much unplayable, since he's a true pacifist. He not only can't kill, but can't even do anything that could lead to someone or something being killed, so he can't even leave the IC. If it was Earth instead of Nirn, he'd smoke a lot of pot and go to drum circles.
19. Lorl gra-Ornug - Orc female, battlemage. Surprisingly sweet and friendly for an Orc - is actually VERY intelligent and has cultivated that image.
20. Jibran - Redguard male, claymore swordfighter. Fiercely proud - refuses to wear armor because he believes that that would imply that he doesn't trust his blade skills. Very fast, very agile, very skilled, very deadly.
21. Henry - Dunmer male, stealth hand-to-hander. Very monk-like. My long-time avatar on the Bethsoft forums.
22. Lud gro-Dalum - Orc male, ex-adventurer turned thief - bow and mace. Scruffy and disreputable and a bit of a social climber, but not a bad sort really.
23. Arlowe Clanler - Imperial male - entirely random character - everything done with dice rolls. Middle aged petty thief and arena gambler.
24. Hanna - Little Elf female. Archer, conjurer (mostly animals) and a bit of blade. Quiet and stand-offish - just doesn't seem to like people much.
25. Cressida - Little Elf female, claymore/bow fighter. Cool and aloof golden-skinned blonde. Very competent, serious and self-contained.
26. Rydri - Redguard female, spellsword. Sweet but a bit rough around the edges. For some reason, is a target for bears (she was even attacked by one in the lobby of the Tiber Septim).
27. Dawn - Breton female, battlemage with a claymore. Spoiled "princess" - self-centered and difficult, but a decent person all in all.
28. Lemdel - Altmer barbarian - battle axe and bow. Disdains magic and prides himself on his physical strength. And his skill with women.
29. Dun - Imperial male, longsword fighter. Good natured, somewhat seedy, surprisingly competent when he wants to be. Travels with a female Bosmer archer named Sara who tries to keep him in line.
30. Ughoth gro-Sharam - Orc male, pure mage. Haughty, arrogant, very practical, very determined, very powerful.
31. C'mala - Khajiit female, sort of a stealth spellsword - mostly Illusion and a war axe. Quiet and intense - don't know much about her yet.
32. Mu-teel - Argonian female, bow, sword and destruction fighter. Kind to her friends - ruthless to her enemies. Just very straightforward and very efficient.
33. Belladonna - Little Elf female, illusionist/archer. Fiery redhead glass cannon. Uses the Annah voice set.
34. Elenin - Altmer female, I don't know yet. She looks so sad that it breaks my heart, but I have no real idea who she is yet. Included just because I know I'm going to play her.
So... 34.
