Hiya!
My strongest character is Julie, the level 10 moon elf rogue. What about you?
Toss up between...
Denakhan the Arch-Mage (1e AD&D; Greyhawk; 20th level Magic-User;
ridiculous amount of time played to get him there...worked it out once; about 3000 hours! O_O).
...or possibly...
Prince Pholtius, Protector of the Faith, Chevalier/Pathfinder of the County of Sunndi (1e again; Greyhawk; half-elf Paladin/Ranger of level 12/11 iirc). In addition to having unbelievable stats, he also had Psionics...to a VERY high degree!
After that,
Sharg Yellowfang (1e again; Greyhawk; 9th level half-ogre fighter),
Grod the Barbarian (1e again Greyhaw-'DungeonWorld' [homebrew 100% underground]-Ravenloft; 7th level human barbarian...NPC now, as he got turned into a Greater Mummy when in Ravenloft),
Dionious Blade (BECMI; Mystara; 14th level "Nature" Cleric), and lastly, another Paladin...
Trinsic Tomato-Head (1e again; Citystate of the Invincible Overlord; human Paladin of, I
think 6th level; and yes, there is a story behind his 'last name'...short version, ate cursed tomato from a-hole Illusionist that gave a permanent illusion of his head being whatever fruit he ate while waiting in the illusionists foyer ...Trinsic chose a tomato ...so his head looks like a giant, ripe, red perfect tomato; he
could have gotten it removed, but he keeps it for recognition and as a reminder of his hubris for being so arrogant/nonchalant when he KNEW he was dealing with a possibly evil Illusionist; think of it as penance/atonement...

).
