Not sure if you'd like this, but it is pretty much straight forward, no spellcasting.
Human Barbarian 1/Warblade 5/Fighter 6/Disciple of Dispater 8
Troublesome negative part:
* Doesn't use a two-handed weapon, uses two-weapon fighting
* Saves are pretty good EXCEPT Will saves, could be a problem for your party if your get dominated, but hopefully you'll just Iron Heart Surge that away
Counter to negative is:
* Gets nigh infinite attacks
* Has an interesting "I'm counting coup" effect that lets you charge up to your opponent and basically slap him silly for no damage with a huge number (again, nigh infinite) of touch attacks, makes your opponent get angry at you, and next round, you hit him once for +5 x (# of successful touch attacks last round) damage
* Gets the ability to effect themselves with Ironskin (essentially Stoneskin as per a 15th level caster) once per day (giving you that "defense other than ac" effect you wanted)), also helps with the above "counting coup" to prevent yourself from getting pwned by your enemies after you charged up and slapped them a thousand times for no damage, heh
* Touch AC gets pretty darn high

Note: the above spoiler shows what the character would be like if I built him up to level 20, along with what magic items I would give him. Your choices may differ.
It is important to note that you gain back all of your maneuvers with Warblade by taking 1 round to either do nothing or do a SINGLE ATTACK. Perfect for the round immediately after "counting coup". You probably only need 1 attack because as long as you don't roll a one and you hit your opponent you counted "coup" against the round before, he'll die from the massive damage you add to your 1d4 Kukri.
