Barbarian or Vivisectionist Alchemist. Barbarian would be the better actual combatant, but the Alchemist is more in line flavor wise due to its Mutagen ability. It also has a variety of other buffs that all come in liquid format. The Vivisectionist archetype would replace the bombs as those aren't quite fitting with the theme and give you sneak attack instead. Sorry that's rather brief, but I'm tired and sleep calls.
I'd go for Brawler, or possibly Tetori Monk.
Brawler fits, as Bane wasn't exactly the most graceful fighter. Feat-wise you would need to get at least some of the grapple feats of the Tetori monk, as Bane breaking Batman's back is just too awesome not to try and replicate. Martial Flexibility allows you to swap combat feats around meaning you can play-up his extreme brawn or make some other choices when you want.
I would possibly even consider Mutagenic Mauler archetype to highten the freak of nature which is Bane, though giving-up Martial Flexibility is not great. The Beastmorph ability does allow you to get darkvision and such at some point for the whole "born into darkness" theme, though maybe I'd go Brawler and just dip one level fighter for feat and Mutagen.
I'd actually advise against Barbarian, as Bane is rather calculated and I do not dig rage for Bane too much. Though Come and get me would be nifty on a Bane-type character, provoking enemies to hit him and then retaliating with brute force.
Well that depends a lot on what it's class is. So if you've decided that then we can move on to the next question.
You probably want the Dex higher, as that is his AC, if you don't care about him getting hit then I guess it's okay. Also raise his wisdom, that's really low and open for being mind-controlled easily.
The con doesn't have to be that high, dropping it 2 or 4 points to free up points elsewhere isn't a bad idea.
Why is his Cha a 12 and his int a 13? I'm not seeing the reasons for this.
Charisma doesn't do anything if you're not intimidating.
Brawlers don't need the Int 13 for combat feats.
So Unless there are some other reasons you're good to drop these. If there are reasons please share them.
Also personally I love the mutagenic mauler archetype. I like it because it gives it a damage and to-hit boost that it normally doesn't have. You can also combo it with the steelbreaker too if you wanted.
I am trying to as best as possible ((efficient or not)) make bane as a character here in pathfinder. that's why I have the weird stats of Cha and Int. Note I am more going for the New bane not the older one or I would go alchemist. and mutagenic brawler
I Think the Mutagenic Mauler brawler archtype is a good fit. That Way he Can ad some juice when he need to do that little extra. It Will also add to his inhumanity. I dont find dumping dex and Wisdom very Bane like i would Think at least 12 in both and most likely 14 in dex but bane is not a 15 point so you May have to cut a toe. Personally i would take somthing like versatile human 16 str, 14 con 12 in rest on a 15 point buy. And then Throw stat increases in str all the Way. Other weakness i would fix with items. Is this a PC or a NPC villain?
Edit: new bane is the gentleman from the Batman movie? The i would go monk he is hanging out with the ra as gul crew. Or since it is in a World of magic the sacred Fist warpriest pehaps or at least qigong monk.
It is my PC for wrath
Sacred Fist warpriest then 16 str, 14 wis, rest 12 versatile human. Pummeling style and charge at 12. You Will have magic yes but the movie bane have narrative power, and need it to be him, in a Way a brawler cannot get.
Bane screams Mutagenic Mauler. Pretty sure the archtype was made for this.
You also retain Brawler's Cunning with that archtype, which allows you to tank INT for practical reasons. I realise it doesn't fit Bane but mechanically there is no disadvantage having an INT 7 if you really had to (not recommended). But if you find yourself tight on points it is an option.
never looked at a war priest how would this one look at lvl 11? build wise
If you start with the numbers i gave you. You put in feats like weapon focus untmed, power attack and power attack and pummeling style at level 6 . Take Fates favored trait. And you are set to go. Get headband of Wisdom and belt of str, dex and con. Open combat with a swift action cast of divine Favor for +4 to hit and dam(with Fates favored trait) and be the ultimate unarmed figther:) i am on the phone so i can't get a Real built suggestion. For mythic stuff i dont have the divine thing in the head so no idea there.
Bane has to be a half-orc btw.
