Tank/ bruiser builds or any other cool ideas

[CrispyKingPin]

So i've never played pathfinder, and my DM is a little new to it as well. However he has a lot of 3.5 experience.

Anyways to the point, It's a evil campaign, not my choice, but i'm fine to roll with it.
We have a alchemist, a wizard who focuses on enchantment, and a fighter/sorcerer.

I'm up for ideas of any variety. However I'd prefer to be a beefcake kinda character. I am starting out lvl 5, so level adjustment is fine, i'm a fan of exotic races actually.
But prestige and class advice is welcome. Any type of combinations you have I will feel free to listen to, and like I said it's a evil campaign, so evil prestiges are welcome.

Shield Champion (http://www.d20pfsrd.com/classes/hybrid-classes/brawler/archetypes/paizo---brawler-archetypes/shield-champion)!Brawler (http://www.d20pfsrd.com/classes/hybrid-classes/brawler). You'd be like evil Captain America.

You could also go Warpriest and demand more blood for the blood god all the time.

Pathfinder martial PrCs mostly make excellent toilet paper. Instead, PF supports archetypes to customise your character class, like the shield champion Minty mentioned.

IMO the best beefcake is a barbarian or bloodrager. An abyssal bloodline bloodrager can do the demonic monster really well, a barbarian who picks rage powers like superstitious and spell sunder is both a solid frontliner and somewhat prepared for in-party betrayal. You can combine these ideas by taking the primalist archetype for the bloodrager.

PF also doesn't use LA. There are some sort-of substitutes for it, which are clunky enough that they don't usually get used, and so races like drow nobles just don't get used either. Anyway, if you don't want to be one of the standard races there are things like aasimar or tiefling variants which'd work well for a bloodrager (angel-blooded or demon-spawn respectively).

If sorta third party is available then the Warder is an excellent meatshield/tank/bruiser. And by tank i mean they can actually tank, which is something you really can't do with other classes.

Meet the Warder (http://www.d20pfsrd.com/path-of-war/classes/warder). You're an Int-based tank with powerful attacks and a "zone of Nope." Have a handbook (https://docs.google.com/document/d/1Nuni1TCzVXyhx4rFWjNcEjuDS6goL9hLQDE4il_tzH8/edit?usp=sharing).

Want to be tanky, but don't want to use shields? There's an archetype (http://www.d20pfsrd.com/path-of-war/classes/warder/warder-archetypes/zweihander-sentinel-warder-archetype) for that. Two (http://www.d20pfsrd.com/path-of-war/classes/warder/warder-archetypes/dervish-defender-warder-archetype), actually.

PoW gets you maneuvers, which give you powerful combat options. The Warder class itself gives you the ability to defend yourself and others. The total package gives you a unique and exciting way to punish your enemies for looking at you funny.

Enjoy.

The Warder is a 3rd party class that is basically the Tome of Battle Conversion for Pathfinder, now you said your GM had a lot of experience with 3.5 ask them if they have heard of Tome of Battle and whether or not they approve of it before looking into the class that has been suggested.
