Ninja/Gunslinger I think would fit pretty well for Snake eyes. Then again my friends are of the mind that ninja should have been based off of the monk instead of the rogue.
That's ludicrous, Ninjas are really bad at the law, they're much better at breaking the law than maintaining it, plus they aren't known for their kung fu* as much as their weapons. They should be somewhere in-between (which they basically are): crazy Wu-shu powers+sneaky-backstabbing-dirtbag. Though I think they should have martial weapon proficiency, because ninjas will use ANY weapon they can get their hands on.
*Or rather, they shouldn't be.
I don't know about a link, but there are a bunch of ways for barbarians to get natural attacks now....it's easy enough to call those claws and a few of them already are. Dwarf barbarian wolverines abound!
While making him a hairy dwarf is tempting I had PF Logan pegged as a human wild stalker ranger / invulnerable barbarian so far.
Chuck Norris...Witch Hunter?
So now I have seen a Superman build for Pathfinder and for the most part I can see it working as a version of Big Blue. I remember creating Supes for a new player back in the 96. He liked having the power, but he didn't use it as a boyscout would. I suppose it is time for me to have a go at it again, just to appease myself.
Superman:
Race: Kryptonian (Race will have to be created using Advanced Races Book)
Vulnerable to magic (big problem in this world), and kryptonite (a mineral that would have to be introduced by the GM)
Abilities: A plethora of different visions, heightened senses, etc (we know the whole thing, so I will cut to the chase as to class)
Class: Cavalier Order of the Boyscout
Knows how to use virtually any weapon and/or armor and shield, but only uses them in dire times.
I will have to work on this a little later seeing as how it is 3:30 in the morning here and I need some sleep. Please feel free to offer input on this and any previous ones, too.
For Iron Man (and other power armor genii), I think Dreamscarred's Aegis (Unlimited Possibilities) might be an even better fit than the Synthesist- it is a intelligence based martial class with an costumisable "astral" armor and some craft boni. Unfortunatly, I have only be able to ind playtests and no noverview for the final class until now (you can already build them with PcGen).
I can't believe this hasn't had any comments since 2012, but Thor would be an easy Barbarian/ Tempest cleric I would think.
