i would probably say master of many styles monk/slayer personally that dude has mad fighting skills and pulls of some cool combat stuff that you would need a few style feats to pull off just make sure you arm him with kukris just reskin them to curve the way they do instead of a normal kukri use the slayer talents to pick up the twf tree hes definitely an str build so pick up double slice as well, ill be back with more input tomorrow
He's definitely not lawful though... Maybe winding path brawler?
he follows his own creed of sorts so i could see an argument for him being lawful, besides alignment restrictions are dumb and should be removed in all circumstances, and if you want to make something cool and it uses a class that has those kinds of restrictions ignore them and make your cool thing for the party to enjoy
not that i know of however you could vmc fighter and pick up the focused weapon advanced weapon training ability which will net you warpriset sacred weapon damage with the weapons which while not strictly as good (caps at 2d8 as opposed to 2d10) will still be much better then the 1d4 base from the weapons but will give you 18-20x2 crit range (15-20x2 if keen or improved critical)

He didn't have an animal in either Pitch Black or Chronicles. (He's friendly with critters, but they don't go with him or do anything.)
Hmm.... Ranger6 ([Guide][Infiltrator][Skirmisher]), Swashbuckler12 [core], Fighter2
-- This gives him I-TWF, Darkvision, replaces spells with (pick a goodie, probably +10 Perception as Immediate action), Favored Enemy (pick any chump), and a whole butt-ton of tricks with light weaponry + Evasive.
...or Ranger9 (for Evasion) + Swashbuckler1 + Ninja10.
Those archetypes can't be had together. One gives up favoured terrain, and another is built off it. Also, with it being gestalt, I don't need to split it like that. But great ideas all. I'm assuming that for mythic, give him the dual tiered feat, champion/trickster would be best. What other mythic feats/abilities would you suggest?
