Becoming a demon http://www.d20pfsrd.com/bestiary/monster-listings/outsiders/demon.
Literally just be a succubus. Requires a lot of effort, but unlike lichdom or grave knight, or any of the other op evil options it's actually pretty cheap.

Ok, aid another is +2. The text says you add the enhancement bonus to the aid another bonus which to me suggests that its an enhancement bonus to the +2, not to your AC. Furthermore, its an untyped bonus in the first place, so the fact that its an enhancement bonus is not really important. Your barkskin +2 enhancement bouns to nat armor doesnt prevent your +5 armor from working. So to summarize, aid another gives an untyped bonus to their ac, and you apply the enhancement bonus to that, not to their armor bonus like their +3 blessed greased grey dragon scale mail (if you dont get the reference im sad but its ok).

Just put on your +2 int headband of now im a lawyer (profession barrister, wear for a week or whatever) then call up a contract devil with planar binding and very very carefully word three wishes to gain immortality. If you die you are completey, irrevocably screwed. Dont mess up the wishes. Usually using the first wish so that the 2nd and 3rd can't be subverted is a good investment, but it really depends on how strong your lawyer-fu is (higher lawyer-fu means less value from safety wish). Just my two cents here.
Edit: its 24 hours to get the skillranks.

Rough and ready trait methinks. (use tools of proffesion as weapons) "This trait is commonly used with shovels, picks, blacksmith hammers, and other sturdy tools"

Alchemist is the greatest hands down. Wanna build constructs? Army of undead? Simulacra? Break action economey? Break economey? Melee dpr? Ranged dpr? Party debuffer? Better rogue? Quite literally a character that can go anywhere. Not a liability early, dominates midgame, solid lategame, class is perfect.

My best advice would be to have at least 10 illusory ion torches as well as as many real ones as you can have orbiting your head so they don't know which one to attack

Sundering build using greater sunder with a maul of the titans and spirited charge as a druid with one of the giant masks so your huge and you smash stuff. Bonus points for cohort or party member throwing red cloaks on people so you can sunder the dragon (matador anyone?) also raw dmg bonuses for maximum goodness, abilities for ignoring hardness... anything im missing here?

Edit: Also the lantern archons are really really good if you summon enough of them (touch attacks that bypass DR)

@DualJay

my objection is mostly in the fact that the PC is being treated as though it can adjust to whatever the monster does, whilst the enemy is forced into a predetermined, and suicidal action. Yes, I will admit that as a test of if you can do X DPR against different sets of AC, DR, and Regeneration, or beat a save array of X, Y, Z with immunities to whatever, it is pretty good. However, it is not actually an indicator that you could actually beat these creatures in a "fair" fight.

Edit: the biggest problem with the challenge is anything that can go in a surprise round is really imbalanced, because with halfway decent initiative, none of these even get an action. also explain what spells you use to infer your next opponent with 100% accuracy.

an old dwarf sits at a a table with an elf. They are playing chess and talking earnestly. The dwarf's armor is mauled and battered, barley holding together, and his face is covered in scars. The elf doesn't have the same level of visible damage, but looks on edge and flinches at the slightest movement around him from anyone but the dwarf. The dwarf downs ale after ale all night, but he continues to hold even with the elf in the chess game, despite being mildly drunk.

Perception: listening to thier conversation reveals that they are retired demon hunters now on the run from cultists.

Build an adamantine box on my shoulder, and enchant it to be pretty much immune to everything.

Put permanently shrunk gnome witch with cackle and fortune hex in the box.
profit :)

That and having a bunch of lvl1 followers be wizards with true strike and having them man the ballista on my airship.

Or building a bounty hunter with a caceodaemon familiar to get the soul gems, and a portable hole to keep the bodies to sell to necromancers, specked out knowledge skills to know who to sell this stuff too, and just go maximum profit in an evil campaign.

Or using wish to reduce the opening of a everflowing bottle thingy 1 micron diameter. Due to the flow being a constant number of gallons... they make great engines for your airship of doom... or you can just turn it into an adamantium cruise missile.

Go Bard (Soundstriker And Dervish of Dawn) 20/Rouge 10/Arcane trickster 10
With Cha 31 (18+2 racial+6enhancement+5 levels) you deal:
10d8+180+100d6+20 Str damage (crippling strike advanced talent)
Keep in mind that this is a standard action, and you still cast spells as a level 30 bard,
