Well it's not easy. It won't be perfect, but you can come pretty close:
Stats: STR10, DEX18 (human+2), CON14, INT10, WIS10, CHA14
Levels:
1) Unchained Rogue, TWF, Toughness, Max: Acrobatics, Bluff, Sleight of Hand, Disable, Escape Artist, Perception, Stealth, & whatever you want. You use dual Short Swords for now & you talk a bit of trash.
2) Magus (Eldritch Scion), Destined or Fey Bloodline, Infernal Healing as your level1 spell, accompanied by True-Strike or Vanish. Cast Healing before combat while ridiculing your enemies.
3) Rogue2, firearm training if you can afford a pistol. Weapon Focus: Short Sword or Kukri (while complaining to GM that Katana is not a Finesse weapon). Take some time every few rounds to discuss your opponents apparel.
4) Rogue3, Here's where you start trucking kids & healing through what damage you take. You've bought bluff 4x, so you have a 9 and you use it constantly to make your friends and foes alike suffer. You are insufferably annoying in every way to all around you despite being useful and courageous in your murdering-of-the-bad-guys.
5) Either more rogue or magus. Buy TWD or Dodge to make Wade even more annoying. You want the people at PFS to groan in despair when you sit down at the table, but not outright ban you from the event. #maximumeffort
It's lots of acrobatics, bluff, sleight of hand, and sabotaging-the-talky-parts-of-the-adventure. Suggest you align CG for PFS. Be the Deadpool that desperately wants to be in the Xmen but can't quite fit bc rules are no bueno.
Eventually you might pickup improved feint and more levels of Magus.
You could do deadpool with straight magus & a 14-16 str. Then dual Katanas would almost work (you'd still miss a lot but that just adds to the comedy...). Mostly the rogue rounds out Wade's skillset & general attitude towards society.
