The default, so no traits needed.

[*]immortal (time-wise) and hard to perish (pointy-thing-wise);
Unaging -- though many people consider this overpriced even at 15 points unless your game happens to include a lot of aging attacks or covers a long enough span of time that avoiding aging rolls is going to matter. Age by itself doesn't convey any advantages; it's an excuse to have other traits (like lots of knowledge skills or Area Knowledge or History because you lived it, which you'd buy separately). You might well think it's just a 0-point Feature.

Hard to Kill (can still put the character down from damage, but they're less likely to fail a death check -- so down, but not dead)
HP (harder to down because there's more HP)
Injury Tolerance (very hard to damage in the first place)
Unkillable 1/2/3 (varying degrees of coming back from death, such as fey losing their form on the mortal plane and having to recreate it before they can come back)
Supernatural Durability - the Terminator or Jason / Freddie type from a slasher movie.

[*]charming, foppish and playful, at least at first glance;[*]offputting and creepy at a second glance;
Mostly RP or Quirks, I'd say, but you can try some counteracting traits.
Charisma (charming)
Supernatural Features (to become offputting on closer acquaintance)
You might also try Reputation (offputting and creepy) greater than the Charisma, but negative, to try to model being creepy after you get to know him. So bonus early on, malus once the Rep kicks in (though mechanically the Charisma is still there, so it's not as bad as it looks). You might also classify "offputting and creepy" as an Odious Personal Habit.
[*]implacable alien mindset;[quote]"Alien" needs definition; it's too vague to do anything with. "Implacable" could also use some refinement - see Fearlessness, Indomitable, Single-Minded, Unfazeable, Fanaticism, Stubbornness,
[*]a heartfelt yet fleeting fascination with mortals;
Chummy (just rotating who he picks as "company")
Xenophilia (for humans, noting that "strangers" soon stop being strangers, which you could take as the "fleeting" bit. Fascinated with humans that are strangers; once he gets to know them, he's bored and moves on)
Compulsive Behavior (meddle with mortals)
[*]deceitful and manipulative, although incapable of lying directly;[*]constrained by laws which they only respect the letter of;
Callous
Truthfulness probably isn't appropriate, as it hurts ability to lie or lie by omission.

Code of Honor (Fey -- which you'd have to detail, but mainly "never break the letter of fey laws / promises")
[*]powers of enchantment, illusion and travel between worlds, but generally has to bargain, coerce or persuade the consent of mortals before affecting[*]a limited ability to manipulate reality, or just access to untold treasures and ancient lore, enough to "grant wishes" of sorts.
them;
Mind Control
Enthrallment skills
Illusion (Powers 94)
Jumper (between Faerie and the mortal world)
Snatcher (access to untold treasures)

Some people have suggested using Jumper to "manipulate reality", given the presumption that an infinite number of slightly varying worlds can exist. Consider the fey taking all the PCs to a world just like the one they left, except that it has exactly those changes the wish is supposed to grant -- the PCs are royalty, or wealthy, or their hated enemy is dead, or the year is exactly 360 days long, or whatever. I've never tried it in play myself -- but taken literally it seems like a truly godlike power.
Ability to actually change the PCs in any manner is probably a Modular Ability for Affliction, Permanent, with enough points to cover whatever changes you want to be able to make to their traits (making a PC stronger, smarter, giving them Lucky, Magery, removing their Disadvantages, etc).

More individual generic fey traits might include Impulsive, Jealousy, Intolerance (of mortals), Overconfidence, Short Attention Span,

In my experience, giving one PC a huge number of cp that the others don't have leads to major problems. I've done it, the other players were resentful.

If you want a 150 point campaign, then allowing one character to start with 500+ points could be a problem.

This is very much like having a GMPC.

Just my opinion.

I completely agree. Ordinarily, this is a Very Bad Idea(TM). I'm only contemplating it because I've known these people for 20 years and roleplayed with most of them for about as long; they live for stuff like this. Personally, I like things to be balanced - they like whatever makes the story more twisty-turny, and chafe at having to wrangle their character concepts into the typical mold of a 1st level D&D adventurer.
