I've always kind of liked the idea of playing half an ettin. Get another player to play the other half, and be two characters sharing a two-headed body.
There are, however, two problems with this: the first is that the ettin is an ECL15 creature. The second is that there are no real rules for two characters sharing one body. Let's fix both of these problems.
The first is relatively easy to fix. Savage Species provides a Multiheaded template, which we can apply to some suitably monstrous creature. Applying it to mongrelfolk is too obvious. Well, hurm. What low-ECL (let's say less than 3HD and less than LA3) PC-suitable races have an intelligence and charisma penalty and a strength and constitution bonus? Let's check MonsterForge.
Abyssal maw demons, githzerai, gnolls snow goblins, neanderthals, orcs, whitespawn hordeling spawns of tiamat, and windrazor windblades. I don't happen to know what two of those are offhand, and I don't care quite enough to look them up, so let's rule out the demons and the windblades. I was about to rule out the spawn of Tiamat, but wait, what's Tiamat's defining feature? All those heads! So let's keep that in the running for now.
No, I'm not really absolutely sure what I'm looking for. I kind of want to replicate the feel of the ettin without necessarily actually replicating the ettin.
Multiheaded orc is a little too obvious, and I'm not fond of D&D neanderthals in general (If their name were anything else, it would be better, but they took generic cavemen and slapped a label which does not describe cavemen. Plus, D&D already has cavemen in spades, do we really need something that's the same as all the other cavemen except less green?), so let's rule those out. And I'd rather there be a reason. And if there's to be a fair amount of extra ECL, I'd prefer there to be a good fluff reason for it, so that rules out the gnoll.
Leaving us with snow goblins and whitespawn hordelings! Let's look up the details on these creatures. I don't happen to remember the fluff for the spawn of Tiamat, other than "Bahamut starts making dragonborns, so Tiamat retaliates by bangin' everything in sight". Or maybe it's the other way 'round. Let's crack Monster Manual IV and read!
Yeah, it's the other way 'round, the dragonborn are Bahamut's response to the spawn of Tiamat. And the spawn are not necessarily literally Tiamat's progeny, other than she caused them to come about.
I don't mind the fluff for the spawn of Tiamat, and will probably eventually use some of them in my game, but I don't think "the very weakest of Tiamat's spawn get the glory of imitating her in having multiple heads". I definitely will remember, however, that the multiheaded template is of particular merit, fluff-wise, for chromatic dragons and dragon-descended.
Okay, so, multiheaded snow goblins it is. To Frostburn!
Eh, let's ditch the throat sacs. If I wanted Kuo-Toa, I'd use Kuo-Toa. In fact, let's ditch all of the fluff and use only the crunch, we can refluff them as much as we want. In fact, let's forget the crunch and just use regular goblins, which are basically the same but have the benefit of being OGL.
So, taking the SRD's goblin and applying an extra head to it:
Small Humanoid (goblinoid)
2 humanoid hit dice
-2 Strength, +2 Dexterity, +2 Constitution, -2 Charisma.
Small size: +1 bonus to Armor Class, +1 bonus on attack rolls, +4 bonus on Hide checks, -4 penalty on grapple checks, lifting and carrying limits ¾ those of Medium characters.
A two-headed goblin’s base land speed is 30 feet.
Darkvision out to 90 feet
+4 racial bonus on Move Silently and Ride checks.
+2 racial bonus on Listen, Search, and Spot checks.
+1 natural armor bonus
Superior Two-Weapon Fighting: Because each head controls one arm, the two-headed goblin has no penalty on attack rolls for attacking with multiple weapons, and the number of attacks and the damage bonus for each weapon are calculated as though the weapon were held in a primary hand.
Automatic Languages: Common, Goblin. Bonus Languages: Draconic, Elven, Giant, Gnoll, Orc.
Bonus feats: Improved initiative, Combat Reflexes
Favored Class: Rogue.
Level Adjustment: +2
Those extra HD aren't necessary, and we could bump that LA down by removing some of the unneccessary extra abilities. Let's say this isn't just a goblin with two heads, it's a new creature, so it can lose most of the goblin traits. So let's drop the racial hit dice and the natural armor bonus, drop the Move Silently and Ride checks, reduce the Darkvision to Low-Light Vision. We're going to wind up counting it as two characters, so the bonuses to Listen, Search, and Spot checks (from having twice the usual number of eyes and ears) will be made redundant with simply rolling the things twice, so drop those, too. Getting to act twice in initiative is better than Improved Initiative, and getting to make two attacks of opportunity is nearly as good as Combat Reflexes, so those can go. The Superior Two-Weapon Fighting is important and can stay, though. And let's even the racial bonuses out a bit, no more str penalty or dex bonus.
That, according to this, brings us down approximately to 0.5 ECL at 1HD. I guess we can give it something back. Let's make it Medium and give it a strength bonus. I think at this point we've taken a two-headed goblin and turned it into a two-headed orc. Let's give it, oh, I don't know. Vulnerability to sonic, what with having twice as many ears (yes I know that's not how sonic damage works), and let's say Fast Healing 1, I was just thinking the other day that fast healing is neat. Although, it gets twice as many turns, so that would wind up being Fast Healing 2, which is too much. Let's give it DR or energy resistance or something instead. Resistance 5 to electricity, that's what we'll do, what with having twice as many hearts. Shut up, that's perfectly cromulent. And let's round it out with, I don't know, Scent.
Oh yeah, it's no longer a two-headed goblin in any sense at all, so it needs a new name. Let's call it zweikopf, which is probably not good German, but whatever.
+2 Strength, +2 Constitution, -2 Charisma.
A zweikopf’s base land speed is 30 feet.
Superior Two-Weapon Fighting (Ex): Because each head controls one arm, the zweikopf has no penalty on attack rolls for attacking with multiple weapons, and the number of attacks and the damage bonus for each weapon are calculated as though the weapon were held in a primary hand.
Sonic Vulnerability (Ex)
Electricity Resistance 5 (Ex)
Automatic Languages: Common. Bonus Languages: Draconic, Elven, Giant, Gnoll, Goblin, Orc, Undercommon.
Level Adjustment: +0
Favored Class: Barbarian.
...meh, good enough. Now, rules for two players playing one two-headed creature?
Well, it shouldn't be weaker than two separate characters. That's an easy trap to fall into. This isn't really just one creature. In general, it should be treated as two separate creatures sharing a square.
Some of the things you need to consider (and my solutions to them):
Each character buys/rolls ability scores normally. Each character gets the racial modifiers applied to their scores separately. Each character uses their own ability scores for anything they do, as if they were a separate creature. (Yes, it's entirely plausible that you might see a creature with one huge bulky arm and one tiny dinky arm. Which is fine; have you ever heard a description of a blacksmith? Same deal, and that only with one head.)
Each head earns experience and gains levels independently of the other.
Any feats or flaws taken by one head apply only to that character.
Each head rolls their hit dice and adds their constitution score every level. These hit points go into a shared pool.
Any damage taken by either head is subtracted from the shared pool. Any healing applied to either head is added to the shared pool. If this pool reaches 0, both heads are disabled. If it falls below zero, both heads are unconscious. Only one head rolls to stabilize each round, and the pool only loses one hit point per round when the joint creature is not stable.
Any other creature subjecting the zweikopf to any effect must choose to target one head or the other, though this choice may be random. Each head uses their own AC and saves. Any effect which targets multiple characters can target each head individually, as if they were separate creatures.
Any items worn on the feet, fingers, hands, arms/wrists, shoulders, body, and torso slots affect both characters. (Items that function only if both of a pair are worn still function only if both are worn.) Each character has their own head, eyes, and neck slots; any magic items worn on the neck, eyes, and head slots affect only the head wearing them.
Each head can wield and use a one-handed or light weapon with no penalties. Wielding a two-handed weapon takes more coördination than the two heads can muster.
Each head rolls their own initiative. Each head gets actions (move+standard or full round) as if they were a separate character.
Each head can move the body as a normal character. However, each head's move speed is half the listed move speed. Either head can choose to veto any movement attempted by the other; if this happens, the joint creature falls prone.
If a creature provokes, each head may make a separate attack of opportunity, as if they were separate creatures.
