Giving a Sue to AM. Or throwing her into Nahgharash.

I think portaling Sues to Reaver ships would be too harsh.

I pretty much agree with averything here: it can't be anything too horrible or realistic like rape of calamity and until Cthulhu gets down to 32000 tonnes he's on a strictly Sue-free diet.

However, what about a sacrifice to Shub Niggurath?

He/She/it is apparently relatively beneolvent to humanity and besides, I don't think a water buffalo alone will have quite the oomf for a proper sacrifice to her Buffalo cow/Black Rooster/Black pheasant hen manifestations. If someone could donate some relationship sues for said sacrifice (sometimes in the future), I feel that the Black Goat could be quite forgiving in the chcolate/soda/potato chip department.

I just hope she likes sparkles.

All funniness aside, there are certain lines we do not cross. Rape is one of them. It's the main reason Drip Rat and the Redneck Trees from Something Positive are off limits. No punishments involving rape are allowed, because they fall firmly under Not Funny. Also, it's a bad idea to trivialize horrific Real World events and crimes when making up assassination methods. So I wouldn't suggest putting a condemned Sue in the World Trade Centers, or a Nazi death camp, or a room full of KKK members.

I agree with Aster Corbett that a fitting death is usually in order. My favorite missions end with something suitably ironic based on what type of damage the Sue inflicted on the setting or characters, if only for the sake of making me feel better. :3

Torture is perhaps a step too far. That said, C*l*br**n. No need to make the Sue's last minutes that painful.

Anything too extreme... Torture's been mentioned earlier. That includes waterboarding, sleep deprivation, etc.

Using the t-Virus on them is out, if FEV is any indicator, along with the G-Virus. Honestly, G-Virus infected are notoriously hard to kill anyway, so it would be a Very Bad Idea to give a Sue it. (Knowing various Sues' powers, they'd probably keep their mental capabilities, which makes it an even worse idea.)

Sues aren't really alive (being mostly the manifestations of temporary self-serving desires, I guess) so assassination I feel is less 'punishment' and more 'sentenced to a fitting death.'

Most elaborate deaths are a) maybe the only thing that can kill the Sue or b) serve to make the agents feel better, so I would say that a punishment too horrible for a Sue would REALLY be one that is too 'harsh' to be in the spirit of the PPC.

Like doing something horribly unfunny.

No funny thing is too 'harsh' for Sues.

I'm not certain such a thing exists when you're talking about Sues.

Several forbidden and frowned-upon methods of assassination that have not been brought up yet should be touched upon, however. They are:

--anything involving rape (ex. the Reapers from Firefly, the Darkspawn from Dragon Age)

--anything that trivializes a historical atrocity (ex. the Holocaust)

--anything from the Forbidden Substances page (http://ppc.wikia.com/wiki/Forbidden_substances)

Handing her over to the 456 from Torchwood. That can only be done with prepubescent children anyway, so it will rarely be an option.

Pushing a Sue into the Sarlacc Pit also strikes me as a little over the top.

And everything the Doctor did to The Family of Blood.

Admittedly, all of those are also in part, because I don't think a Sue should ever be left alive, no matter how impossible escape seems.

. . . I consulted with my brothers (both ex-USMC) about likely fates for the Sue, who was an overpowered bully in a military setting and disregarded rank, chain of command, or anything else in her quest to be Big Woman on Base. They gave me several ideas, which I unfortunately couldn't use because they might have technically run afoul of the torture clause. The two I remember are:

1) The ironing board treatment. Take the offender outside, place a common ironing board on top of them, and start piling the board with the heaviest things you can find. Has been known to happen to servicemen that screw others over (the way the Sue was doing), but it smacked too much of the old crush-a-witch-slowly thing.

2) Suicide watch. This one's psychological torture. If you hate someone, and the whole unit is focused on making that person's life miserable, one of the worst things you can do is have that person put on suicide watch. Now, in addition to being loathed by everyone around them, the hated person is never allowed to be alone and gets woken up once an hour every night. Ostensibly it's to make sure they don't kill themselves, but it's really just to drive them insane and make them suffer sleep deprivation. Again, it was too close to torture, and I had to shelve that one.

Moral of the story: don't consult with vengeful military guys when trying to dispose of a military Sue. Anything they propose is likely going to cross the line.

Torture is out. Full stop.

If it qualifies as torture, even if you squint, you probably shouldn't use it in a mission. That is to say, so long as it's a clean kill, it's not overkill in my opinion, at least.

For example, let's put it this way. Say you decide to kill a Sue with fire. There're two ways you can go about this.

1) Setting her on fire, or;

2) Carefully burning her bit by bit and keeping her alive and awake through it until she's entirely burnt up.

It boils down to the same thing, (Sue Flambé, anyone?) but the execution is entirely different. With the second, you're willingly and consciously prolonging the pain and misery caused, and forcing the Sue to be conscious and aware of what's going on.

The first is a painful death too, yeah, but you aren't making the conscious choice to make it more painful or terrible than it is by default.

That said, I don't think there's anything wrong with scaring the crap out of the Sue before you actually get to the causing of bodily harm portion. (Like, say, waking the Sue up in the dreaded Room 101 and telling her.)

Being forced to read The Eye Of Argon immediately springs to mind...

Or C*l*br**n.
