13xwhat?!
Basically, this is just my opinion on almost any possible yaoi couple dealing with Treize. The squick factor is rather high on some of them, so consider yourself warned.
OZies
13x6/6x13 - By far my favorite couple. There is so much potential for this couple, I mean, they've known each other since they were kids. Isn't it possible that somewhere along the line friendship became something more? Heck, aside from how plausible the couple may be, it's one of the most visually appealing in Gundam Wing. I know one person who's not a yaoi fan who admits that the two of them would look incredibly good together. That said, let us move on to some of the weirder couples�
13xOtto - Er�no. We all know Otto worships the ground Zechs walks on, right?
Tsuberovx13 - EEEEEEEEEEEEWWWWWWWWWW!!! OYSTER! Icky, icky, icky!!! So in other words, no, not in a million years. Ew! I think I need to wash my eyes out....
Dermailx13 - Not much better that the one above it. That's just nasty. Besides, that's incest or something like that.
Gundam Boys
13x5 - I don't like this couple, partially because it means no 13x6 and partially because I just can't see it happening. Granted, Wufei is a bit obsessed with Treize, but Treize doesn't seem to see Wufei as anyone but a worthy opponent. Also, the two of them meet only twice in the series. When did they find time to *ahem* ?
13x4 - Er...I really can't see this happening. No matter how you look at it, the two don't mesh. I just cannot see Treize and Quatre together...
13x3 - Actually, this couple would be kind of amusing: the most eloquent speaker in GW and the person who speaks least in GW. ^.^ 3x4 or 4x3 works much better, but I think 13x3 might be an interesting relationship. Hey, Trowa *is* part of OZ for a while�
13x2 - This is another one that I just can't imagine. It just won't work.
13x1 - At first I would say that this is another one that just wouldn't work. But, after some thought, I decided that this one is kind of like 13x3 - Heero works better with Duo, but 13x1 could make for an interesting relationship. After all, Treize does give Heero the Epyon and they both seem to respect each other at least.
Other
13x6x5 (Or any other order of that) - Mmmm�yummy, almost as good as 13x6 in fact. If Wufei absolutely has to be involved with Treize, I prefer it like this.
13x1x2 (Or any other order of that) - Nah�6x1x2 could be interesting, but this just doesn't work.
13x3x4 (Or any other order of that) - Might be interesting if it started out as 13x3 them moved on to a threesome.
Conceivably, there are a bunch of other threesomes that could involve Treize, but I don't feel like listing them all.
