I pronounce it Foo-koo-uh because that's how you would logically pronounce it.
Well, here's my thought. In all seriousness.
I don't mind if they actually go through with keeping her in the game, but no, I don't want her to be "canonized" as a character. It would be kind of hypocritical of Lab Zero to make a character as a parody of a clone character and then go on to make her a "legitimate" clone herself, wouldn't it?
If anything, they should play up how intentionally bad she is at least visually, tweaks to gameplay notwithstanding. Don't make her look any better, don't improve her animation quality, definitely don't try to actually include her in the story. Make sure she stays firmly cemented as a tongue in cheek joke character. The last thing SG needs is to be getting backlash for having legit clone characters, sheesh.
