I've been reading these in between work shifts, so I likely won't remember everything I had wanted to say, so . . . in a chaotic ball of free association, here are my thoughts and corrections:
To start on a general note, something you've done super-well is setting things up way in advance, and making everything run together. This goes back to your first mission, where you introduced Eagrus' distaste for technology, and the malfunctioning of the disguise generator in the "Mulan and Shang 300" mission. Both of those pay off down the line, with Cyba's Borgification and the Borg-heavy Star Trek mission. The same goes for replacement!Shang in the first Mulan mission calling the agents Huns, and turning that into a running gag. These sorts of things give your spinoff some real glue between the installments, and help it flow better as a long-running story.
As for other things I liked, I liked that the mini-Colossi have such strong personalities, and interact with both agents as well the console frequently and in different ways. You made good use of the comma storm to unite the Mulan missions. (And also to keep the disparate Ancient China and modern day bits together. Seriously. Talk about clashing cultures.)
I super muchly loved the Star Trek mission! That piece, while taking the call-forwards from the other missions I already mentioned, was particularly cohesive in and of itself. I especially loved the focus you put on the Borg culture, and how you turned the Sue's descriptions and actions back on himself at the end. Part 2 had my absolute favorite bit, where the Borg's hive mind started infecting Cyba's mind (and Cyba cubed's minds). This majorly underscored the real threat the Borg poses in the Trekverse, and contradicts the account of them presented by the Sue, which is the sort of thing I love in PPC missions: giving the canon a chance to show its stuff after being degraded by the original fic's bad writing.
And now mistakes I found! (Apologies if these have already been pointed out, but I can't stay up any longer to read all the comments.)
Mulan and Shang 300
""Don't sat tha-" Eagrus was too late." (say instead of sat)
Fas Mulan: I just wanted to point out "Fa" is the family name given for Mulan's family in the Disney movie. You seemed a bit confused by it (as was I, when I encountered it in my own claim to these mini-fics. :s )
Between the lines, ""We have to wait that long?"" and ""Oh no," Eagrus corrected her." the font you're using changes.
Parenthood
" . . . to encourage yet another immanent punctuation storm." (imminent instead of immanent)
" . . . heard the terracotta soldier say, now moderately discernibly." (two adverbs in a row, lol)
Parenthood 2
Alright, alright, we're coming!" cried Eagrus. (missing opening quotation mark)
Untitled 1
" . . . trying to her mind off her destination..." (missed a verb)
Love and War part 1
Another font change here, between ""Since when would Kes and Seska faint over a dog-man?!" pointed out Cyba furiously."" and ""Oh look, he wants to come 'abored'," snickered Eagrus."
Love and War part 2
" . . . snapped the trio of Cybas in unison. "Then they exchanged glares . . ." (Oh look! The missing quotation mark from "Parenthood 2!" (: )
"Sigma cuffed him with her metal arm . . ." (This isn't a typo so much, but the sentence before this one had Eagrus off-handedly referring to the Borg as monsters, so when I started reading this one, I assumed (based on Cyba-cubed's increasing protectiveness of the Borg) that Sigma was hitting Eagrus until I got farther into the sentence. You might want to rewrite this sentence a bit to make it more obvious that it's the Sue getting socked.)
