Hmm... I feel as if "is this power as strong/synergistic as it could possibly be" should be secondary to "is this power going to fun/interesting to read about". My opinions on each:
-Fedorable is... well, interesting I guess. At the very least there's a chance for a lot of variation and potential for "acquisition" quests, of sorts. Hard to mesh it well with any other options thematically though.
-Passive-aggressive negotiations is basically a pretty weak thinker power. Don't see the point, especially given that a crack quest is likely to go more dangerous places than this would generally take us. Could be used for maximum taunting in battles, but how likely is QA to really do that?
-Mic drop is a slightly weaker Imp power. Could be interesting, but not without something to go with it.
-Administrative access: could be kind of fun, particularly the hardware one, though I imagine several of the other powers make this somewhat irrelevant in all the typical ways one would use it. Has some potential.
-Form Control/shapeshifting offers a lot of possibilities both in and out of combat situations, regardless of what else is taken. I like this one a lot, and it almost certainly has my vote.
-Zerglings and other bio-tinkering stuff has been kind of done before. I've already seen them in several Worm fics/quests, so I'm not particularly partial to this option.
-Dreamer is kind of cool, and funnily enough thematically fits for what's going on, but needs some other draw or addition to really be useful.
-Cat-based Teleportation: I like this one, but like Mic Drop it's potentially too much of an easy out. Still, the previous version of this had REALITY WARPING, so power may not be something I should be taking into account all too much.
-Save scumming- uh, the whole draw to this quest was that Taylor ISN'T the one in control, and QA is the one making all the decisions. So, no.
-Read/write senses: Not sure where smell is relevant outside of Lung and Bitch's dogs, but yeah, has some serious synergy with the teleportation one. No denying that. Do not like however, because that is basically just a near-unstoppable "I quit" button.
-Read/write memories: in any other quest, I would say this is likely one of the best powers in the Wormverse for the PRT/Protectorate, as it could help erase trauma from trigger events. At the same time, they'd be really wary because memory overwriting is basically a master power, and QA would be stuck in that morass of boring and distrust and yeaaaaaah maybe not. Too slow to really be used in a fight, though just read access has potential if this ends up a less combat-focused quest.
