Zero's Shock is a crossover between BioShock and Zero no Tsukaima written by the same author who is giving us Toy Hammer. Simply put; Jack becomes the Familiar of Zero. While the fic is still in its infancy it has a promising start, with Jack and Louise both having a lot of character depth for a Silent Protagonist - a trait that is somewhat retained - and being spot on with canon (barring the domestic abuse - Jack doesn't give her a chance for that), which has earned this fic praise from the reviewers on fanfiction.net.Also, there will be BEES.Word of God says that this is based on a hypothetical in-between ending where Jack becomes King of Rapture while still having the favour of the Little Sisters. Said ending is shown through flashbacks, which gives us glimpses of the Rapture 'Reunification War', with Jack, Tenenbaum, and the rest of the BioShock cast, providing us with Character Development to see how Jack became who he is now.
Salvatore: They're making [Jack] an honest-to-God messiah down here in the slums, and once someone breaks that pedestal, all hell is going to break loose, and we are going to be in the center of it all when the shit hits the fan... and they're gonna blame everyone.
Butt Monkey: A literal Leeroy Jenkins is killed repeatedly (sometimes accidentally), only to be revived via Vita-Chamber to continue on with experiments to try and bring back Jack.
Well, there's also the fact that he doesn't have much tolerance for drama, something he makes very clear to Louise.
Evil Sounds Deep: Inverted. Jack's not evil, but his voice is very low and guttural because of the Big Daddy modifications he underwent at the end of the game. This is part of the reason he rarely speaks, and when he does he compensates by raising his voice a few pitches. He also has one hell of an Evil Laugh, one scary enough that it even makes Big Daddies stop to turn and stare.
Face Palm: Practically a staple reaction of Jack to the [ZnT crew's antics.
Fantasy Kitchen Sink: Halkeginia is a world on the doorstep of the Renaissance and contains magic (and magical creatures related to such a setting). It has also been crossed over with BioShock, known to have at least taken things from Halo and Pokémon and possibly others... well, you'd expect this trope.
Derflinger: "Golems this big always have a magic-saturated catalytic core to help run the whole thing! Its like the heart, or a lung, actually. Maybe a kidney? Dunno about squishy bits, you people have such complicated names for them."
Instant Expert: Played with in a meta context. Jack seems to be an Instant Expert with his plasmids during the events of BioShock, but here it is subverted in that the plasmids can be much more effective and more EVE efficient after he's gotten some practice in.
Irony: Noted by the author: At the moment, Rapture (a formerly free-market capitalist society designed to be Ayn Rand's utopia) and its population would be more than eager to crown Jack a king or equivalent thereof if it had more spare time from rebuilding after the Civil War. However, most of Halkeginia (a pre-Renaissance era + magic setting) is itself on the verge of a commoner's rebellion (which is, in canon, already in progress up in Albion), which would push its society towards capitalism...
The Lancer: Salvatore, back in Rapture, acts as one for Jack and perhaps later for Tenenbaum as well. Shows hints of becoming a Supporting Leader as well.
Oh Crap: Jack's enemies whenever he starts using plasmids, especially since they're much improved over the ones found in the games, with this Jack having much finer control than 'burst of fire in that direction'.
Original Character: One of the rare non-Mary Sue ones in the form of Salvatore; he's a splicer who acts as Jack's right-hand-man back when he was still in Rapture.
The Quiet One: Jack isn't totally silent, but still displays economy of words. So far, his longest speech is six words long.
Floating continent?! The splicer tried to wrap his head around the concept of a floating city. Sure, Rapture was a bizarre place on its own, but it still had a foundation! It was at the bottom of the sea, rather than in the freaking sky!
Terse Talker: Jack and Tabitha barely speak more than one word each time they open their mouths. When they have their first conversation, which Kirche states to be the longest conversation Tabitha's had with anyone ever, it's entirely done with one-word sentences.
