Through the Looking Glass is a trilogy of Multi CrossoverFan Fics by Herr Wozzeck (Not to be confused with the Alice in Wonderland sequel of the same name.) that somehow manages to cross over Sonic the Hedgehog, Banjo-Kazooie, Kung Fu Panda, and Mass Effect. The title is given because all of the fics are given a supernatural twist that would make the events of each respective part of the fic impossible or difficult to occur, depending on which part of the trilogy is being read.One can find each part here:
Through the Looking Glass: The first part of the trilogy, crossing over Sonic the Hedgehog and Banjo-Kazooie. Throughout the first book, Banjo and Rouge see each other in dreams and many, many things change in the St H world. Complete as of the present moment.
Through the Looking Glass: Penance: The second part of the trilogy, crossing over Sonic the Hedgehog and Kung Fu Panda, with a brief bit of Banjo-Kazooie towards the end. It follows Tails as he flees to China tries to deal with the fallout of the climax of the first part while helping Tai Lung find redemption from his deeds. Complete as of the present moment.
Through the Looking Glass: Elegy: The third part of the trilogy, crossing over Kung Fu Panda and Mass Effect with Sonic the Hedgehog and Banjo-Kazooie crosses prevalent throughout. It concerns Tai Lung living a new life while also dealing with strange dreams in which he lives moments from the life of Thane Krios. In progress as of its third chapter set.
Tropes that apply to this fanic series include:
Anti-Climax Boss: Tan Tao was a little easily taken down at the end of Penance...
Doing in the Wizard : Happens in Part 1, although it is partly subverted given that it does involve mystical objects and that particular reveal only explains how the pieces fit together, not exactly how said pieces would cause a dream land to form.
Dream Sequence: These are central to the story of both the first and third parts. Also appear in part two, although to a much lesser extent than the other two parts.
Dream Land: In part one, where Banjo and Rouge remember what happened vividly.
Embarrassing Nickname: Tails during the entirety of Penance. He's so disgusted with himself after the climax of part 1 that he (and the narrative) gives his given name of Miles Prower. By the end of Penance, though, he's warmed back up to it, such that by Elegy he no longer fusses about it and the narrative goes back to referring to him as Tails.
Empty Shell: Tails in Penance. He gets better, though.
Final Speech: Shifu gets a rather long one when he dies in Penance.
— Crane: "Man, it feels so awkward to know that Tigress and Tai Lung are related by blood..."
Love Before First Sight: Played with in part 1. Banjo and Rouge are in constant contact throughout, yet they never see each other's physical bodies until the climax.
Luke, I Am Your Father: Mother in this case, although said mother does exposit about the identity of the character's father as well.
MacGuffin: The Chaos Emeralds and the Master Emerald in part 1.
He's so Royally Screwed Up by the end of Part 1 he doesn't even realize when the Humiliation Conga has been pulled on him and proceeds to believe that he's taken over the world.
Master of Disguise: Tan Tao in Penance, who masquerades around throughout Penance as both himself and his deceased twin brother.
He's so good at it the characters aren't sure which is the real one for a chapter:
— Kublai Khan: "Which was the brother that truly died on the route back to China?"
Just when you think Eggman couldn't possibly get bad enough with having Tails rape Sonic and killing Klungo for no apparent reason, he then attempts to kill everybody that's his prisoner.
And then there's Tan Tao, who keeps a harem and a small personal army who kidnaps girls against their wills. Right when you think he's standard villain faire, The Reveal shows that not only did he kill his own brother in cold blood, but that he's now masquerading around as said brother and manipulating events behind the scenes to work out in his favor.
New Powers as the Plot Demands: Banjo gets this when he's able to perform a Chaos Control with the Master Emerald. It's heavily subverted for three reasons, though. The action constitutes a Desperation Attack when the only other person who could do Chaos Control at the time became a victim of a Non-Lethal K.O., it's implied and stated that the action almost killed him, and he never really needs to do it again throughout the entire rest of the trilogy.
One Degree of Separation: Tooty comes under Rouge's care, and Rouge sees Banjo in her dreams. Rouge figures out the resemblance when Banjo accidentally brings a portrait with him into a dream.
— Banjo: "You may have been bad to your friends, but... What you did for me wasn't what any bad person would do. You brought my sister back, you told me about Eggman's plans to come straight for me... And the fact that you would've done the same thing even if you knew this was going to happen... You're not a bad person, Rouge. You're not a bad person, even if you've been bad to your friends. I couldn't think of anybody who deserves to be my friend more if I took Kazooie off of that list. Rouge... Don't think like that. Please."
Pull the Thread: Arguably, the entire second half of Penance after Shifu's death is this to Tan Tao.
Rape as Drama: In both of the first two parts. Part 1 has it happen to Sonic. Part 2 actually subverts it, as it's more the threat of rape that creates some drama for Cream rather than the act itself.
Set Right What Once Went Wrong: Silver travels back in time to the events of part 1 to avoid a nuclear war that could have resulted. It's successful, although it's not entirely by his own hands.
Take That: The Lord of Games directs a big one at Amy's 4Kids voiceover.
Take That, Scrappy!: Gruntilda gets rammed into electrified metal bars by Rouge's foot when her bad rhymes become too much for all of the rest of the Sonic crew.
Tear Jerker: Sonic's funeral at the end of part 1.
Trauma Conga Line: Poor, poor Tails. He gets taken under mind control, rapes Sonic under said mind control, does so not once but twice, and kills Sonic and two other characters. Needless to say, having to process all this information when he finally regains his senses barely a few seconds after he kills Sonic leads to a minor Heroic BSOD and a massiveDespair Event Horizon that kicks off Penance.
—Tai Lung: "My biggest question right now is what the bloody hell is a siha?"
You Should Know This Already: Prevalent in Parts 2 and 3. Part 3 practically requires the knowledge that Tai Lung went with Tails for the story to make sense. Part 2 subverts it, though, treating the climax of part 1 as a plot twist.
