After being captured and tortured for months on end by Wat Tambor, Echo finally dies... and then wakes up along with the rest of Domino Squad, hours from when they're supposed to take their final test, and as it turns out, they all remember their deaths too, and are in the same exact situation. After Fives reveals the conspiracy about Order 66 that he discovered shortly before dying, they collectively decide that they will change the timeline for the better and expose the conspiracy. But it may be easier said than done...
Dominoes provides examples of:
- Adaptational Nice Guy:
- Thanks to Hevy's influence, Dogma is an amiable rookie rather than the Yes-Man stickler for the rules he is in canon.
- Commander Fox is not the useless Inspector Javert than he was in canon, instead being a stern but fair A Father to His Men, with it being implied that these tendencies are the result of Palpatine frequently using the chip to brainwash him.
- Anyone Can Die: The Battle of Kamino sees a ton of character death, with Nax and General Grievous dying.
- Back from the Dead: All of Domino Squad. It's heavily implied to have been caused by the Force itself.
- Beware the Nice Ones: Droidbait is one of the kindest people you can meet. He also holds one hell of a grudge, is a great fighter, and keeps tally marks of all the droids he's killed.
- The Big Guy: Zeer, Hardcase, and Hevy all collectively serve as this for the 501st.
- Birds of a Feather: The 501st's resident Boisterous Bruiser Blood Knights Hevy and Hardcase get along swimmingly.
- Boom, Headshot!: Attie is killed when a droid shoots him in the head.
- Brainwashed and Crazy:
- The Coruscant Guard are left permanently brainwashed by the inhibitor chip after it's discovered Hevy's was removed.
- Tup, Dogma, and several other shinies are all put under the control of the Kaminoans thanks to their chips and ordered to capture Domino Squad. They're brought back to normal after Kix removes their chips.
- Bullying a Dragon: After Ahsoka points out that Fives, having been resurrected and served the longest out of Domino Squad, has more experience than Rex, who believes that "experience outranks everything", Fives foolishly chooses to mock Rex for it. While the clones are in the middle of a sparring training session.Fives: Experience does outrank everything after all! Maybe you're the one who should be calling me sir, Rex-
Rex: That's it. On the mat, Fives.
Fives: I- Hang on, I was kidding! I didn't-
Rex: Let me remind you how much experience I have. It seems like you've forgotten.
Fives: But-sir, I just went four rounds against Tipper and Zeer.
Rex: Oh, now I'm sir again. Too little, too late. On the mat, Fives. Don't make me make it an order.
Fives: Kriff me.
- Character Development: Hevy starts thinking things through more and abandoning his shoot-first mentality, though he stays a Blood Knight. He even turns out to be a great political speaker, drumming up support for giving the clones more rights.
- Cool and Unusual Punishment: Fives's punishment for disobeying orders during the Blue Shadow Virus crisis is to give Jar Jar firearms safety training. He winds up bailing after Jar Jar nearly kills everyone at the firing range thanks to his Reckless Gun Usage.
- Deadpan Snarker: All of the clones have moments of this, obviously.
- Death by Adaptation: In canon, Echo survived his torture at Wat Tambor's hands and was eventually rescued. Here, he dies while in Tambor's custody so the story can happen.
- Defiant to the End: Slick reacts to getting caught by Ventress while exposing the Separatist attack on Kamino by making a sarcastic quip before she runs him through with her lightsaber.
- Doomed Moral Victor: Subverted. Hevy becomes a symbol for giving the clones equal rights after his death is faked so he can escape Coruscant.
- Dropped a Bridge on Him: Subverted. Tipper and Zeer are seemingly killed in a rancor attack, and Cutup even reflects that it was pointless and stupid, but it's later revealed they survived.
- Epic Fail:
Cutup: Pride comes before the fall.
- A battle droid attempts to shoot open a hatch to release the Blue Shadow Virus while mocking the clones, only for his gunshot to ricochet and hit him square in the chest.
- Fives gives up on trying to give Jar Jar firearms training after Jar Jar's clumsiness and Reckless Gun Usage, which includes dancing around while holding a gun, somehow manages to nearly kill everyone at the firing range.
- "Facing the Bullets" One-Liner: Slick gives one right before Ventress kills him for betraying the Separatists.Ventress: Traitor!
Slick: Triple crosser.
- Heel Realization: After finding out about Order 66, Anakin realizes that the clone troopers are basically slaves, and has a Freak Out. Obi-Wan expresses the same sentiment.
- Hypocritical Humor: Fives is the one who instructs the Dominoes not blow their secret about being time travelers, and then proceeds to always be the one to accidentally give it away.
- In Spite of a Nail: The Blue Shadow Virus crisis plays out mostly the same, except Cutup and Fives are present.
- Internal Reveal: It takes a while before Domino Squad reveals the truth about Order 66 to anyone else, and an even longer while before they reveal the truth about the whole time travel thing.
- Jerkass Has a Point/Hypocrite Has a Point: Deconstructed. Hevy notes that while Slick is dead-on that the clones are slaves for the Republic, the fact that he's an arrogant Jerkass who decided to prove his point by siding with the Separatists and getting a ton of clones killed still undermines his point, and that the best way to actually get the clones equal rights is to play for sympathy.
- Kill Tally: Droidbait covers his armor in tally marks for each droid he kills. Eventually, his armor is covered by them.
- Knight of Cerebus: Grievous, Cad Bane, and Ventress' appearances during the Battle of Kamino result in the mood darkening fast.
- Laser-Guided Karma: Inspired by Hevy's speech to the Senate, a clone battalion under Pong Krell's command record his abuse of them and send it to the government, resulting in Mace Windu and Ayla Secura being sent to investigate him, and then stripping him of his rank and imprisoning him for his behavior. To say Fives is happy about this would be an Understatement.
- The Medic:
- Kix serves as this to the 501st as a whole, being the one to remove the inhibitor chips from the entire battalion.
- Coric serves as this to Torrent, until an injury leaves one of his hands paralyzed and forced him to transfer to working in the medbay.
- Nice Guy:
- Attie. He's jovial, kind, and lends an ear to each of his colleagues.
- Droidbait, who's shown to be caring and kindhearted.
- Odd Friendship: Cutup and Ahsoka bond over the course of the Blue Shadow Virus crisis, and become close friends. Cutup even paints his helmet with her markings to show his deep respect and Undying Loyalty to her.
- Oh, Crap!: The general reaction of anyone who learns about Order 66 and the surrounding conspiracy is either shock or utter horror. Fox in particular starts utterly panicking, as he pieces together just why he has so many episodes of missing time.
- Redemption Equals Death: Slick turns on the Separatists to reveal that they will attack Kamino to Hevy, and is subsequently killed by Ventress for it.
- Sacrificial Lion:
- Attie is killed by droids during a firefight to show how dangerous the Clone Wars are, and hammer it in to Droidbait, Cutup, and Hevy.
- Coric, Tipper, Zeer, and Admiral Yularen are seemingly killed when the Resolute is destroyed, while Nax and General Grievous are definitely killed during the invasion of Kamino, which establishes how serious this massive change to the timeline is.
- Shell-Shocked Veteran: All of Domino Squad are pretty traumatized by their deaths, and tend to react badly when confronting whatever causes them.
- Spotting the Thread: Senator Burtoni realizes Hevy is chipless after she spitefully uses a command to get him to kill himself.
- Took a Level in Badass:
- Droidbait and Cutup slowly grow into more experienced and skilled soldiers, with the former racking up a very large Kill Tally.
- An odd variant happens with Hevy, who started off as a badass, but slowly becomes very politically savvy after being temporarily paralyzed and sent to Coruscant to serve as a spokesman for the clones.
- Tranquil Fury: Rex is outwardly calm upon learning about the biochip conspiracy; he's also utterly filled with rage.
