It follows the adventures of the entire cast of Smash Bros, and a handful of OCs, who mostly reside in a massive hotel run by Mark, the Hands, and the Announcer. Assist trophies live in the Smash Motel, a much smaller and more run-down building.
One Big Smash-y Family contains examples of:
- Actor Allusion: The Announcer's name is Xander.
Sonic: Anyone ever tell you two that you sound exactly the same?!
- A different one was lampshaded by Sonic in Chapter 34, since Male Robin and Richter share a voice actor (David Vincent).
- After-Action Patch-Up: Tiki to Pit, all the time, even before they get together. In Chapter 63, she is voted by the other assist trophies to care for a knocked-out Pit. In Chapter 106, Pit has passed out from his Mii-related injuries trying to protect Palutena. Tiki sits by his bed the whole time, holding his hand. In Chapter 170, after getting the memories beat back into him by Dark Pit, Pit heads to the Motel and gets patched up by her again.
- Big Damn Kiss: In Chapter 190, after dozens of chapters of Unresolved Sexual Tension, Wolf and Isabelle finally kiss.
- Cold Equation: In the Reset Arc, Sonic downplays Chelsea's death by saying that they'll bring her back with everyone after they reset. He also uses this logic to justify anyone dying as a result of his idea to split up.
- Continuity Cameo: In Chapter 86, Simon invites Kevin Keene and Princess Lana from Captain N: The Game Master for Visitors' Week.
- Deader Than Dead: In the Reset Arc, Pit falls into lava. And this time, there was no Palutena or Rewind Spring to save him.
- Decomposite Character:
- Villager has become eight characters, each with distinct personalities, based on their eight palette swaps.
- Inkling has also become eight characters, named after their ink colors (excluding Lemon, or Agent 3).
- Dying Declaration of Love: When Simon gets killed by the Reset Guardian, his last words before he dies are a confession of love to Bayonetta.
- Eaten Alive: During the Reset Temple arc, this becomes Mr. Game & Watch's demise.
- Early Installment Weirdness: At the beginning, Villager (specifically Vill) is presented as a violent psychopath. This was later retconned, though the offending chapter remains.
- He's Not My Boyfriend: In Chapter 198, Doc asks Leaf if Red's her boyfriend. She quickly denies with the above.
- Identical Grandson: The Links technically follow this, due to being the same person over multiple different reincarnations.
- Imaginary Love Triangle: Wolf, crushing on Isabelle, catches sight of her being affectionate with Digby during Visitors Week Part 6, resulting in him becoming bitter and disappearing. Naturally, this causes him to not show up to the meeting they had planned, leaving Isabelle disappointed. This gets resolved in Derailed 6, where Wolf finds out that Digby is in fact her brother.I... I need to sit down, Wolf muttered.
God, he felt like a fuckstick.
And, quite honestly, he was.
- Interdimensional Travel Device:
- The Smash Train, which is how new fighters arrive.
- In the Derailed Arc, the Inter-dimensional I-Van Is used to get to V169.
- At the end of the Derailed Arc, the Thanoscopter is used to escape V169.
- It's Probably Nothing: In Chapter 102 (Mii-pocalypse Part 2), Mewtwo is the only fighter to realize that Mario has been replaced by a Doppelganger Mii. After confronting him, he is stopped by Dedede, who is convinced that the Mii was the real Mario.
- Loads and Loads of Characters:
- Being a Super Smash Bros. fic, this is a given, but Audiomedic goes even further by making all of the assist trophies and stage background characters their own distinct characters, rather than programs.
- Taken Up to Eleven in Chapter 200, where all 168 important characters so far (or should I say 169?) make an appearance.
- The Lost Lenore: For this version of Richter, the "bad ending" of Castlevania: Rondo of Blood is canon, making Annette this. Averted for the Richter from V169, who got the "good ending" and is currently married to Annette.
- Love at First Punch: In Chapter 159 (The Masked Marauders), Lucina socks Solo in the jaw after he sneaks up on her. They later become a couple off-screen. Lampshaded by Eight and Female Corrin:Hit [Solo] off, Eight finished. I mean the mask. Hit the mask off of him!
Female Corrin laughed at that. I forgot about that! [Lucina] totally smoked the guy!
- The Matchmaker: In Chapter 38 (the Valentine's Day Episode), Red's Squirtle and Ivysaur hatch a scheme (which they share with Charizard and Leaf's Pokemon) to set up Red and Leaf with each other.
- Medium Awareness: Max from v169 is fully aware that the entire world is just words on a page.
- Me's a Crowd: When Toon Link grabs the Four Sword (that appeared through a rift), he splits into the four Links from Four Swords Adventures (and also releases Shadow Link).
- My God, What Have I Done?: Sonic post-Reset arc is unaware of why everyone hates him. A quick day out with his friends led to his memories being restored, forcing him to put the pieces together and realize just what he caused.
- Never Mess with Granny: In Chapter 75, Sandman, a boxer from Little Macs universe, is absolutely demolishing the competition in an unofficial king of the hill style boxing match. When Fiametta, Waluigis Grandmother, talks to the bruiser and scolds him for gloating, he responds by taunting the woman. To everyones surprise, Fiametta beats Sandman.
- No-Holds-Barred Beatdown: In Chapter 5, Villager delivers one to Wario (between scenes) for bullying Isabelle.
- Official Couple: Chad and Chelsea, the male and female Wii Fit Trainers, are married.
- Platonic Life-Partners: Snake and Samus, given their rather mature and snarky attitudes, plus Samus being the resident Lad-ette in the mansion allows her to trade barbs with Snake on occasion.
- Shipping Torpedo: In the beginning, Richter made it his mission to ensure that Simon did not have anything to do with Bayonetta, lest she corrupt him. However, after a talk with her about her intentions, he acquiesces and instead becomes a Shipper on Deck.
- Speech Impediment: Silv, the silver Inkling from V169."I'm an impuwity to Inkopolis because I can't say impuwe!"
- Symbol Swearing: The group chat has a profanity filter that (usually) replaces swearwords with asterisks.
- Time Travel Escape: The whole point of the Reset Arc was to bring back Master Core, but eventually it was also to get out of the temple at all. The whole arc is one big Reset Button Suicide Mission.
- The Trickster: In every appearance she makes, Jigglypuff draws on peoples' faces with a marker. However, this is because everyone keeps falling asleep during her concerts.
- Twin Telepathy: Pit and Dark Pit, to an extent. This is apparently a result of Dark Pit being a mirror clone.
- What the Hell, Hero?:
- In the Reset arc, Sonic suggests that the adventurers who made it inside the Reset Temple split up into groups of five. Naturally, this leads to more than half of the survivors either dying or being incapacitated.
- Leaf, despite her situation, also qualifies for this due to her decision to try and poison her team members (one of which was Sonic, funnily enough). Luckily, she only put them to sleep.
- Why Did It Have to Be Snakes?: Chad, the male Wii Fit Trainer, is deathly afraid of spiders, and gets his wife to deal with them. In the Reset Temple, he dies to giant spiders. Post-reset, he had lost his memories of the incident, but was violently reminded when Vill innocently came up to show him the tarantula he had just caught.
