Okay, so I decided to return to elaborate on 4-Volt being that one person in Diamond City who just wants his coffee, but I decided to go into Warioware Smash Bros and Olympics headcanons.
A while after Mario and Luigi's Go-Kart tournament, Wario heard about Smash, and how Mario was always invited. Wario was furious because he felt both him and Waluigi had been stiffed out of a chance to humiliate the Mario brothers seeing as they never got an invite. They convince Kat and Ana to help them by painting Mario as an evil person(which is total bs Wario's been feeding them for a while). It's here they get manipulated by Tabuu into turning Peach into a trophy and Brawl happens (I'd say Bowser is being manipulated as well, considering he's basically been spending all his life trying to marry Peach and she's being turned into stone by the guys he's working with). When the rest of the cast find out about this, they take Dribble and Spitz's cab and attempt to figure out a way to the Smash dimension. Then they find a letter at the City Dojo which teleports them and their ride to said dimension.
Once arriving, they land in a giant forest, where they're almost run down by something that looks like a blue blur. Wait, it's Sonic the Hedgehog and Team Dark (Sorry, but as a Sonic fan, I saw an opportunity to let Sonic characters interact with WarioWare Characters and took it). Now Sonic has already met Wario, *They met after being teleported to an Olympics event a few months prior* and had just received a letter in his world that also sent him to the Smash dimension. At the same time, his rival, Shadow the Hedgehog recieved a letter with his team, and attributes the teleportation to a scheme of Eggman's. Both decide to team up with Warioware Inc to stop Wario. Meanwhile, Wario and Waluigi lose the trophies to King Dedede and get seperated from the Katana twins. Wario gets turned into a trophy and the islands gets sucked into Subspace...which includes the Warioware/Sonic gang.
The warioware gang notice the Katana twins being cornered by the koopa troop, who are being controlled by Tabuu via mind control. Shadow takes them all out while Sonic goes on ahead. Eventually, they find Waluigi and Wario who was going off on Luigi about how they deserved to get invitied...except it turns out they were for both Brawl and Melee. The only issue was that the letters were being sent to Wario's castle, not his house, as Mario and Co hadn't known that Wario wasn't living in his castle anymore. 5-Volt gives them the riot act and makes them promise to not try anything like this again. Spoiler alert, they do.
You know the ending, Sonic saves all of Nintendo and the island's get restored. Master Hand's boss was orignally meaning for his appearance to be a one time thing, but the rest of the fighters wouldn't allow that.
Kat and Ana are invitied to become assist trophies.
Since they know Sonic now, they get invited to the olympics that Wario gets to go to. I like to thing that in every olympic games between 2010 and 2019, Dribble and Spitz almost accidently kill a turqoise bird that isn't an oc of mine, but might as well be.
During the 2012 olympic games, Wario builds a snack stand to take advantage of all the saps' money at the games, and has Ashley and 9-Volt help him. Then Eggman and Bowser's latest plot to fill the city with Fog ruins that idea. While he goes off to "file a complaint", he leaves a 13 year old, a 9 year old, and an imp who is definitely not qualified to deal with this, alone. eventually, 4-Volt comes across them and he is borderline pissed at Wario for leaving his son (and pseudo-daughter) vulnerable to go chasing cash.
The short lived Waluigiscopes were co-created by the Crygors.
5-Volt actually was at the stadium and got to know Vanilla the Rabbit, plus Cream and one of their relatives.
The only reason Shadow was an assist trophy was to make sure Eggman didn't try anything, especially considering Bowser and other villains were participating.
Ashley attempted to become a fighter for Smash 4, but got her ass kicked by the Koopalings. She got bumped down to assist trophy but got comforted by...Shadow the hedgehog! *Couldn't resist making an interdimensional friendship between two of my favorite characters who probably have ptsd*
13-Amp got to accompany the crew to "Smash Ultimate" and had a 9-Volt-esque geekout upon meeting Sonic for the first time.
