List of victory poses (SSBU)
All of Bayonetta's victory quotes are based on taunts from Bayonetta 2 while wielding various weapons; the associated weapon for each is listed in parentheses.
In any victory pose, there is a chance Chrom will say "Our bond is stronger than steel." ("いつでも稽古をつけてやる", We can practice anytime.) if Lucina was present during the match.
All of Inkling's animations are based on the victory poses when using particular weapons in Splatoon and its sequel. The animations vary between female and male costumes.
Note: Joker has a unique victory screen based on the results screen from Persona 5.
The color of Joker's victory screen can also change. If playing on any stage other than Mementos with three or more players, Joker's results screen color will match the player port color (though the background will remain red). If playing on Mementos, Joker's results screen will match the color and aesthetic of the stage, and his victory theme will change to music from the corresponding game. The color of Mementos takes priority over his team and player port color. If Stage Morph triggers, the victory theme's color will remain if Mementos's song has played. However, this does not occur if the song plays on a custom stage.
If Joker is in a Team Battle and someone else is in front, he uses a unique animation: he tightens his glove, similarly to the pose he does at the end of his Final Smash, then assumes a pose similar to his idle stance. 
Note: Outside of Team Battles, Kirby's victory poses have three separate Kirbys, referencing the Kirby dances from his home series.
Little Mac wears a Champion belt in all three of his victory poses.
In all of Little Mac's victory poses, Doc Louis will say one of the following quotes random depending on which pose is selected and which costume is used:
The male Pokémon Trainer can say "You all did great!" ("よくやったな, みんな！", Good job, everyone!), while the female Trainer can say "Everyone did great!" ("みなさんは素晴らしい！", All of you did great!). They will either say their non-specific line, or a Pokémon-specific line. In Team Battles, if there is more than two players on the winning team, the Pokémon will not be present, but this does not affect the Trainer's lines. The male and female Trainers also have variations in their own pose depending on the gender of the Trainer, similarly to the Inklings.
During Squirtle's victory poses, the Pokémon Trainer might say "Good job, Squirtle!" ("よくやったな、ゼニガメ！"), while the female Trainer can say "We did it, Squirtle!" ("やったね、ゼニガメ！").
During Ivysaur's victory poses, both Trainers can say "Way to go, Ivysaur!" In Japanese, the male Trainer says "がんばったな、フシギソウ！", while the female Trainer says "がんばったね、フシギソウ！", both of which translate to "You did great, Ivysaur!"
During Charizard's victory poses, the Pokémon Trainer might say "You did it, Charizard!" ("リザードン, みなさんは素晴らしい！", Charizard, you're the best!), while the female Trainer can say "You're amazing, Charizard!" ("すごいね、リザードン！", Amazing, Charizard!).
Steve's Up victory pose was changed in update 9.0.1; previously, Steve held the Steak even after he finished eating it. This was removed presumably due to its phallic appearance at the victory pose's camera angle.
Both the female and male Wii Fit Trainers have a selection of sayings picked at random depending on which victory pose is used:
In any victory pose, there's a chance Wolf will say "Playtime's over, Star Fox!" ("遊びは終わりだ、スターフォックス！", Playtime is over, Star Fox!) if Fox was present during the match.
