Franchise: Super Smash Bros.

All lines spoken by Marth in Melee/Brawl/Wii U and 3DS are in Japanese. These are what they all are translated:

Marth's taunt - "Everyone, please watch me!" ("みんな、見ていてくれ！")
Marth's counter - "There!" ("そこだ！"), "I won't let you!" ("させるものか！")
Marth's victory poses - "This time, victory is mine, right?" ("今回は僕の勝ちだね。"), "Today, too, I managed to survive." ("今日も生き延びることが出来た。"), "There's no way I can lose!" ("僕は負ける訳には行かないんだ。")

He also has an unused sound file in the Debug Menu of the game which is "Let's Dance!" ("レッツダンス！")

Mario's Cape attack can be used on a taunting character to make them face the other way in ways that are otherwise impossible, like making Wario face the screen while doing his side taunt.

Peach's Final Smash since Super Smash Bros. Brawl is a piece of music from Super Mario Bros 3 that has been sped up. The music is from World 5: The Sky, Coin Heaven bonus levels and in the Warp Zone.
