Lucina (USBIV)

Lucina is an unlockable playable character in Ultra Smash Bros. IV and makes her second appearance in the series since Smash 4. She was confirmed before Chrom's launch release in April 2013, the date when Fire Emblem: Awakening was released worldwide. It was also the date when Ultra Smash Bros. IV development started 2 months earlier, alongside with Marth, Ike and Robin. In the Fire Emblem series, Lucina is the daughter of Chrom from the future and she possesses the Parallel Falchion, the same sword as his father. She identifies self as the part of the Hero-King self, Marth.
Lucina is well-known to be Marth's total clone in the game, and the same as in the previous game. She's smaller from hurtbox and her attacks are totally similar to Marth. Her range is lacking due to having her sword where she doesn't have a proper tipper but the sweetspots are on her center of her Falchion (calling the name of the sword as the Parallel Falchion). She's more balanced and easier to fight with and it's practical for beginners.
Lucina's voice clips are reused from Smash 4.
Lucina ranks the 29th place of the 103rd in the tier list, putting her in the top tier classment (A) behind Pikachu and after Pit. This is a notable rise for Lucina being a high tier in Smash 4.
