Cassandra

How Cassandra entered the Tourney
Before Super Smash Bros. was released on the Nintendo 64, Cassandra witnessed Taki bringing back an unconscious Sophitia and pulling a fragment of SoulEdge out of her sister's body. So when Sophitia left again for a second time, Cassandra knew that she had gone out to destroy SoulEdge. Then, four years after the events of Soulcalibur, Cassandra visits her and Sophitia's home, only to be greeted by the sight of Sophitia's two children fighting over a metal shard of Soul Edge that Sophitia's husband, Rothion, had found. Angered by her sister's panicked reaction, Cassandra ran to the "Eurydice Shrine", screaming at Hephaestus for endangering her sister on behalf of his ego. After briefly passing out from exhaustion, she saw the metal fragment resonating with the holy "Omega Sword", the sword her sister used on her past journey. Not wanting to see her sister take on another dangerous quest, especially now that she has a family, Cassandra stole the sacred sword and, sneaking out of her home, she took the task of destroying SoulEdge. After she destroyed SoulEdge, Master Hand appeared and Cassandra had no choice but to enter the Smash Bros. Tourney to defeat him.

Final Crush (Final Smash)
Cassandra says "Here we go!!!", then she slashes her opponent with her sword, knocks the opponent over with her backside, jumps onto them backside-first on the head while she asks her opponent "You like this kind of stuff?!", and then, after she places her shield under her bottom, slams her bottom into the head, shooting hearts everywhere. She says "Ugh..." and then falls to the ground while saying "OW!" afterwards, before falling asleep to recover the damage she has taken before her Final Smash.
