Nero Claudius Caesar Augustus Germanicus was the the Fifth Roman Emperor and in Nasuverse (the universe of Fate/Stay Night) she is a woman even though history says she was a man (it's long story) and she is one of the three main playable characters of the Fate/Extra series, which began as a spin of Fate/Stay Night, where she appears as a Saber-class Servant. The other playable Servants in Fate/Extra are Tamamo No Mae, a Caster-class Servant and EMIYA the Archer-class Servant. In addition to she is also a main character in Fate/Extra, Fate/Extella, Fate/Extella Link, and she is also playable in Fate/Extra CCC and Fate/Grand Order. The names of her Special moves are in Latin and I will include an English Translation in the parentheses.

Specials

Neutral Special

Technique Select

This move would open open a menu similar to Shulk’s Monado Arts with three options: Attack, Break, and Guard. Attack would be a quick slash with the lowest start and end lag, but it would also be the weakest. Break would be slow, but very powerful and will break a full shield if it hits. Guard would be a counter and it’s power would be between Attack and Break.

Side Special :left_right_arrow: Fax Caelestis (Celestial torch)

This technique was originally the signature move Nero's bride costume from Fate/Extra CCC. Nero dashes in the direction inputted while she swings her sword.

Up Special ↑

Tempestus Primavere (Tempest fountain)

This omve would work similarly to Pikachu's Quick Attack, except Nero would be able to switch directions 3 times.

Down Special ↓

Tres Fontaine Tempestes (Triple tempest fountain)

This technique would creates a a poisonous thorny bush about the size of Kirby if he ate a Super Mushroom. It would deal damage to a character that touches it for a few seconds like Joker's Eigaon and it could also be launched by a move that does a lot of knockback, like Pac-Man's fire hydrant.

Final Smash

Aestus Domus Aurea: Invitation to the Golden Debauchery Theater (Golden Theater of the Deranged)

This is the arena built Nero in 64 AD. Pressing the B button when Nero can use her Final Smash would make her dash in the direction she is facing and a short cutscene would play like King Dedede's Final Smash as she uses Laus Saint Claudius.

Laus Saint Claudius (Hail Saint Claudius)

Fax Caelestis (Celestial torch)
