Roxy

is a member of the Seven Catastrophes appearing in The Seven Deadly Sins: Grand Cross. She holds the title of Roxy of Madness, representing her mental instability resulted from the trauma after her sister's betrayal.

Appearance
Roxy is a woman of average height with light skin, long blonde hair in two pigtails, green eyes and wears a spiked choker.

After escaping from the Sabnak's memory realm, she reverts to her warrior slave attire and now ties her hair in a messy ponytail.

Whenever she activates her rampaging powers, her eyes assume a glowing red tone.

Personality
Roxy can be very cruel and merciless, as shown when she completely decimated Ordan Village with no sights of remorse under Lillia's request. However, she can be a bit altruistic, in her own twisted way, with people passing through extreme situations such as victims of human trafficking, most likely due to her past as a slave.

She also demonstrates to be extremely short-tempered and is constantly arguing with Eastin for banal things, something Camila compares as two sisters arguing. During her free time, she displays a bit of laziness.

Roxy's most notorious personality trait is how she can become mentally unstable during a battle.

History
Roxy used to be a warrior slave at her original world before getting summoned by Lillia to Britannia. She agreed on joining the team in exchange of food and a place to sleep.

At some point, Roxy complained to Lillia about the fact they hadn't a good-looking man on the team, something that possibly influenced on Shin's summoning.

When Eastin and Roxy's fights turned unsustainable for Valenti's experiments, the group went on a journey to find a new place to use as their hideout and installed themselves on an isolated island near Porto City

Abilities and Equipments
She uses a spiked flail which creates powerful explosions whenever it strikes a target. After having magic lessons with Lillia, Roxy managed to use her magic for other purposes such as summoning and fixing damaged objects, however, she still posses a very volatile control over her spells, as noted when she, attempting to fix Shin's tablet, ended summoning the characters from his King of Fighters' game into the real world.

After escaping from the the memory realm created by Sabnak, she awakens a rampaging power that drastically increases her physical strength and speed, as well as retrieve two chainswords she once stole from the guerrila that attacked her sister on her original world which she uses together with her fire magic. However, this new power appearently causes her to oftenly hallucinate with her traitous sister.

Abilities

 * Roxy spins her flail, creating a magma circle to attack her enemies.
 * Roxy launches her flail at the target and causes a massive explosion.

Lilia
According to Roxy, Lilia was the first person to not be interested on her due to her appearance, but for her destructive powers, something that caught a bit of Roxy's respect for her. She respects her as the leader of the group and will follow Lillia's requests without question, even when she doesn't agree with them.

Valenti
Roxy seems to be good friends with Valenti, as she is seen cheering her up during the fight on the King of Fighters' tournament and when she agreed on help on her research collecting battle data from Lilia's Awakened Form.

Mono
Roxy and Mono seems to get along, as they occasionally go on missions together and are both training to develop their powers under Lilia's aid.

Eastin Amabyllis
Eastin and Roxy have a complicated relationship, Eastin usually scolds her for acting as "barbaric", Roxy, on the other hand, sees this as reason enough to start a fight with her. The two's arguing got so bad they exposed themselves while in hiding on a mission, causing Camila to scold them. Despite this, Roxy seemed impressed by Eastin's skills as she stopped the under-construction base from being flooded by Skira, later commending her on a job well done.

Shin
Roxy acts like a younger sister to Shin. She occasionally insists to follow him in some of his missions and often attempts to annoy him by stealing his things or making fun of his fears. Roxy, however, doesn't seem to know to stop when her humor actually upsets Shin. Despite that, she appears to have had a crush on him, though potentially having gotten over it as she has since been on trips to the beach to find herself hot men.

Trivia

 * Roxy might be based on the first disaster of the Lotus Sutra's definitions, fire, due to her fire-based powers.
 * According to Grand Cross data:
 * Roxy despises King's human form because it reminds her of men who did something terrible to her.
 * Roxy loves beef, something that Shin occasionally use as an excuse to prevent her to cause a rampage.
 * During her free time she occasionally likes to flirt with men she finds interesting.
 * Roxy's battle animations and in-game cutscenes posses some references from other media.
 * Awakened Roxy's walking animation on her Ultimate move is a reference to Death from Puss in Boots 2: The Last Wish.
