Tira (Soulcalibur)

Tira (later known as Darth Dunkelkralle) was a apprentice of  during the Soul Wars. She had formerly served Nightmare, embodiment of the cursed sword Soul Edge, which she believed to be a kindred spirit. When Nightmare apparently died and Vader claimed Soul Edge for himself, Tira pledged her allegiance to him. Through Tira, Vader manipulated others, such as, Sophitia Alexandra, and , into becoming servants and eventual sacrifices for Soul Edge. Vader also had Tira kidnap his son,, in an attempt to destroy the spirit sword Soul Calibur (a perfect replica of which Luke was wielding) and claim Luke as a apprentice.

Eventually, Vader and Tira together killed Vader's master, despite the great power that he had gained from the deceased Hero King Algol, and Tira was then given a Sith title as Vader became the new master and.

Personality and traits
Tira was highly schizophrenic, causing her to argue with herself about her status as Vader's apprentice. One of her personalities, a sadistic, maniacal and ecstatic Harley Quinn-like killer known as "Jolly Side", felt very affectionate towards her new master, while her other personality, an "emo"-type persona known as "Gloomy Side", detested Vader and desired to serve Nightmare once again. This ultimately led to her demise; Vader encouraged Tira to use the dark side of the Force to ultimately rid herself of her Gloomy Side, however this plan backfired and Tira rid herself of her Jolly Side, becoming Vader's enemy. Vader therefore choked and killed his apprentice out of necessity. However, he felt one last bit of sympathy for Tira as her ironically-named Jolly Side shone through during her death and she shed a few tears for her master, understanding the reasons for her death and knowing that Vader was killing the "other her".

Tira wielded a "circular lightsaber" named Eiserne Drossel that was modified from her previous weapon, a chakram-like "ring blade" that resembled a large hula hoop with a sharp edge. Her fighting style resembled bizarre, hypnotic dancing, and she would often create what she called "pretty pictures" using in battle.

At least in her Jolly Side mode, Tira developed a particular fondness for slaughtering and harvesting their souls, as she shared the same hatred for the Jedi as her master. She would often intentionally annoy them through childish taunting while killing them slowly and painfully.

Behind the scenes
Tira is a character from the Soulcalibur series of video games. Her only appearance in true (albeit non-canon) Star Wars material was in Soulcalibur x Star Wars, although she had already appeared alongside several Star Wars characters in Soulcalibur IV.

Trivia

 * Tira is one of three Soulcalibur characters in Soulcalibur x Star Wars to use Force powers and be able to wield a lightsaber-like weapon, the other two being and Kilik.
 * In the German-language version of Soulcalibur x Star Wars, Tira's Sith title was changed to "Darth Mortalis" because "Dunkelkralle" is a portmanteau of the German words for "darkness" and "claw". This name change was carried over to the French version as "Dark Mortalis".
 * As with Nightmare in previous Soulcalibur games, many fans have suspected that Tira has some sort of sexual attraction towards Vader; however, Vader's own feelings towards Tira, which he develops after learning about her troubled past and sympathizing with her, appear to be parental rather than loverly.
 * Like most other Soulcalibur characters in the game, Tira's default costume in Soulcalibur x Star Wars is directly based on her costume in Soulcalibur IV, save for the weapon, which now has a red lightsaber-like edge and several other lightsaber-like features. However, her alternate costume is based on her green outfit from Soulcalibur III, and the accompanying weapon resembles what it once was before the lightsaber blade was added.
 * Tira's "Destined Battle" in Soulcalibur x Star Wars is The Apprentice.
