Ranke

served as a knight in Haido's supposed "Utopian" army.

Personality
She was very impatient and bratty, saying out loud how she hated wasting her time on the machines to turn the orphans into Armors to battle. She also liked to tease her opponents and underestimated them, leading to her death at Gaara's hands. She was also very insulting to Temujin, calling him an idiot. She also seemed to face battles and fights as mere games, seeing it only as playtime, another thing which led to her death.

Abilities
Ranke could change her form to increase her power when using taijutsu. Using the power of the Stone of Gelel, she could utilize lightning techniques and transform her body into a larger, Frankenstein-like monster form. She was also shown to be very agile, as she was able to dodge an array of Gaara's sand senbons shot at her with relative ease.

Plot overview
In the beginning of the movie she had battled Gaara but she managed to escape. The second time she accompanied Kamina and Temujin to Sunagakure, and ended up in a fight with Gaara. After he neutralized her lightning attacks, Gaara killed her with the Prison Sand Burial.

Trivia

 * Ranke's Frankenstein-like transformation, along with Fugai's werewolf-like transformation and Kamina's bat-like one, could be perceived as parodies of three classic monster movies, namely Ranke as Frankenstein, Kamina as Dracula, and Fugai as the Wolfman (or woman in her case).
 * It should be noted that while in her Frankenstein transformation, her Plasma Ball is stronger. Ironically, the actual Frankenstein's Monster was brought to life using lightning.
 * It seems that she is the only one of the Haido's knights that can use elemental ninjutsu (although, considering that none of Haido's faction know what chakra even is, it cannot be considered to be true ninjutsu, but instead just converting Gelel energy into electricity and manipulating it).
