Rozelena

Rozelena is a Toa of Water and a member of Hook's team.

Early Life
Rozelena was a Ga-Matoran who would later transform into a Toa. She was a member member of Toa Mizu, a six Toa team consisting of five Toa of Water and led by a Toa of Lightning. The team was later disbanded and the Toa were assigned missions on different islands. Rozelena was sent to Karda Nui where her life would change.

Jaller
Rozelena was attacked by the Makuta of Karda Nui and was sent crashing through the roof of Jaller, who was disguised as Shade's roof. The two formed a close bond, and Jaller gave her new armor after hers was ruined by the Makuta. After hearing Jaller's story, she convinced him to return to Hook's team. Rozelena went with Jaller and joined the team. When Jaller was transformed by the Makuta, she helped to save him.

Bara Magna
Hook's team, including Rozelena, was later exiled to Bara Magna. Jaller's evil Makuta half, Shaller would later kidnap Rozelena. Enraged Jaller went after him to save her. A brief hesitation during their fight when Jaller was trying to make sure she was okay caused him to have his left hand cut off by his dark side. Though seriously wounded, Jaller managed to beat Shaller and rescue the Toa of Water and carried her home. When Jaller was later killed by Shaller, Rozelena was affected the most and was given his mask by Hook as a keepsake. She was relieved when Jaller returned to life.

Universal Reform
After a battle against "Olmak Guy" that caused the destruction of Hook's Olmak, and damage to Hook's Vahi and Evnika's Ignika there was a sudden temporal displacement which caused the most of the Lightningverse and several other universes to come together and also caused several events to never happen such as the Makuta of Karda Nui's death and Jaller originally being a training robot, this lead to the creation of the Varuverse. Rozelena found herself traveling with Faitress, while wondering what happened.

Personality
Rozelena has a rather sweet personality and cares deeply for Jaller, being utterly heartbroken when he was killed. Despite her kindness, she can be quick to scold Jaller when he screws off during serious moments.

Mask and Tools
Rozelena originally carried a sword, which was later broken by the Universal Reform. She also uses the Rocket Pack Jaller made for her.
