"I like you guys, you're fun!"

Rubytune (ルビーチューン Rubīchūn) is a young Crystallite and one of the major villains of Kyoumei Sentai Beatranger.


Phasing Incident

Some time before the beginning of the series, Rubytune stowed away on a small exploration craft that was part of an expedition to the uninhabited region of her homeworld. During the expedition, the craft was struck with a powerful bolt of energy and crashed. When she emerged, she found herself and the others in the craft in very unfamiliar territory. Even though everything was different from what she knew, Rubytune saw it all as fascinating and left the crash site, intent on finding something fun to do.

Encountering Beatranger

(to be added)


Rubytune is a young Crystallite, and it shows. Her main priorities seem to be her own happiness and well-being, no matter how she obtains them. She has an endearing fascination with music and dance. She also seems to have no interest in studying or dominating the world, like Emeralda and Meloquarz.


Like other Crystallites, Rubytune can detect resonance and disguise herself, but she also has the unique ability to amplify resonance around her. She is also quick, agile, and quite sneaky.


Rubytune's appearance is close to humanoid, though she has glassy, deep red skin, equally glassy black 'hair', and a smaller stature than most humans. Her outfit consists of a black coat under bright red armor, gold pants, red boots, and gold armbands.
