Sigma is one of the characters from Pop'n Music 15 ADVENTURE, and one of the primary characters from the Zektbach franchise.


The temple sparkling in light is the head. Those who disobey the law.
If she touches to thy anger, they will receive the sky's judgement only.
..Which, it is frightening.

Sigma is a memeplex that the rural people combined.


Sigma is a female goddess figure with keen, sky blue eyes. Her hair is formed into a freakish appearance and animates like an electric spark, and carries a yellow color with a sky blue change, continuously moving. Sigma is shown wearing a white toga for females with a small, light blue gradient on top; underneath is her dress with the gradient from the lighter version of blue to the darker form. She have golden rings on the bottom of her breasts, and on her right shoulder. She wields a staff that blends into a lightning bolt on top with yellow to violet gradient. Sigma also wields a small, black shield and a hat with the respective colors of blue and yellow for her accents.

Sigma's 2P color palette changes her blue ombre and violet gradient from her staff to white. A light yellow gradient is found on the bottom of her toga, and her dress carries yellow, blue, purple, and magenta colors on her dress as a gradient. The shield and hat are white instead of black, as her jewel of her shield is magenta. The facial features and accents for her attire and weapon remain in their colors.
