Full Name: Sigma 682440
Portrayed by: Felipe Izquieroo
Notes: Sigmasix is the ultimate badass, a strong athlete who was raised on stereofoods before they were outlawed, resulting in his strength and giving him a significant advantage on the hypergrid. Feared by most people in Tamashas and especially by Kappatoo.
You really wouldn't want to get on the wrong side of Sigmasix, he will hold one hell of a grudge and hound you forever, not to mention his crazy Aunt!
