The Sigma Force are first encountered by Trunks, Goku, and Pan on planet M-2 when they attack the group, taking Goku and Trunks. When General Rilldo realizes Pan is in the base, he sends Natt to deal with her. The robot seems to be winning with ease, but then Pan figures out he can only predict moves she has done before. She combines some of her moves with Goku's, and then destroys the robot. Later, when they battle with Goku, the Sigma Force (with the exception of Natt) fuse together to create one mighty robot, the Super Mega Cannon Sigma.
