"We have combined to form one being of unparalleled military might...the all powerful Sigma Force Cannon!"
— "Unexpected Power"

Super Mega Cannon Sigma (スーパーΣ Sūpā Shiguma, lit. "Super Sigma") is the fusion of the Machine Mutant robots Commander Nezi, Ribet and Bizu.


Dragon Ball GT

Baby Saga

Main article: Baby Saga With the defeat of Natt, and then finding themselves on the losing end of a battle with Goku the remaining Sigma Force members, Commander Nezi, Bizu and Ribet, fuse to become the Super Mega Cannon Sigma to battle Goku. It appears to worry Goku, but in reality Goku is holding back, trying to figure out Super Sigma's moves and fighting style like they did with him before fusing. Goku then goes to his full power and effortlessly beats Super Sigma up, and ends the fight by hurling it in the sky and blasting it down with a Kamehameha.



The Sigma Force believed that they would be strong enough to defeat Super Saiyan Goku at the time when he was on Imecka.

During Goku's battle with Super Sigma, Goku after being hit by him states that he has awesome power, but then at the end of the fight goes on to state that he really isn't that strong. Goku notes that in his normal formation Super Sigma is slower than the three Machine Mutants who made him up due to his heavier body. When Goku releases his base form's true power he beats Sigma without any trouble.

Despite Goku defeating the fused Machine Mutant with ease, it should be noted that Sigma is the second strongest Machine Mutant on Planet M2, second only General Rilldo. Goku's comments on the power of him and his fusee's establish how much stronger they are than Luud, the previous Machine Mutant. But it also serves to show how drastically Goku had powered-up compared to the data that Giru had given Sigma on him.
