"Sentimental fool. T-20-0-6 isn't even capable of such silly affection. Friendship, trust...what can these things mean to a mutant robot strictly programmed to do his duty?"
— "Pan's Gambit"

Commander Nezi (ネージ Nēji) is a Machine Mutant created by Dr. Myuu, and is the leader of the elite Sigma Force.



Nezi, Natt, Ribet, and Bizu make up General Rilldo's top mercenary force, the Sigma Force. They are called upon when Dr. Myuu demands "results". Similar to the Pilaf Machine, Nezi and his elite have the ability to join their metal bodies into an even more powerful soldier, the Super Mega Cannon Sigma. This form is a fusion of the Sigma Force. They have a large variety of moves, such as eye beams and drills. They are easily beaten by Goku once he becomes serious.

Commander Nezi's Mega Cannon Punch

Before Goku escapes from his container, Nezi and the rest of the Sigma Force are fed data of Goku, Trunks, and Pan's fighting styles and techniques in order to fight against them. When Goku escapes, Nezi begins to battle with Goku, mocking Goku's skill throughout the match. However, when Goku eventually shows more of his power and starts to overpower the Sigma Force, Nezi and the others fuse to create the Sigma Force Cannon. However, Goku still manages to defeat the Sigma Cannon with relative ease.

However, it is soon revealed that Nezi and the other members of the Sigma Force had not been destroyed, and Rilldo has them ambush Goku during his battle with the Saiyan, the Sigma Force gain a hold on Goku and stopping him from moving. However, Goku quickly destroys them by transforming into a Super Saiyan. In response, Rilldo merges with the remains of the Sigma Force to increase his power.


Nezi and the other members of the Sigma Force are noted back and forth by Goku to have awesome/incredible power or to not actually be anything special power wise. While Goku is holding back Nezi is shown holding an advantage over, and hurting base Goku. After the three Sigma Force members overwhelm Goku, Nezi notes that his power level is short by over 100. However, Goku soon after manages to defeat the three Sigma Force members, forcing them to fuse together.

Due to Goku's remarks, it is clear that Nezi and the other members of the Sigma Force are strong compared to the previous enemies Goku had faced while in space but were not strong enough to challenge his current power.
