Gylgax

Gylgax is Vilgax's brother who first appeared in The Brother.

Story
Gylgax is the only other brother of Vilgax who Vilgax contacted in The Brother in the hunt for Ben's Ultimatrix. Gylgax is a foot smaller than Vilgax, and kept himself a secret till Vilgax contacted. Gylgax failed to get Ben's Ultimatrix and ended up in the Oversky prison, but Ben suspects he will return.

Powers
Gylgax, like Vilgax in Alien Force, has stolen weapons as seen in his body. Some of his weapons are: As usual, Gylgax also has superstrength, can jump high, and is faster a bit than Vilgax.
 * Hyper Laser Electric (HLE) Cannon - the HLE cannon can shoot lasers or electrical blasts. It replaced Gylgax's arm after fighting wild aliens who ate his left arm.
 * Nanoflyers - the two red feet on his body have nanoflyers in them, enabling him to temporarily fly at high distances.
 * Multifunctional Discs - embedded in his chest, these discs can serve as bombs and release sonic waves.
