The Invoker, a Terraformar bestowed with genius-level intelligence, in addition to his already existing super strength (5.5 tons of lifting, can tear out spinal columns), super speed (casually blitzing Thien, who is faster than faster-than-eye-can-follow regular Terraformars), bulletproof carapace and flight through retractable wings. His main gimmick in the series is the fact that he tends to transplant body parts of defeated BUGS Surgery humans to his comrades, who gain full access to insect abilities.
Ultimatrix, the unstable version of the Omnitrix with trademark feature of mutating its DNA samples into million-year-long war of worst possible scenario simulation. A waterproof, bulletproof DNA alterer, Ultimatrix allows its host to transform into different alien forms, but can fire a beam that transforms other beings into alien if it's hacked.
Assuming that The Invoker has all aliens available to Ben during UA, how much of improvement would his new soldiers be over standard Terraformars? And would he be able to handle six ultimates escaping through a glitch?
