Super Intelligence is the main power of Chase Davenport. Super Intelligence is the bionic ability to be incredibly smart, which gives one a brain capacity higher than those with genius-level intellect.
Chase (and Douglas) even go as far to say he is "the smartest person in the world" (Twas The Mission Before Christmas, Robot Fight Club, Smart and Smarter, Bionic Dog). Some bionic apps require super intelligence to be used.
Only a handful of bionic people have this ability, as it is extremely difficult to crack. In Bob Zombie, it's revealed that Adam and Bree aren't able to get this ability because their chips are older models. The only other other being with Super Intelligence besides Chase was Marcus.
