Wikipedia said:Brainiac is one of the most intelligent villains in the DC universe, known for having a "12th level intellect." The massive intellect allows for superhuman calulation abilites, enhanced memory, and advanced understanding on mechancical engineering, bio-engeneering, physics and other theoretical and applied sciences. Brainiac's advanced mental powers have shown him capable of possessing others, transfering his consciousness [2] creating and manipulating computer systems, and exerting some control over time and space. Brainiac has also created devices such as a force field belt [3], a shrinking ray capable of reducing cities[4]. The Byrne reimagining of the character possessed telepathy and telekenisis which were further augmented by a electrode head-piece. Brainiac's multiple host bodies have shown an array of abilities such as superhuman strength, durability, and energy projection.
I kind of wished I was this good, although the last few abilities are red herrings.
