Brainiac XII is the Atomnitrix's DNA sample of a Cerebrocrustacean from the planet Encephalonus IV.


Braniac XII has a crab-like appearance. He has pincers for hands and four legs. He can open his skull plates at will to reveal his brain, which is pink in color. Brainiac XII has a black loin cloth with a blue stripe running across it on the bottom of his body. He has a black stripe in the center of his head with a blue stripe in the center of it. He has four legs and each leg has a black stripe on it's joint. He has hair-like spikes on his face and forehead and his eyes connect to a large black stripe that extends around his forehead. He has two spikes on each elbow. He also speaks in a deep voice with a German accent.

The Atomnitrix symbol is located on a blue and white neckbrace.

Powers and Abilities

Brainiac XII's cranium holds an immense brain, giving him super-massive intelligence.

  • He can solve difficult calculations mentally in roughly seconds.

Brainiac XII can produce and manipulate blue electricity in a variety of useful forms, including shoving or launching enemies, shocking enemies, creating protective coatings, or creating forcefields of energy, by opening exoskeleton plates of his skull.

He can create large energy bolts and and launch them.

  • Electrokinesis
  • Technokinesis

Brainiac XII is strong enough to crush a refrigerator using his pincers.

Brainiac XII has the ability to levitate above the ground.


Sonic vibrations can give Brainiac XII a headache and it make it hard for him to concentrate (suggesting concentration is needed to use his powers).

If his shell is closed when releasing electricity, it will shock and injure his brain.

It seems Brainiac XII can be shorted out due to the electricity in his brain.
