Big Brain is the Super Unitrix's DNA sample of a Galvan from the planet Galvan Prime in Age of the Unitrix.


Big Brain is a grey-skinned, frog-like bipedal humanoid standing just under half a foot tall. She has large green eyes, which have rectangular pupils, and wears a yellow jumpsuit. She has two thin tendrils coming from the back of her head, vaguely resembling hair. Strangely, the Unitrix symbol appears on the back of her left hand.

Transformation Sequence

Extract from The Paradox Problem, When Ann first used Big Brain on-screen:

"As the familiar green glow consumes her, she turns a sickly grey. Her hands enlarge, and so do her eyes. Her pupils become straight horizontal lines as her sclera become a bright green. As if this form were wearing its own unitrix, the unitrix symbol appears on the back her left hand. Just as the transformation appears to halt, Ann shrinks to only a foot tall."

Powers and Abilities

Big Brain's main ability, as her name would suggest, is her massive intellect. This intelligence allows her a great understanding of machinery and devices, as well as the ability to build and reconstruct machines with relative ease.

Her small size can be of great help when working with machinery, helping her to climb inside them easily. This is aided by her ability to climb things with the microscopic suction cups on her hands and feet.


Big Brain is very small and fragile, and is therefore incredibly poorly suited for combat. This can be extra troublesome because Ann cannot select the alien she transforms into.

Big Brain can also be quite arrogant about her intelligence, which is not a characteristic Ann has with any of her other aliens.


Big Brain was first used by Ann whilst she was testing her aliens in Los Soledad prior to The Paradox Problem. She was later used by Ann to help her and Kenny identify the Time Monster, until Professor Paradox grabbed her and forcably turned her into Flytrap. Ann used her to demonstrate the Super Unitrix's multiple forms to her parents in Centaur of Attention.
