Brainiac

Brainiac is a creature type used for cards that depict a intelligent Supervillain or his henchmen. It is exclusively used for the Unstable League of Dastardly Doom. All the brainiacs have the jars with brains as part of their head.

Unstable features three Brainiac creature cards:
 * The Big idea
 * Inhumaniac
 * Painiac

Trivia

 * The design of Brainiacs is possibly inspired by the DC comics character of the same name.
 * Gleemax is a brain in a jar, as well.
