Dada (ダダ) are a humanoid alien race that attacked Earth and started abducting humans to advance some form of research. The original agent, Agent #271, was killed by Ultraman. Since then, numerous other agents have traveled to Earth with varying goals. The members of this race are referred to by their registration number and class, rather than possessing given names.
True to their name, Dada are inspired by Dadaism, an art movement which began in 1915-1916 and spread to Japan in 1923. After their appearance, the Dadas became a famous symbol of Dadaism in Japan.
