Tomorrow Woman was one of the many superpowered androids created by Professor Ivo and his scientific colleague Professor T. O. Morrow. She was created as a Trojan Horse sent to destroy the newly formed Justice League. The scientist provided her with a four lobed brain which allowed her vast telepathic and telekentic abbilities. However her true purpose was that of a living bomb designed to go off at a specified moment and kill the entire Justice League. Tomorrow Woman learned the truth of her origin and canncelled out her programming discovering the concept of freedom, which her creators forgot to provide in her programming for obvious reasons. She sacrificed herself in order to stop a futuristic war machine by triggering an EMP bomb located in her body, which was originally intended to wipe the brains of the Justice League.
It was revealed that T. O. Morrow had seen this coming and was thrilled by it all he cared about wa his creation was working. Professor Ivo thought that the body he had made, which was realistic enough to fool even Superman's and the Martian Manhunter's heightened senses. T. O. Morrow proved him wrong however, as the brain he himself had created was sophisticated and human enough to develop her own personality and feelings, and turned against her creators. She sacrificed herself rather than murder the Justice League, and a statue of her has been erected in the Garden of Heroes.
