Wellenreiter Artificial Intelligence is an interactive artificial consciousness programmed to operate the Wellenreiter's critical systems on Earth-X. Its holographic appearance is strikingly similar to that of the Gideon system that will be created by Barry Allen along with the Gideon system that helps the Legends aboard the Waverider. The main difference is that this artificial intelligence is red in colour. The voice of the AI is Susanna Thompson, who plays Oliver's mother in The Arrow.
Wellenreiter Artificial Intelligence is shown to work as a version of Gideon in the Waverider. It helped to pilot the Wellenreiter timeship to drop an explosive similar to a neutron-bomb onto Earth-1. While Overgirl was suffering from too much solar-radiation, it diagnosed that she would be dead within 1 hour unless she received a new heart. Eventually, it was attacked by Caitlin Snow, Zari Tomaz and Amaya Jiwe, who shut down the timeship's shields, and it was destroyed by Harry Wells.
