Alterna

In at least one universe, Alterna was the mascot or avatar of the Altern Corporation, and served an Alexa/Siri-like role in the form of a hologram that could be projected from Altern-developed digital devices. Alterna appeared as a grey, faceless humanoid figure resembling an artist's mannequin. It was unclear whether Alterna was a mere interface or an actual sentient A.I.
