Omicron

Omnicron was an artifical intelligence created by a race called the P'Shem to explore the rift. It had mapped a model of the universe onto the quantum tesseract fold inside his body. It could shapeshift.

The robot emerged from the rift at the Queens Arcade shopping centre. (COMIC: Rift War!: Part Seven: The Man Who Fell to Earth/Part Eight:The Enemy of my Enemy...)
