(Iron Man Annual I#15 (fb) - BTS) - The Controller found a latent psychic named Sarah Jessup, then used his control technology on her, in turn using her powers to boost his control of others. He kept Jessup, bald and strapped to machines, in a coma-like state.

(Iron Man Annual I#15) - Controller continued manipulating Jessup to boost his own control of others. In a battle with Iron Man, Controller drew more psychic energy through Jessup, inadvertantly overwhelming Jessup, who became a crazed astral being bent on revenge. Calling herself Mindstorm, Jessup lashed out at the Controller and Iron Man with psychic energy, forcing them to experience each other's memories before Controller shut down the machine. Without more psychic energy influx, Mindstorm consumed herself, disappearing as Jessup cried out in pain.
