Sunset Bain

Baintronics and Sunset returned to Tony Stark's radar when he discovered her company had used illegally-acquired Stark tech to develop an advanced military vehicle called the Manticore. As Iron Man, Stark confronted Bain and convinced her to hand over the Manticore.[11] Not long afterwards, Bain became assosicated with Tony's adoptive brother Arno Stark.[12] When Tony Stark launched to the public a virtual reality called the eScape, Sunset allied herself with the villain the Controller. The Controlled hijacked the eScape interfances used by consumers to enthrall and leech off their mental energies, and employed a Baintronics manufacturing and fulfillment center to send them real-life weapons all over the world.[13] Feigning no responsibility, Sunseit sent her security team to help take down the Controller.[14] Under the pretense to offer help, she also requested partial access to the eScape's network, which was used by Arno to gain full access and steal data in Chicago.

After Tony Stark became convinced that he was an artificial being and a simulation of the real, late Tony, Sunset and Arno colluded with Senator Miles Brickman to question Tony's status as a real person.[16] In the end, Arno helped delegitimize his own brother, and took control of his company, Stark Unlimited. Afterwards, he and Sunset merged S.U. with Baintronics
