In 2015, Nick Fury contacted the NEXUS Internet Hub and learned that Ultron had attempted to get America's nuclear codes but somebody was changing the codes all the time. In order to find their possible ally, Tony Stark arrived at the NEXUS base. While hacking into the NEXUS, Stark was shocked to find out it was J.A.R.V.I.S., who erased his memory and had scattered himself all across the Internet in order to block Ultron.
In an alternate 2015, Tony Stark, Steve Rogers, Thor, and Bruce Banner confronted Ultron at the NEXUS Internet Hub in order to stop him. However, Ultron overpowered them, killing Rogers, Thor, and Banner. Stark pleaded with him to stop as he had created him for peace, but Ultron rebuked him and used his full power to kill Stark, get access to the nuclear codes of every world power, and destroy the Hub.
