7 Things You Didn't Know About Marvel's SECRET Infinity Stone

Since Sersi was in possession of the Ego Stone, she tracked down the other six and resurrected Nemesis.

Nemesis sees the Infinity Stones as her children and was disgusted by how they were misused. Although her death birthed the multiverse into existence, Nemesis was dissatisfied by her creation and believed the Marvel Universe and the Ultraverse had to be undone. Before the heroes had a chance to stop her, Nemesis obliterated the two realities in the blink of an eye.

Since Nemesis sees creation as her primary function, she felt compelled to construct a brand-new universe. She conferred with the Infinity Stones, each telling her how they would weave their own version of paradise. She kept tweaking the Ultraverse and Marvel Universe, trying to find the perfect balance. Eventually, Nemesis realised that she was going about it the wrong way. To create a perfect reality, she couldn't paint over a pre-existing universe; she needed a blank canvas. For her work to be completed, every other universe had to be expunged.
