New Avengers #1 (2012)

In Wakanda many years ago, Tony Stark convenes the first meeting of the group that would become known as the Illuminati. Tony proposes creating a unified group of all the world's superhumans. After some discussion, the assembled decide to meet in secret and discuss threats to the entire world. Despite having hosted the meeting, Black Panther warns them against this, and refuses to participate. In present-day Wakanda, a trio of promising youngsters solve the last puzzle of an obstacle course and are commended by T'Challa, King of the Dead and Black Panther, as the country's newest Makers. Suddenly, a startled rhinoceros breaks through a sort of barrier. T'Challa investigates and finds that the barrier is a veil. Behind it, the sky is dark and a second Earth looms large in the sky. Six figures descend from that Earth to land on Wakanda. The figures are a strike team, armed, and lead by an alternate-universe version of Manifold and a blond woman in black. T'Challa and the three teenagers confront them. The woman calls herself a Black Swan but denies that the dark sky and the encroaching Earth is her doing. She tells him she has come to destroy a world. When T'Challa replies that he will stop her, she calmly orders the guards to kill them. Two of the teens are killed instantly by blasts which break through T'Challa's shields. He takes the third, N'Kono, and runs for cover, but the guards find them and the boy dies in T'Challa's arms. The Black Panther goes on the offensive, killing the guards and working his way back to the Black Swan and Manifold. She takes a device from Manifold and asks if he can pay the "offering." When he refuses, she kills him with a blast from her eyes and directs the device at the world overhead. Just as she triggers it, Black Panther tears through the last of her guards and reaches her. He knocks her down, but the Earth explodes overhead and the world around him instantly returns to normal. The next day, T'Challa prays to Bast for salvation... from what he is about to do. One or two at a time, Tony Stark, Steve Rogers, Namor, Reed Richards, Doctor Strange, and Black Bolt -- the Illuminati -- are arriving in Wakanda.
