"Day of the Atom (Part 2): Immortals"
The X-Men argue over whom this Xorn could be, but are stopped by the Eight Immortals. After a long fight between the X-Men and Immortals, Gambit is blinded by an attack. Havok blows all the Eight down, but accidentally blows a hole in the Xorn's helmet, causing the X-Jet to get sucked into the start of a black hole!
