Falchion One was sent to the Sun to investigate a strange energy reading only to encounter the Kree who placed a huge teleporter on the Sun for their massive fleet to enter through and attack Earth. All except Peter Corbeau were wiped out in this encounter.
Falchion One would later perish by the Sun's intense heat when Black Panther volunteered to manually control the teleporter system at the seemingly cost of his life but later managed to escape successfully.
